TEMPERATE and SUBTROPICAL HIMALAYA, and Plains of NORTHERN INDIA ; from

tan, Java, China, Japan, Philippine Islds. . . 
Annual, glabrous or sparsely hairy. Radical leaves numerous, 1-3 in. long, in- 
cluding the petiole, which is rarely as long as the blade, coarsely irregularly crenate- 
toothed. Flowering-stems numerous from the root, 2-10 in. long, leafless or with 
alternate spathulate leaves. Racemes 1-6 in., pedicels 1-3 in. Calyx in fruit 3-3 in. 
diam. Corolla i-4 in. long, blue. Seeds exceedingly minute, pale.— Roxburgh's 
Columnea tomentosa, referred here by Bentham, can hardly be this. r 
2. M. surculosus, Don Prodr. 86; runners rooting with opposite 
leaves, radical leaves obovate-spathulate coarsely crenate and often subpin- 
natifid at the base narrowed into a short petiole, pedicels mostly bracteate, 
calyx-lobes 4 as long as the tube short obtuse or subacute suberect in fruit.

In its ordinary state very different from M. rugosus in the shorter racemes, the 
often pinnatifid leaf-bases, bracts and calyx; but small specimens of eitber are diffi- 
cult to distinguish. The Nilghiri specimens are very small and dense, withont runners 
or bracts, but they have the short-lobed calyx of M. surculosus; they may prove 
specifically different. The figure in Wight’s Icones represents the calyx very incor- 
rectly. 
3. M. dentatus, Wall. Cat. 3914; runners 0, radical leaves long- 
petioled elliptic-oblong or ovate sinuate, pedicels bracteate, calyx-lobes $ the 
ength of the tube rounded ovate or triangular obtuse or acute suberect 1n 
fruit. Benth. Scroph. Ind. 27, and in DC. Prodr. x, 375.
