198 Mr. J. Miers on the genus Pionandra, 



wise an elongated fusiform hollow style, with its small stigmatic 

 glands wholly included. The latter genus, on the contrary, is 

 remarkable for its thicker and shorter anthers greatly curved 

 upon a fleshy gibbous connective, and for its peculiar style, 

 which is generally short, thick, in the form of an inverted cone, 

 with large distinct stigmatic glands in its mouth : these peculiar 

 features are shown in plate 8 of the ' lllust. South Amer. Plants,' 

 in plates 1 5, 16 and 17 of Dr. Sendtner in ' Flor. Brasil.^ fasc. vi., 

 and in plate 227 of Martius, ' Nov. Gen. et Spec. Bras.^ The 

 generic character of the genus Cijphomandra with a few omissions 

 will therefore remain as fomierly designated by me under Pio- 

 nandra (lllust. South Amer. Plants, i. 34), while that of the latter 

 genus, as now i*estored and modified, and of which I will add 

 another species with pinnatiiid leaves (as in C.fraxinella, Sendt.) 

 collected by me in the Organ Mountains, may be summed up as 

 follows : — 



Pionandra, nob. (gen. reformatum). Calyx 5-partitus, per- 

 sistens. Corolla hypogyna, tubo brevi, limbo amplo 5'partito, 

 laciniis 5 lanceolatis, subtenuibus, sestivatione introflexo-val-
