DESCRIPTION OF THE SPECIES, COLOGANIA PULCHELLA. A slen- 
der twiner with the habit of a Kennedya. Stems when young, clothed 
with appressed hairs, nearly smooth when old. Stipues. small, 
linear subulate. Leaves alternate FoorsTacxs from one and a half 
to two and a half inches long with appressed hairs. LeaFr.ets three, 
one terminal, and two opposite, from a quarter to half-an-inch below 
the terminal one, all of them borne on very short partial footstalks, 
oval oblong, mucronate, rounded or slightly heart-shaped at the base, 
an inch to an inch and half long, with scattered appressed hairs on 
both sides, especially on the under side, which is of-a pale glaucous 
hue. STIPELL# very minute. FLOowers axillary. PepuNncLes very 
short, apparently none during the flowering, but often attaining half 
an inch or more as the fruit ripens. Prpicexs very short, fascicled. 
Bracts and bracteole small, subulate. Catyx five or six lines long, 
green, hairy; the lateral teeth about half the size of the upper one, 
the lower ones rather longer, but smaller, than the upper one, each of 
them terminating in a point. Sranparp purple with a white spot at 
the base, about half an inch long and broad, besides the claw which 
is contained in the calyx. Wunes of the same colour as the standard, 
much narrower and shorter. Keex still smaller, of a pale colour. 
Pop an inch long or rather more, hairy. 
Poputar anp GeocrapuicaL Notice. The enormous extent to 
whieh recent discoveries have carried the order of Leguminose, renders 
their classification and distribution into tribes and genera a matter of 
no small difficuliy; no order contains, perhaps, a greater number of 
extensive genera, differing from each other by very slight characters; 
in none has it been found more essential not only to rely in a great 
measure on the fruit in the distinction of the genera, but even to call 
in the aid of the vegetative organs, the leaves, stigmas, and bracts, for 
the demarkation of the larger groups. Linnzus, indeed, considered 
the pod to be of little importance, and added, “ nec folia pro charac- 
teribus unquam assumi debet,” but in his days searcely six hundred 
Leguminose were known, whereas, if all those now published, or lying 
ready for publication in our large herbaria, were reckoned up, the 
number would be found not to fall far short of six thousand. 
When Decandolle, in the preparation of his Prodromus, arrived at 
. this beautiful order, he was induced to bestow special pains upon it, 
and with his master mind grasping and digesting all that had till then
