This is the only species of Colea as yet cultivated in our gardens. It is better known 
than all the others ; and we are therefore enabled to settle its synonymy with tolerable 
accuracy. I have seen, at Paris, Commer son's specimens upon which DeCandolle founded 
his Colea ? Commersonii, and consider them to be in every respect identical with C. flori- 
bunda. Why DeCandolle placed C. Commersonii among the species with terminal flowers 
is difficult to say, since some of the specimens prove that the racemes grow out of the 
old wood. Sieber' s n. 284 from Mauritius, upon which DeCandolle founded his C. cauli- 
flora, I have examined in the Vienna Herbarium, and I find that it cannot be specifically 
separated from C. Jloribunda.

This new species has the habit of Colea Jloribunda, Boj. It is, according to Bernier, 
from 20-25 feet high. Leaves 1-1J foot long ; leaflets 4-5 inches long and 1J-2 inches 
broad. Bacemes often 8 inches, and corolla about 1 inch long. At once distinguished 
from C. jloribunda by its very long racemes and its (outside) glabrous corolla. 
3. Colea ptjrpubascens ; . . . . , ramis angulatis pubescentibus, foliis 3-7 -no verticil- 
latis 7-10-jugis cum impari, foliolis petiolulatis ovato-oblongis longe acuminatis basi 
attenuatis, petiolis, petiolulis nervisque inferioribus purpurascentibus, racemis abbre- 
viatis e caule ramisque ortis, calyce glabro, corolla extus velutino-scabrida, stylo 
superne villoso, fructu .... (v. sp. s.) 
Colea purpurascens, Seem. MSS. in Herb. Paris. 
Geogr. Distr. Ste. Marie de Madagascar (Boivinl) ; Nossi-be (Boivin !). 
Has the habit of Colea jloribunda, but differs in the pubescent branches, and pseudo- 
stipules, the purplish tinge of the petioles, petiolules, and veins of the under side of the 
leaflets, as well as in its villose style. It flowers, according to Boivin, from November 
to January. 
4. Colea discolor ; fruticosa ; ramis (angulatis ?) apice hirsutis ; foliis (verticillatis ?) 
7-jugis cum impari, foliolis brevi-petiolulatis oblongo-lanceolatis obtuse acuminatis 
subtus purpureis, racemis e caule ramisque ortis, calyce . . . , corolla . . . , ovario 
. . . , stylo . . . , fructu ...
