SOUTH AMERICAN PLANTS. 1 il 



filaments broad and often dilated suddenly, being connected by 

 their bases upon a fleshy ring adnate to the base of the corolla ; 

 the style being generally shaped like an inverted cone, more or 

 less thick, and the fruit being a large oval berry, often used for 

 culinary purposes as a substitute for Tomates. They are gene- 

 rally tall shrubs, with large fleshy cordate leaves, emitting a 

 strong, unpleasant smell. This group consists of Cyjjhomandra 

 calycina^ physaloideSy sycocarpa^ lobata, diploconos, floribunda,

Por the second group, I propose to retain my generic name of 

 Pionandra^ which will include those species formerly designated 

 under the section Euthystemon, together with some others that 

 will be indicated below. This genus differs from Cyphomandra 

 in its lengthened, straight, erect, and narrower stamens, almost 

 rostrate at the summit below the apical knob, which bursts 

 obliquely in front, forming two bilabiate gaping pores; the 

 pollen-cells also burst below by longitudinal fissures ; it has like- 

 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 first volume of this work, 

 in plates 15, 16 and 17 of Dr. Sendtner in ' Flor. Brasil.' fasc. vi., 

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

 generic character of the genus Cyphomandra with a few omissions 

 will therefore remain as formerly designated by me under Pio- 

 nandra (as above referred to, i. 34), while that of the latter 

 genus, as now restored and modified, and of which I will add 

 another species with pinnatifid 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-partitu8, per- 

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

 laciniis 5 lanceolatis, subtenmbus, sestivatione mtroflexo-val- 

 vatis. Stamina 5 sequalia, erecta, stylo circumdantia ; Jila- 

 menta brevissima, complanata, in annulum brevem tubo corollae 

 adnatum imo connata ; anthera magnse, rectse, superne ros- 

 tratfe, 2-loculares, loculis elougatis ad connectivum parallele 

 adnatis, rima longitudinal! ssepe dehiscentibus, summo glo- 

 boso-capitatis, hinc antice poris 3 transversim et oblique val- 

 vatis valvibus bilabiatis latissime hiantibus. Ovarium ob- 

 lon"-um, 3-loculare, placentis carnosis utrinque dissepimento
