Summary of Invasiveness
Top of pageNephrolepis hirsutula is a fern native to Asia and the Pacific, and is not recorded as having spread outside of this region. N. hirsutula is reported as an invasive species is in Cuba, however this is due to a misidentification of Nephrolepis brownii. N. brownii, which is considered an aggressive invasive species, is an Asian fern species that has been introduced in the New World. Within its range in Southeast Asia, Australia and the Pacific, N. hirsutula is not considered invasive.

Notes on Taxonomy and Nomenclature
Top of pageFerns are the informal name given to a diverse group of vascular plants with over 10,500 species (Christenhusz and Chase 2014). Most living fern species are leptosporiangiate, defined as ferns having the sporangia developing from a single cell and producing a definite number of spores (Schuettpelz and Pruer, 2007).
Nephrolepis is a pantropical genus of approximately 19 species (Hovenkamp and Miyamoto 2005), and it is probably the most popular source of commercially used fern species (Yahaya et al., 2016). The name comes from the Greek ‘nephros’ (kidney) and ‘lepis’ (scale), referring to the shape of the indusia in some of the species (Bell, 2017).
The identification of some species has been confusing; being difficult in immature fronds and further complicated by the hybridisation reported occurring mostly in cultivation (Yahaya et al., 2016; Bell, 2017). The species name N. hirsutula has not been consistently applied across the literature, mostly due to incorrect use and confusion with N. brownii. N. hirsutula has been misidentified as N. brownii, or both have been treated as a single species (Hovenkamp and Miyamoto, 2005; Caluff and Regalado, 2011) Also, synonyms of other species have been wrongly applied to N. hirsutula (Missouri Botanical Garden, 2018; USDA-ARS, 2018). Hovenkamp and Miyamoto (2005) provide keys to the identification of the Nephrolepis species and also give detailed information of the characters used to distinguish between some of the species. Based on molecular studies, N. hirsutula and N. brownii are not closely related (Hennequin et al., 2010; Yahaya et al., 2016).
According to Christenhusz et al. (2011) and later Vernon and Ranker (2013) the family placement of Nephrolepis is an unresolved issue, suggesting a tentative use of Nephrolepidaceae. Christenhusz and Chase (2014) suggest placing the Nephrolepidaceae within the subfamily Lomariopsidoideae, and in the Polypodiaceae family. As this classification is not currently being widely accepted, the Nephrolepidaceae family is used in this compendium.
Description
Top of pageThe following description is from Hovenkamp and Miyamoto (2005):
Plants forming tufts of 4–8 fronds (or more). Runners often forming stilts supporting the erect rhizome, 1–2 mm thick, branching angle narrow. scales on runners sparse or dense, appressed or spreading. Tubers absent. Fronds 90–210 by 15–20 cm, stipe 32–80 cm long. Lamina base reduced, tapering over 15–30 cm (or more), basal pinnae 3.5–8 cm long, 2–5 cm distant, middle pinnae straight (sometimes recurved). Sterile pinnae 8–10 by 1.2–1.6 cm, herbaceous, thick, base strongly unequal, basiscopic base truncate or rounded, acroscopic base truncate, strongly auricled (with narrow auricle), margin in basal part entire, towards apex crenate, apex acute. Fertile pinnae 7.5–11 by 0.9–1.1 cm, more strongly crenate than the sterile pinnae. Indument basal scales peltate, appressed, 1.5–23.5 by 1 mm, central part dark brown or blackish, shining, hyaline margin wide, ciliate, marginal glands, absent apex obtuse, rachis scales very dense, with a well-developed protracted acumen, spreading or squarrose, rufous, acumen strongly dentate. Scales on lamina usually persistent. Hairs absent from lamina and costae. Sori submarginal to nearly medial, 24–33 pairs on fully fertile pinnae, round, not impressed. Indusium reniform, with open sinus, attached at sinus.
Distribution
Top of pageAccording to Hovenkamp and Miyamoto (2005) N. hirsutula occurs in the southeast of Asia, throughout Malesia, to Australia and the Pacific, and distribution records elsewhere are due to a misidentification of N. brownii. The species has been wrongly reported as occurring in North America, Central America, South America and the Caribbean (Oviedo Prieto et al., 2012; García-Lahera, 2016; Encyclopedia of Life, 2018; Missouri Botanical Garden, 2018; USDA-ARS, 2018).There is some debate about the extent of the native region of the species at some of the Pacific region, being regarded as both native and introduced in Hawaii (Moomaw and Takahashi, 1960; Vernon and Ranker, 2013)
The wrongful attribution of synonyms is also adding to the confusion in the distribution reported for N. hirsutula. For example, in Missouri Botanical Garden (2018) some of the synonyms listed for N. hirsutula are synonyms of N. exaltata or N. brownii. In USDA-ARS (2018) GRIN online database N. multiflora is used as a synonym for N. hirsutula.
Nephrolepis hirsutula is recorded as as an invasive species in Cuba by Oviedo Prieto et al. (2012), but this is due to a misidentification of N. brownii, which is considered an aggressive invasive species and has been introduced in the Caribbean (Kairo et al., 2003). N. brownii is not listed as invasive by Oviedo Prieto et al. (2012). The authors cite Florida Exotic Pest Plant Council (2009) for N. hirsutula as being invasive in Florida, USA. Neither the FLEPPC invasive plant species list cited or the most recent one for 2019 (Florida Exotic Pest Plant Council, 2019) list N. hirsutula as an invasive species for Florida. The Nephrolepis species appearing in the list are N.brownii (= N. multiflora) and N. cordifolia. In an invasive report for N. hirsutula in Cuba, Caluff and Regalado (2011) report the synonyms of the species as being N. multiflora and Davallia multiflora, which are synonyms of N. brownii (Hovenkamp and Miyamoto, 2005; The Plant List, 2013).

