the tube of the corolla is 7 lines long, 23 lines in diam.; the border-segments 11 lines 
long, 3 lines broad, thick, fleshy, distinctly auriculated at the base, and so firmly con- 
voluted sinistrorsely that they are with difficulty unrolled: the stamens are 4 lines long; 
the urceolate disk is 1 line high, 2 lines broad; the globular ovary is 14 line in diam. ; 
the slender style is 4 lines long; the clavuncle, with its glands, is 2 lines long; the 2 
stigmata 1 line long, 3 line broad. The fruit, according to Aublet, is about the size of a 
citron, of a greenish colour when not quite ripe; it contains a single seed, as in Zschokkea 
and Zacmellia, the structure of which is unknown. 
A drawing of the above species, explaining its floral structure, with a figure of the 
fruit, are given in Plate II. 
3. Currrana MarTINIANA, nob. : ramulis crassiusculis, nudis, angulato-striatis, apice foliiferis, cicatricibus 
foliorum caducorum crebre signatis ; foliis hinc paucis, alternis, magnis, elongato-oblon gis, a medio 
utrinque sensim angustioribus, imo cuneatis, et in petiolo subbrevi decurrentibus, apice acutis, 
supra pallide viridibus, subnitidis, sparsim pilosis, in costa nervisque sulcatis, nervis venisque trans- 
versim reticulatis immersis, subtus pallidioribus, costa, nervis venisque prominentibus et paullo 
pilosis; petiolo dense piloso, limbo 30plo breviore: floribus plurimis in apice ramulorum dense 
congestis, pedicellis duplo, et calyce 4plo brevioribus; calyce ore integro, extus dense flavide 
et adpresse villoso, intus tenuiter sericeo ; corolla calyce duplo longiore, intus glabra, extus pilis 
densis flavidis adpressis retrorsis villosa, tubo calycis longitudine, limbi laciniis 6, tubo sequilongis, 
carnosis, oblongo-acutis, imo subcordatis, valde convolutis: staminibus precedentis, cum filamentis 
paullo longioribus; disco brevi, campanulato, crenulato, glabro; ovario minimo, depresse globoso, 
glabro, 2-loculari; stylo tenui stamina attingente, imo dense piloso, superne glabro; stigmate ei 
zequilongo, bifisso, lobis lineari-acutis, adpresse erectis. In Guiana: v. s. in herb. Mus. Brit. in

A species very similar in habit to the preceding, but different in many charac- 
ters. Its aggregated leaves are 15 in. long, 61 in. broad, on a thick villous petiole 
only 3 in. long: it has about 12 densely aggregated terminal flowers, upon short 
villous pedicels, 1 line long, growing out of a cluster of very short acute bracts: 
the calyx is 6 lines long, 3 lines broad, somewhat gibbous at base; the tube of the 
corolla is 5 lines long, its border-segments 5 lines long; the aciculated anthers 4 lines 
long, on filaments 13 line long, fixed to the bottom of the tube, and dorsally attached to the 
anther j line above its cordate base; the style, rising from a tuft of hairs on the summit 
of the ovary, is 33 lines long, is thickened above by a clavuncle 1 line long; the stigmata, 
13 line long, are lanceolate and erect: disk 1 line high, 2 lines broad; ovary depressed- 
globose, 3 line in diam., its 2 cells too minute to ascertain the number of ovules: several 
spiral threads were observed in the fleshy substance of the segments of the corolla. 
CERATITES. 
This genus, well elaborated by Dr. Solander, has escaped the notice of botanists, owing 
to the knowledge being only possessed by few of the rare books in the Banksian library, 
where the scarce work of Solander is deposited—a volume which minutely describes many 
‘rare Brazilian plants, well illustrated by several beautiful coloured drawings. Ceratites 
was founded on a single species, collected by him in Rio de Janeiro in 1768, the typical
