TROPICAL AMERICAN RUBIACE,^ 175 



patentes. Capsula inter minima obtuse costata, sparse griseo-pilosa, 

 cah'cis lobis aliquanto accrescentibus glabrescentibus coronata. 



Colombia : Province of Ocana, Crecenoche, 900 feet ; ii. Mav. 



A short erect unbranchecl herb — aj^parentlj annual. Leaves not 

 more than 4 cm. long and 1--1 cm. broad. 6'«/y^'-lobes, in the Hower, 

 2-5 mm. ; in the fruit, barely 4 mm. long. C(9ro//«-tube, 13-14 mm. 

 long, and over 2 mm. wide at the mouth ; lobes, 7 mm. x 5-2 mm. 



Allied to the Guianan >S'. pratensis, from which it di:ffers in the 

 sessile, oblong, non-acuminate leaves, the short, relatively broad calyx- 

 lobes, and the very small capsule, which is barel}^ 4 mm. long at 

 maturity. 



The types of the following species I have, unfortunately, had no 

 opportunity of seeing : — 



*S'. fjlomerata H. B. K. Nov. Gen. & Sp. iii. 398. K. Schumann 

 distinguishes this sharply from ^S. pratensis on the grounds of its 

 leathery corolla, tripartite external bracts, and lengthily acuminate 

 silk}^ leaves. He quotes Spruce 3665, fi'om Maypures, as an example. 

 It is probably a distinct species. 



aS'. trichantha Miq., in Linniea xviii. 293, is stated by the author 

 to have its nearest ally in *S'. glomerata H. B. K., from which he dis- 

 tinguishes it by the leaf-shape (" . • • intimis ellipticis reliquis lanceo- 

 latis ....'') and the corolla (" . . tubo longe villoso et simul breviore 

 certe sui juris."). The habitat is given as "in Surinamo copiose . . ." ; 

 and it would appear to be a form of variety of ;S'. pratensis, essentially 

 a Guianan species. 



S. vinca Mart, ex K. Sch. in Fl. Bras. vi. vi. 250, identified by 

 Schumann with S. pratensis, may be >S'. hispida. 



S. carnea Neumann in Kev. Hort. ii. ii. 445 (cum tab.) has been 

 referred to above. 



Cepiialanthus IX America. 



This genus of Nauclece, according to Haviland's excellent mono- 

 graph in Journ. Linn. Soc. xxxiii. (1897) 38, is represented in the 

 New World by live species, namely : — C. saUcifolius Humb. & Bonpl., 

 conlined to Mexico ; C. Savandi Cham. & Schlecht., native in Brasil, 

 Paragua}^ and parts of the Argentine ; C. pernvianus Spruce, and 

 C. hrevijiortcs Spruce, each represented by a single specimen from 

 Tarapoto ; and C. occidentalis L., widely distributed over India and 

 S.E. Asia, and over North America from Canada to California. 

 Haviland identifies a Cuban plant {Wright 2758) with this species, 

 and one^or two Mexican specimens also. I find, however, from an 

 examination of the material in the National Herbarium, that the 

 Mexican specimens are quite distinct from C. occidentalis. . The 

 following novelties have apparently escaped notice hitherto : — 



Cephalanthus Berlandieri, sp. nov. 



Frutex ramulis teretibus Isevibus gracilibus glaber. Folia 3-ver- 

 ticillata elliptica papyracea leniter acuminata apice subobtusa basi 

 cuneata breviter petiolata, venis secundariis utrinque 7 ; stipjulce mox
