mcvansoest said:Maybe Baja can have a look at A.TDG for the respective descriptions.
You are right, the 2 plants can be distinguished by their size (somaliensis much larger) and the degree of branching in the inflorescence (somaliensis more branched). TDG has hemmingii as 8-10 inches (20-24cm) wide and somaliensis as 14-28 inches (36-70cm) wide. I think somaliensis also tends to offset less but that's more a trend than a useful feature to distinguish them. The two were lumped together as one species in 1984 but are listed separately in the book.
Here is my plant, about 10 years old, a bit limited in its 3 gallon (25cm) pot. It flowers continuously year round (a real performer in that respect).
