192 Mr. J. Miers on the genus Ectozoma. 



although its flowers are much smaller, they agree in having a 

 fleshy tubular corolla with five short lobes, which are imbricated in 

 aestivation. They present the unusual character of the insertion 

 of the stamens upon a free perigynous ring, as in Triguera, but 

 with the peculiarity of being adnate upon its external face ; hence 

 the derivation of its generic name, from i/cros, extra, and Jwyua, 

 cingula. In most cases where the stamens spring from a perigynous 

 ring, the filaments originate from its inner face, as in Salpichroma, 

 or from its margin, as in Triguera ; but we have a somewhat ana- 

 logous case in Campanula medium, where the filaments are di- 

 stinctly adnate upon the back of the large, broad processes, that 

 form the fornix around the base of the style, peculiar to that 

 genus. Its generic features may be characterized as follows : — 



Ectozoma (gen. nov.). — Calyx campanulatus, brevis,crassus,sub- 

 sequaliter 5-dentatus, dentibus triangularibus, erectis. Corolla 

 breviter tubulosa, medio subinflata, crasso-carnosa, limbo 5- 

 lobo, lobis suborbicularibus, aestivatione imbricatis. Stamina 5, 

 sequalia, inclusa, filamenta brevissima, compressa, e dorso an- 

 nuli perigyni liberi tenuis margine ciliati orta. Antherce ob- 

 longse, imo subcordatse, apice mucronulatse, lobis coriaceis con- 

 nective dorsali lineari parallele adnatis, margine longitudina- 

 liter dehiscentibus. Ovarium obovatum. Stylus erectus. Stig- 

 ma fere exsertum, globosum, sub-2-lobum. Fructus ignotus. — 

 Suffrutex Ecuador ensis, glaberrimus, subscandensh, folia alterna, 

 ovata, vix acuta ; inflorescentia paniculata, terminalis. 



1. Ectozoma Pavonii; — glaberrima, ramulis compressis, suban- 

 gulatis, epidermide rimosa ; foliis late ovatis, basi apiceque ob- 

 tusiusculis, vix acutis, crasso-coriaceis, supra impresso-punc-

 tiaco, piloso, pilis brevibus articulatis ; corolla carnosa, auran- 

 tiaca, glabra, limbi laciniis crassiusculis. — Guayaquil, v. s. in

This plant bears much resemblance in its habit to Juanulloa 

 and Sarcophysa. Its branchlets are much compressed, covered 

 with a shining peeling bark; the leaves are 5 inches long, 3^ 

 inches broad, on a thick channeled petiole of half an inch in 

 length. Its paniculate branching raceme is about 2 inches long, 

 each pedicel is 1 line long ; the calyx, 4 lines in length and 3 lines 

 in diameter, is very fleshy and rugosely pilose, and is divided to 

 one-third its length into five equal erect teeth ; the tube of the 

 corolla is 3 lines long, and the circular lobes of its border 1 line 

 in diameter, the tube is somewhat narrowed at its base and in the 

 throat ; the antheriferous free ring arises in the constriction of