History of Introduction and Spread
Top of pageAccording to Hovenkamp and Miramoto (2005) the species is found only in its native range and it is not spreading into other regions. There are spore records from 10,000 years ago from what is believed to be N. hirsutula from Sumatra, Indonesia (Morley, 1982).
Risk of Introduction
Top of pageWithout further details about the biology, the environmental requirements and the possible effects over non-native habitats, it is difficult to assess the risk of introduction. However, with the use of other Nephrolepis species as ornamentals, their spread facilitated by its stoloniferous vegetative reproduction and the easiness of spore dissemination it is highly possible that N. hirsutula could spread from its native area and slowly progress its way into suitable areas.
Habitat
Top of pageN. hirsutula is reported as growing in grasslands, forest edges, open forests, ridges, scrublands, rainforests, and low elevations (Ridley, 1926; Kingston and Waldren, 2003; Banaticla and Buot, 2005; Bell, 2017). It is also reported at margins of freshwater lakes in Papua New Guinea (Chambers, 1987).

Biology and Ecology
Top of pageGenetics
Molecular work shows that N. hirsutula is more closely related to N. biserrata than to N. brownii (Yahaya et al., 2016). The authors also report the species as being a tetraploid (2n= 82, 164), although Manton and Sledge (1954) report the species as being diploid (n=41).
Nephrolepis hirsutula has been suggested as one of the parent species of the hybrid Nephrolepis exaltata var. bostoniensis (Encyclopedia of Life, 2018). However molecular studies by Yahaya et al. (2016) found that N. hirsutula did not contribute to this hybrid species.
Reproductive Biology
Although no details are given for the reproduction of N. hirsutula, it is highly likely this species reproduces vegetatively through stolons or by spores, as most of the other Nephrolepis species (Yahaya et al. 2016).
Environmental Requirements
There is little detailed information available for the environmental requirements of N. hirsutula. The species grows on clay banks near water or in crevices of rock outcrops in Australia (Bell, 2017; 2018). In Papua New Guinea it is reported as growing in lowlands, in infertile, serpentine soils and in organic alluvium; with a mean annual rainfall of 3000 – 4000 mm (Takeuchi, 2003).
In Guangdong, China, it is reported in red soils in subtropical areas with an annual average temperature of 22°C and an annual rainfall of 2380 mm (Wang et al., 2006). In Hawaii, the species is reported as growing in nutrient poor soils, gravelly silty clay and volcanic soils with high infiltration rate; in an average temperature of 23°C, with a range between 13°-90°C; and in an annual precipitation of 1250 to 3810 mm with a relative high humidity (Moomaw and Takahashi, 1960).

Uses
Top of pageSocial Benefit
Godwin and Harvey (1944) report N. hirsutula is used as food, but give no further details. The scales from the midrib are used in treating the scab of male circumcisions (Whistler 1990). The fronds are sometimes used for leis, house decorations, and mulch (Whistler, 1988). The fronds are worn on the head as protection from sun or rain and used by women as carrying-pads (Bodner and Gereau, 1988).
Environmental Services
The fronds of N. hirsutula are reported as habitat for mites, without causing any damage (Huang, 1991). It is eaten by feral goats (Capra hircus) in Raoul Island, New Zealand (Parkes, 1984). N. hirsutula is reported as being capable of arsenic accumulation (Wang et al., 2006).

Similarities to Other Species/Conditions
Top of pageHovenkamp and Miyamoto (2005) provide keys for the identification of the Nephrolepis species. N. hirsutula is mostly confused with N. brownii. N. brownii has the sori close to the margin while in N. hirsutula the sori are less close to the margin to nearly medial. N. hirsutula has dense, rufous rachis scales with a very strongly dentate acumen. N. brownii has usually sparser, paler rachis scales, with a longer, nearly always entire narrow apex. The upper costae in N. hirsutula is glabrous.
N. hirsutula can be distinguished from N. biserrata as the latter is not densely rusty wooly, but scaly. N. cordifolia and N. exaltata pinnules are oblong to oblong-lanceolate and acute to round at the apex, while N. hirsutula pinnules are linear-lanceolate, and attenuate toward the apex (Fosberg, 1943).
Gaps in Knowledge/Research Needs
Top of pageMolecular studies are needed to assess generic and family delimitations in ferns (Smith et al., 2006; Christenhusz et al., 2011). More information on the biology and the environmental requirements for N. hirsutula is needed. Herbaria collections should be verified, and field work is needed to better assess the distribution of the species.
