592 PHANEROGAMIA. 



The imperfect specimen, without petals or stamens, accords very 

 well with a fruiting one from Sellow's collection, distributed from the 

 Royal Berlin herbarium, under the name of " Oxymeris pulchra, 

 Cham.;" a species which I find nowhere published. Our specimen 

 has the ribs of the leaves more bearded underneath, and similar 

 bristly hairs occur on the petioles, and sparingly on the branchlets. 

 It is related to O. alpestris, Gardn., but distinct. Perhaps it may not 

 be distinct from Oxymeris ciliata of Martius; which, it may be 

 remarked, cannot bear the name of Clidemia Martii, given it by 

 Nandin (in Ann. Sci. Nat. p. 375), since he has already a C. Mar- 

 liana in the same volume, p. 340.

Hab. Organ Mountains, Brazil. 



A slender flowering branch, of an apparently herbaceous and diffuse 

 plant, entirely glabrous, except some minute resinous-like atoms on 

 the angular brancldets and other new parts. Leaves membranaceous, 

 obovate or oval, 2 or 3 inches long, abruptly and conspicuously acumi- 

 nate, tapering at the base into a petiole of 5 to 10 lines in length, dull, 

 paler beneath, very entire, triplinerved above the base a considerable 

 distance, and with a slender sidimarginal nerve on each side ; the 

 transverse veins not prominent: the leaves of each pair somewhat 

 unequal. Panicle terminal, small and simple, with slender spreading 

 branches, loosely-floxvered ; usually three flowers at the extremity, the 

 middle one subsessile, the lateral short-peduncled. Bracts minute, 

 subulate. Floiver-buds 2i lines long, fusiform, much acuminate. 

 Calyx turbinate, rather oblong, slightly puberulent, the truncate 

 margin furnished with 5 very short callous teeth, apparently destitute 

 of internal appendages. Petals subulately long-acuminate from a broad
