Discussion

Angadenia berteroi is known from Florida only by collections from Miami-Dade and Monroe counties. It is considered threatened in Florida.

B. Barrios and S. Koptur (2011) examined the breed­ing system of Angadenia berteroi and concluded that the low fruit set seen in natural populations may be due to a combination of self-incompatibility and low visita­tion by pollinators. Within the pine rocklands hab­itat dominated by Pinus elliottii, the abundance (but not flowering or fruit set) of A. berteroi has been shown to be correlated with habitat fragmentation and time elapsed since burning (Barrios et al. 2011).

G. E. Burrows and R. J. Tyrl (2013) reported that the milky latex of Angadenia berteroi causes irritation and reddening of the skin upon contact and increased mucus production by the mucosa of the digestive tract upon ingestion.
