Notes on Taxonomy and Nomenclature

Top of page
T. gallica is one of a group of closely related invasive species in North America, which also includes T. ramosissima, T. chinensis and T. canariensis. Hybrids may occur between T. gallica and all these species, but most commonly with T. canariensis (Gaskin and Schall, 2002, 2003).
For further information on the weedy deciduous Tamarix species, see the full datasheet on T. ramosissima.

Description

Top of page
Most morphological features are similar to those of T. ramosissima but T. gallica differs from that species and from T. chinensis in the insertion of filaments on the lobes of the nectary disc rather than between them (well illustrated in Gaskin and Schaal, 2003). It differs from T. canariensis in bract length (at least as long as the calyx in T. gallica, only half as long in T. canariensis) and in sepals (entire in T. gallica, distinctly denticulate in T. canariensis) (Baum, 1968).

Distribution

Top of page
T. gallica has a restricted native distribution in southwestern Europe while its introduced range in USA is somewhat sporadic, mainly in southeastern states but also in California and New Mexico. Gaskin and Schaal (2002) note that the hybrid with T. canariensis is prevalent along the gulf coast of Louisiana and Texas, while hybrids with T. ramosissima and T. chinensis occur in the western half of Texas.

Biology and Ecology

Top of page
The biology of T. canariensis is generally comparable with T. ramosissima (see the datasheet on that species), detailed data are lacking.

Notes on Natural Enemies

Top of page
Most of the work on natural enemies has been carried out for T. ramosissima (see the separate datasheet for more details). It is reasonable to expect that the same pests could attack T. gallica.

Similarities to Other Species/Conditions

Top of page
Details of morphological characters distinguishing T. gallica from the closely related species T. ramosissima, T. chinensis and T. canariensis are noted under Morphology, but it must be said that these are difficult to confirm in the field. T. parviflora is more readily distinguished by its four-part flowers, while T. aphylla is evergreen and has distinct foliage, the leaves not overlapping and strongly clasping the stem.
