The following are the new species above alluded to. 

 1. Cestrum Organense (n. sp.) — glaberrimum, ramulis tereti- 

 bus ; foliis ellipticis, utrinque acuminatis, submembranaceis, 

 in petiolum basi tumidum subdecurrentibus ; racemis axil- 

 laribus, floribus subcapitatis, bracteis foliosis magnis oblon- 

 gis sessilibus, corollse fere longitudine ; staminibus insertione 

 barbatis, edentulis. — Rio de Janeiro, Serra Organensi,

This species approaches Cestrum bracteatum, (Link et 

 Otto, PI. Select. 1. tab. 6. Bot. Mag. 2974), but its leaves 

 are neither lanceolate nor pubescent, nor have they any 

 pseudo- stipules : they are 5 in. long, If broad, on a petiole 

 6 to 8 lines in length. The peduncles of the racemes are 

 from 2 to 3 in. long : the bracts are 6 lines long, 4 lines broad, 

 with ciliate margins ; the calyx is glabrous, tubular, 1 h ne 

 long, with 5 short, erect, ciliolate teeth : the corolla with a very 

 slender tube, swollen below the mouth, is 9 lines long, with a 

 rotate border, the margins of the lobes externally are tomen- 

 tous for one-third of their breadth on each side, which are 

 turned in during Aestivation, so that they adhere together by 

 these broad woolly surfaces : the included stamens are in- 

 serted above the middle of the tube, and arise out of as many 

 tufts of spreading hairs, the anthers are rounded, 2-lobed,
