Eriospermum dregei, IB13772



Fig.1 E. dregei, IB13772

The enation's shape and size are unusual for E. dregei. It is reasonable to hesitate at identifying it as E. dregei unless the taxonomic description is understood enough.

This is the most weird E. dregei in our collection. Enations of ordinary plants should keep the thickness more or less toward the tips, but they get simply tapered on this plant. The smallness of whole enation should be mentioned, too.
With all the unique appearance, every important aspect of the plant indicates that this plant should be E. dregei, such as the flower shape, the tuber shape and the mode of hair development as well as the pattern of enation development.
Ingo Breuer, the collector of these plants, seems to have abstained from identifying them as E. dregei, but we think they are the species.



Fig.2 Close-up of the leaf

The much branching habit may remind of E. cervicorne or other but the enation begins from a single trunk thus this should be E. dregei or E. paradoxum.






Fig.3 hairs on the enation

Several hairs develop from a point then give some stellate appearance. This feature is of E. dregei but not of E. paradoxum.






Fig.4 E. dregei, IB13772, Another plant

This plant has larger enation but still weird enough for the species.







E. dregei, IB13772 plants tend to wake up later and go domant eariler here. They grow more slowly than the other E. dregei plants but are a bit more resistant against rapid temperature change or mild drought.
