underneath, was found in November at Usui growing up with last year’s plant, which was іп seed. The 
flowers were purple. The seed-vessel had four divisions; and the seeds were covered with a mass of white 
silky fibre 4 inch long, but of no strength.—J. A. G.] 
Plate LX XX. fig. 1. Base of corolla-tube, showing insertion of the stamens, 
14. IPOMÆA,sp.? Leafy specimen only. Leaves rotundate in circumscription, deeply 
divided, the lower segments from the base of the lamina, the upper from the middle of the 
midrib ; segments broadly linear, acute, broadly crenate-undulate when pressed flat, the 
tissue between the lateral veins of each segment being remarkably bullate ; glabrous above, 
with thinly scattered hairs on the neuration beneath; petiole pubescent. It may be 
related to the foregoing species. 
Над. 5° 26 8. lat., 33° E. long. But a single specimen observed, Col. Grant ! 
[A climber, with handsome leaves indented underneath. Budsin January at Tura, 6° 26'S. lat. Purple.

Hab. Banks of Nile, Unyoro, Nov. 1862, Col. Grant ! 
А variable plant, both in form of leaves and number of flowers to each peduncle, if we are right in 
including the African specimens, from various parts of the tropics, in the same species. If Klotzsch’s 
two species described in Peters's Mossamb. Bot. 242-3 are to be maintained, Col. Grant’s plant may belong 
to one of them.

leaves of the Usui specimen are conspicuously sinuate-lobate. 
[No. 1 found on the slopes of Usui at 2°42! S. lat., alt. 4200 feet, with erect, bell-like, white flowers and 
velvety silvery leaves; Хо. 2 was common near huts іп Chopeh at 1° 40! N. lat. (November).—J. A. G.]

Notwithstanding the apparent absence of а dissepiment in the 
and very near to E. nummularius, L., of Tropical America, 
ovary, this plant must be an Evolvulus,
