THIS memoir, written five years ago, and alluded to on a former occasion *, describes a 
small group of plants marked by very peculiar characters. They are distinguished chiefly 
by the unusual growth of the calyx, which often increases in an extraordinary degree 
as the fruit advances to maturity; but they are more especially remarkable for the 
atropous development of their ovules and seeds. The group, consisting of the genera 
Auxemma, Sacellium, Hymenesthes, Patagonula, Paradigma, and Plethostaphia, may 
thus be characterized : —- 
AUXEMMEA. 
Tribus Совртлсвлком. Flores hermaphroditi. Calyx tubulosus, dentatus aut divisus, demum amplifi- 
catus. Corolla tubulosa. Stamina inclusa. Ovarium superum, disco carnoso hypogyno insitum, 
4-loculare : ovula in quoque loculo solitaria, erecta, et atropa. Drupa carnosa, vel subexsucca, mono- 
pyrena: pyren ossea, rugosa, 4-locularis, aut abortu 2-locularis: semen in loculo solitarium, struc- 
tura Cordie, sed omnino atropum. 
l. AUXEMMA. 
The type of this genus is a curious Brazilian plant found by Gardner, who regarded it 
as a species of Patagonula, and mentioned it in his * Travels,’ p. 159. Тһе flower, in 
structure, is not unlike that of the genus just mentioned, has a more tubular calyx, 
which becomes vastly inflated around the fruit, increasing to about 30 times its original 
length, and swelling proportionally. The drupe, which it conceals, is nearly of its length, 
and about the size and shape of a small damson, containing a hard scrobiculated nut, 
which is 4-сеПей ; its seeds distinctly atropous. The generic name is derived from avfw, 
amplifico, čupa, vestis, from the singular enlargement of the calyx. 
AUXEMMA, nob. 
Сайт parvus, tubulosus, membranaceus, ore 5-dentatus, persistens et in fructu valde amplificatus. . 
Corolla tubulosa ; tubus cylindricus, calyce dimidio longior, subplicatus, fauce vix ampliore ; /imbi lobi 5 
zequales, rotundato-ovati, tubum subzequantes, subexpansi, sestivatione introflexi, cum apicibus incur- 
vatis centro conniventes. Stamina 5, lobis alterna, inclysa, inequalia, tubo dimidio breviora; fila- 
menta tenuia, paulo supra basin tubi inserta: anthere ovate, 2-lobe, lobis filamento adnatis, rima 
laterali utrinque dehiscentibus. Discus hypogynus, carnosus. Ovarium superum, disco insidens, 
conico-ovatum, 4-loculare; ovula in loculis solitaria, e basi erecta, atropa: stylus brevis, ultra 
medium 2-fidus, ramis divaricatis bifidis: stigmata 4, oblique clavata, corolla inclusa. Calyz in
