Discussion:

Some of the specimens cited above have small leaves representative of de Candolle's var. parvifolium. The variation in this character on certain individual specimens, however, is so great that it is not believed worthy of taxonomic segregation. The spikes on E-4127 are much shorter than is customary for this species. This character, too, is quite variable.
