Notes on Indian Botany. 515 



Obs. — The leaves of this species exceed a foot in length, by 

 about 3 inches broad, glabrous on both sides, ending in a fine 

 pointed acumen. The limb of the calyx seems cylindrical, 

 truncated, but those on my specimen are not in a good state 

 for examination, being all past maturity. It may therefore 

 belong to the cleft or dentate section. 



24. Lasianthus constrictus, (R.W.) Fruticose ramulis 

 terete, thicker at the joints, glabrous or with a sprinkling 

 of hair near the joints : leaves slightly coriacious, lanceolate, 

 tapering at both ends, sometimes a little unequal sided, 

 slightly crisped on the margin ; glabrous on both sides, ex- 

 cept a sprinkling of hairs on the veins : veins slightly promi- 

 nent, especially the costa, which in the dry plant forms quite 

 a ridge : stipules minute, pointed : flowers axillary, sessile, fas- 

 cicled : bracts minute, hairy : calyx limb dilated, 4-lobed, 

 constricted at the throat : ovary 4- celled. 



Hab. — Mergui, Griffith. 



Obs. — The constricted neck, and dilated limb of the calyx 

 of this species at once distinguishes it from all the others, in 

 other respects it is a well marked species ; the thickening of 

 the nodes at the origin of the leaves, the elongated form of 

 the leaves, which are fully 6 inches long by about 1 \ broad, 

 almost sessile, tapering to a point at both ends ; all mark this 

 as a peculiar species. I have not seen either corolla or fruit. 

 The unique constriction of the neck of the calyx at first 

 made me doubt its being a Lasianthus, but the venation of 

 the leaves, which is peculiar and characteristic in this genus, 

 leaves no doubt on that head. 



25. Lasianthus pauciflorus, (R. W.) Ramuli terete, 

 tomentose near the extremities, below frequently covered 

 with a pulverulent crust : leaves subsessile, elliptic oblong,
