Of the two numbers cited by Berg in the protologue,no. 700 was cited by Amshoff as "tj^e," i.e., lectotj^e; presumably nos. 700 and1092 represent the same gathering; for an explanation of the numbering system usedby the Schomburgk brothers, see the introduction to this paper. Field Mus. neg.23416 represents the isotype at Geneva.

Discussion:

Myrciaria ehrenbergiana Berg, Linnaea 27: 321. 1856.

Aulomyrcia ehrenbergiana (Berg) Amsh., Rec. Trav. Bot. Neerl. 42 : 8. 1950.

Easily recognized by the subsessile, subcordate, oblong leaves, and 4-merous flowers with calyx-lobes pubescent within. The panicles are abundantly beset with small dibrachiate hairs, and the calyx-lobes, especially the two small outer ones, separate readily from the hj^anthium after anthesis. Known from but few collections.
