CONTRIBUTIONS TO BOTANY.

by Swartz upon two species so dissimilar in floral organization, 
in the size and form of the fruit, in their habit, and in the shape 
of their leaves, that he classed them together with great doubt. 
DeCandolle and other succeeding botanists have not attempted 
to disassociate them ; but when another species, closely allied to 
T. parasiticum, was flrst described by Miquel, he made it the 
type of a new genus, calling it Schlegelia lilacina. Prof. De- 
Candolle, however, expresses a doubt whether it be sufficiently 
different from Tanaecium to claim a generic distinction : this 
remark is true as respects T. parasiticum, which is certainly con- 
generic with it. Now, if we compare the drawings of Swartz of 
his T. albijlorum (FI. Ind. Occid. tab. 20) and of T. crudgerum 
(Plum. Am. tab. 254), on the one hand, with T. parasiticum 
(Sw. icon, cit.) and with T. [Schlegelia) lilacinum, Miq. (Aubl. 
Guian. tab. 254), on the other, no one can doubt that the two 
former species are generically distinct from the two latter. In 
the former group the plants are scandent, their leaves conjugate, 
with a long cirrhus, as in Bignonia-, the calyx is green, long, 
and tubular ; the corolla is white, pubescent within and without, 
with a very narrow hypocrateriform tube, of unusual length (6 or 
7 inches), with an undulately crispate 5-lobed border ; the sta- 
mens and style (of great length) are exserted ; the anther-lobes 
are linear, widely divaricated, with a terminal excurrent connec- 
tive ; the fruit is very large, oblong, often a foot in length; and 
the seeds are large, broad, compressed, and not imbedded in pulp. 
In the latter group the stem is radicant ; the leaves are quite 
simple, as in many of the Catalpece ; the calyx is coloured, short, 
and globosely campanulate ; the corolla is deep violet or purple, 
quite glabrous, scarcely more than | inch long, much swollen 
and ventricose above a short basal constriction, with an oblique 
bilabiate border, the upper lip of which is erect, bifld, scarcely 
cleft to the base, and the lower lip is trifid, refleeted, with the 
middle lobe considerably the largest, and enveloping all the 
others in aestivation ; stamens and style only half the length of 
the short corolla, and of course included ; anthers very small, 
ovate, white, with nearly parallel lobes ; fruit globose, only | inch 
diameter in one species, and not more than ^ inch in the other, 
with projecting seminiferous placentae, rendering it falsely 2- 
locular, as in Kigelia, and containing numerous minute, angular, 
oblong seeds enveloped in pulp. These characters are severally 
as opposite as possible, rendering it evident that Schlegelia is not 
only generically distinct from Tanaecium, but appertains to a 
different family. The former genus manifestly belongs to Cres- 
centiacece, while Tanaecium will probably find its place near Ade- 
nocalymna in Bignoniece, because it possesses a similar habit, has
