An annual, supposed to be a native of America, remark- 
able for the deep pits of its leaves, which, however, dis- 
appear entirely in the dried specimen. Our drawing was 
made at Mr. Colvill’s Nursery in March 1826. 
A twiner, with a filiform, round, smooth stem. Leaves 
on long stalks, smooth, impressed with numerous rather 
large pits, cordate, three-lobed; the lateral lobes being 
broad, acuminate, and resembling the halves of a larger 
lobe; the middle one being longer, narrower, and acumi- 
nate. Peduncles about 2-flowered, half the length of the 
petioles, with two or three small bractez at the apex. 
Calyx 5-leaved, unequal, smooth, the outer sepals smaller, 
and subulate at the end, the inner oblong and cuspidate. 
Corolla pale blue, much longer than the calyx, with a 
campanulate tube, which is longer than the limb. Stigma 
2-lobed, capitate. JL
