MR. H. N. RIDLEY ON CYRTANDRACEH MALAYENSES., 499 
minate seeds lying, as it were, in a trough formed by the 
spreading of the sides of the capsule. 
In some species the base is broader (e.g., Didissandra 
quercifolia, Ridl., Didymocarpus cewruleus, Ridl.), and tapers 
gradually to the apex. During rain the drops of wet collect 
in the upper part of the trough and run down to the point, 
Sweeping the seeds before them, so that they are washed out 
of the trough and borne away over the rocks. As in most 
of the small-seeded rock plants of the wet jungles, the seeds 
are reticulate or roughened by processes, so that they adhere 
to the stone surfaces or in crevices, and are not washed down 
the streams and carried into the low country, as would be the 
case were they smooth and rounded. 
The Heterobea section of Didymocarpus (D. crinita, Jack, 
D. platypus, C. B. Clarke, &c.) are much more widely 
distributed, not only throughout the peninsula, but also beyond 
into Sumatra and Borneo. They usually inhabit the thicker 
jungles, where they grow upon the soil rather than on rocks. 
To sum up the distribution of the whole, as far as is known, 
of 72 species, no less than 53 are endemic, but five occur also 
in Burma and Siam, and 13 in the islands of the Malay 
Archipelago.
