Hippeastrum puniceum (Amaryllidaceae), a new naturalized species in the flora of Angola.
This paper reports the occurrence of several populations of wild-growing H. puniceum, recorded during a botanical excursion to the province of Malanje, Angola. The plant was observed in full blossom on 13 October 2014, just at the beginning of the rainy season, when most vegetation was only beginning to resprout. Populations of H. puniceum were observed in 5 different uninhabited sites in the province of Malanje, along the 50 km long road from Lucala to Cacuso. The plant appears in recently burned grass savanna, probably as a result of fire set for the purpose of hunting and clearing. The plant appears solitary or in small clusters not exceeding 0.5 m in diameter and seems to be associated with Lippia sp.
