means of ocean currents. Taking into account also the littoral 

 habitat of D. spathacea, and the considerable distances oversea 

 separating various parts of its area of distribution, it seems not 

 unlikely that ocean currents may have played some part in the 

 wide dissemination of the species, although direct evidence of 

 this is up to the present lacking.

When in a flowering state D. serrulata bears a strong resem- 

 blance to D. spathacea , and has been referred to that species. 

 This may perhaps account for the inland distribution in Burma 

 attributed to T). spathacea (SpatJiodca Rheedii) by Kurz, who 

 says that it is " not unfrequent in the lower and upper mixed 

 forests from Prome and the Pegu Yomah down to Tenasserim " ; 

 but is is possible that the area of the two species overlap. Gage 

 has recorded D. Rheedii as one of the more common and con- 

 spicuous trees in the fairly open deciduous forest covering the 

 Nwamadaung range, Minbu District, Tipper Burma; but it seems 

 possible that the tree in question will prove to be D. serrulata. 

 (Bee. Bot. Surv. India, vol. iii. p. 86), 



The capsules of D. serrulata strongly resemble those of 

 Stereospermum, so that, in the absence of flowers, it was formerly 

 assigned to that irenus.
