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 
estivation. 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 éxros, extra, and fapa, 
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 Sin 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 :— 
Ecrozoma (gen. nov.).—Calyx campanulatus, brevis, crassus, sub- 
eequaliter 5-dentatus, dentibus triangularibus, erectis. Corolla 
breviter tubulosa, medio subinflata, crasso-carnosa, limbo 5- 
lobo, lobis suborbicularibus, eestivatione imbricatis. Stamina 5, 
eequalia, inclusa, filamenta brevissima, compressa, e dorso an- 
nuli perigyni liberi tenuis margine ciliati orta. Anthere ob- 
long, imo subcordatz, apice mucronulatz, lobis coriaceis con- 
nectivo 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, subscandens? ; folia alterna, 
ovata, vix acuta ; inflorescentia paniculata, ter minalise 
Ectozoma Pavonii ;—glaberrima, ramulis compressis, suban- 
gulatis, epidermide rimosa ; foliis late ovatis, basi apiceque ob- 
tusiusculis, vix acutis, crasso-coriaceis, supra impresso-punc- 
tulatis, venis insculptis, subtus pallidis, venis prominentibus, 
petiolo crasso canaliculato ; racemis paniculatis, 2-3, termi- 
nalibus; floribus breviter pedicellatis, calyce carnoso auran- 
tiaco, piloso, pilis brevibus articulatis ; corolla carnosa, auran- 
tiaca, glabra, limbi lacinuis 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, 33 
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
