find glued upon one sheet a specimen corresponding with the upper figure, and below it 
a loose leaf, as shown in the drawing; upon another sheet are two specimens, collected 
by Shakespeare, precisely similar to Aublet's upper specimen in the size and shape of the 
leaves, in the inflorescence, and in general character, leaving no doubt as to their spe- 
cific identity. Upon still another sheet there is a very distinct species, also collected by 
Aublet, with leaves of a very different texture, being much larger, more lanceolate, more 
_coriaceous, corresponding with the loose leaf in plate 10, evidently showing that Aublet 
had confounded the two species. The upper part of plate 10 therefore unquestionably 
represents the real type of this species, reduced to half its size; and to it belong the ana- 
lytical details of its floral structure, badly represented in figs. 1-7, which are magnified ; 
figs. 8 and 9 show the fruit in its natural size (perhaps yet immature) In these several 
specimens of Tontelea scandens, the slender branches are somewhat hexangular, ver- 
rucose, with axils 25-3 in. apart; the branchlets, divaricately opposite at right angles, 
are about 1 line in thickness, terete, smooth, the ultimate leaf-bearing branchlets being 
still more slender, with axils } in. apart; the leaves are 21-3 in. long, 14-11 in. broad, 
on a petiole 21-3 lines long; the axillary panicles are 14 in. long; but the terminal in- 
florescence appears as a lax spreading panicle 4 in. long and broad, consisting of four or 
six of the ultimate axillary panicles, from which the leaves have fallen away ; the panicle 
is dichotomously branched, with a much shorter branchlet in each dichotomy, all the 
branches being slender and quadrangular, the peduncle 9 lines, the branches 6-4 lines, 
gradually diminishing upwards; the flower, in bud, scarcely exceeds the quarter of a line 
in diameter; the sepals and petals are dark, fleshy, glabrous, the margins fimbriated 
with minute papille; the disk is fleshy, shortly tubular, its diameter four times its 
height; the stamens as in the generic character. The fruit, as shown by Aublet in its 
natural size, is globular, drupaceous, 2 lines in diameter, said to be unilocular, and to 
contain four seeds.

in acumen sublongum obtusum subito attenuatis, integerrimis, margine cartilagineo

ruguloso, limbo 12-plo breviore: panieulis corymbulosis, axillaribus et terminalibus, 
sæpe geminis, folio 6-plo brevioribus, dichotome ramosis; floribus minutis. In

It wil be seen from the above character how extremely different this species is from 
the preceding, in the shape of its larger leaves, which are entire, darker, coriaceous, and 
almost smooth (without reticulations), and shorter dichotomous panicles only twice the 
length of the petioles. . Its slender branches, half a line in diameter, have axils 11 in. 
apart; the leaves are 4-43 in. long, 14-13 in. broad, on a petiole 4 lines long, their
