FLORA OF THE SUNDRIBUNS. 
aS^ 
Free port ion of bracteoles much shorter than their cupular base ; 
carpe Is completely 2-locular throughout ; stipules medium, 
lanceolate ; flowers yellow with crimson eye, changing to brown- 
ish red ^ . . . • . . . tiliaceus. 
14. Hibiscus tortuosus Wall, (not of Roxb.). 
Estuary of the Hughli, Wallich (Catalogue n. 19''! 3 A : 1817)! 
This plant has only once been collected in an apparently wild state. It grows 
well in the Calcutta Gardens, where there are some old and large specimens. It 
has the habit, the pubescence, and much the appearance of H. tiliaceus, but has the 
large stipules and exactly the flowers of H. macroph yllus which is, however, a tree, 
sometimes of considerable size. The fruit, which forms freely, is curiously inter- 
mediate between the fruit of H. tiliaceus and H. macrophyllus. In S. tiliaceus 
the five carpels are each completely subdivided by accessory partitions into 10 
chambers j in H. macrophyllus the five carpels show no trace of such subdivision. 
In H. tortuosus there are partial dissepiments in each carpel. This inter- 
mediate character, with the fact that in the Calcutta Garden the seeds oi H. 
tortuosus are always abortive, gives rise to the suspicion that we may have here to 
do with a natural hybrid between H, tiliaceus, the common Bhola and H. macro* 
phyllus which, though not a Sundribun plant, occurs in Chittagong. In any 
case H. tortuosus should be looked for, more especially in the eastern parts.
