 dehiscentibus. Stylus erectus, staminibus longiusculus, apice 

 incrassatus. Stigma 2-lobum, lobis oblongis, adpressis, intus 

 et marginibus recurvis glanduloso-viscosis. Ovarium conicum, 

 disco carnoso magno impositum, 2-loculare, placentis centra- 

 libus dissepimento adnatis, multiovulatis. Bacca; csetera ig- 

 nota. — Suffrutices Brasilienses, scandentes, glabra ; folia al- 

 terna, in ramis laxa, in turionibus florentibus fasciculatis, ellip-

1. Dyssochroma viridiflora. Solandra viridiflora, 'Sims, Bot. Mag. 

 tab. 1948; Link $ Otto, Ic. PL set. 101. tab. 47 ;— foliis el- 

 liptico-oblongis, utrinque attenuatis, glabris, petiolatis, deci- 

 duis ; floribus magnis, solitariis, calyce glaberrimo, corolla tubo 

 viridescente, limbo lurido-albescente. — Brasilia, Prov. Rio de 

 Janeiro, v. v. et s. in herb, meo et Hook. (Gardn. no. 502). 

 I found this plant growing at Tejuca and in the Organ moun- 

 tains : it is altogether glabrous : the stems are sarmentose, and 

 in the younger branches the leaves grow in dense fascicles, which, 

 as they fall off, leave them covered with crowded cicatrices, giving 

 them an areolate rugose appearance ; these terminate in a straight, 

 angular, smooth stem, covered with a shining bark that readily 

 peels off; the axils here are from 1| to 2 inches apart, and each 

 solitary petiole is articulated in a projecting cup, from which a 

 sharp ridge becomes decurrent on the stem below it ; the leaves 

 are 4^ inches long, 2 inches broad, on a channeled petiole ^ to 

 f inch in length ; the peduncle is J inch long ; the calyx 1^ inch 

 in length, \ inch diameter ; the corolla including the lobes, at the 

 period of opening, is 4 inches long, and when the segments are 

 coiled back, 2£ inches long ; the cylindrical portion of the tube, 

 J inch long, is included within the calyx, from which point it 

 becomes gradually funnel-shaped, and a little below the mouth 

 is somewhat ventricose, and about 1 inch in diameter, the lobes 

 of the border being 1^ inch in length and 5 lines broad at base, 

 these are marked by three parallel nerves which are continued
