Notes (Last Modified On 3/11/2009)

general taxon notes:

Calymperes erosum is well marked by its reddish gemmae borne in a ball-like cluster all around on the tip of the excurrent costa and by the distinctive mammillose distal cells of its cancellinae. The latter alone will distinguish it easily even when gemmae are lacking, although then the excurrent costa from which gemmae have dehisced is still distinctive. The mammillose cells may be lacking at the very tips of the cancellinae but can be found along the sides of the cancellinae just proximal to their tips. The only other Chinese Calymperes with gemmae borne all around the tip of the excurrent costa is C. tenerum, which lacks teniolae and has plane distal cancellinae cells. The species most often confused with C. erosum is C. afzelii, but C. afzelii has the distal cells of its cancellinae plane and bears gemmae only on the adaxial surface of its costa tip, which is never excurrent. Some plants of C. erosum have the leaves all or mostly broad and nongemmiferous and may look very different from plants with the leaves all narrowly acuminate and gemmiferous. Calymperes erosum has previously been known in China under the name C. hampei Dozy & Molk., a synonym (cf. P.-J. Lin & Reese 1988).
