naked at the apex, two-celled: Pollen-masses erect, attached by the 
base. Stigma blunt. Wight. 
This very distinct species of Ceropgcta flowered this summer (1833) 
in the Edinburgh Botanic Garden, where it had been received from the 
East Indies, under the name of C. dulbosa. It agrees with that species 
in having a tuberous root, a twining, succulent stem, in the leaves, and 
‘in the form of the corolla; but is at once distinguished by the corona, 
which equally separates it from every other species with which I am 
acquainted. I would take this opportunity of calling the attention of 
Botanists to‘the form of that organ, as affording the most permanent 
characters for distinguishing allied species in this Genus.—In some, its 
interior lobes are very long, while the exterior are reduced to a narrow 
margin, and these appear opposite the interior, as in C. bulbosa, acumt- 
nata, and tuberosa, Roxs., and in another East Indian species in my — 
Herbarium.—A second set has the exterior series in five distinct, ovate, — 
entire, or two-cleft lobes, alternate with the interior, the interior ones — 
more than twice their length, and hooked outwards at the point. To — 
this section, belong C. juncea, Roxs. C. Wightii, perhaps C. Lunda, © 
Watt. Pl. Rarior. and two undescribed species in my Herbarium.— _ 
In a third set, all the lobes are ligulate, the exterior double the number — 
of the interior, and nearly equalling them in length. To this section — 
belong C. elegans, Watt. in Bot. Mag. and two unpublished speeies in 
my Herbarium.—A fourth set has the interior lobes long and filiform, 
the exterior double their number, ovate, obtuse, and scarcely the le 
of the column of fructification. To this section belong one unpublished 
species from Nepaul, (C. Wallichii) Wicur in Herb. Royle, and per- 
haps C. longifolla, Wau. P). Rar. 
In all these, the exterior lobes are at least twice as long as the inte- — 
tior.—In the fifth section, the interior lobes barely exceed the column of 
fructification, and are about one half longer than the exterior. — To this 
section belong two unpublished species in my Herbarium, These are 
all that I have had an opportunity of examining with reference to that 
point.—The species so grouped, often differ very widely in other re- 
spects, thereby producing some very unnatural combinations. 
__ In these remarks, I have eniployed the terms erterior and méertor” 
_ Series of lobes of the corona, from ‘supposing that the terms outer and 
inner corona used by Dr. Brown in his character of the Genus (in the — 
_ Wern. Trans.) imply the presence of a double series of parts, or twovel* 
_ ticils, a structure which does not, I think, exist. The coronal appendage Fe 
_ 1s apparently a campanulate organ, often resembling in form, the limb oF = 
the corolla, the ligulate divisions of which represent the interior SeTeS 
of lobes, while the intermediate, ventricose portions represent the exte- —

of a single verticil of five leaves, the lamina of which ate more oT 
united, while the coste are each prolonged into an acumen. The act —
