Botany of the Tenasserim Provinces. 85 



Apocynece — Among several others, a curious genus occurs 

 with l-celled ovaria, the placentae being 2, and parietal ! The 

 same genus is remarkable for a monstrosity, in which the 

 hypogynous glands become largely developed, osseous, and 

 assume the form of stamina ; the true stamina being small 

 and abortive. 



Asclepiadece. — This order is rather numerously represent- 

 ed. Five species of Dischidia exist, among which is one 

 beautiful species with pink flowers ; the processes of the 

 corona staminea being rather incompletely formed. I would 

 beg to dedicate this to Dr. Brown, under the name of D. 

 Brunoniana. 



Finlaysonia obovata occurs abundantly, its stigma is re- 

 markable for having a deep transverse foveolus on each of its 

 flat faces, or on each of its faces opposed to the anthers. 



Loganiacece is represented by one species of Fagraea ; pro- 

 bably F. fragrans. 



Among Ehretiacece, there occurs a curious species of Ehre- 

 tia, with exceedingly long, prostrate, and rooting stems. To 

 the existence of this plant, the permanence of many of the 

 beds of sand, so numerous up the Mergui river, is to be attri- 

 buted. 



Verbenacem occur numerously. The placentae I find to be 

 either formed on the plan of those of Cyrtandraceae, or 

 Olacineae. To the former type, belong those with bilocular 

 ovaria, in which case cellular tissue is developed between the 

 plates. I believe, however, that many described as having 2- 

 locular ovaria have them in reality 1-locular. Among the 

 Burmese species, most have pendulous ovula. 



To the latter type, viz. of Olacineae or Santalaceae, belong 

 Congea and its congeners, which may be judiciously subdivi- 

 ded, and Avicennia. Congea has two incomplete septa, which 

 from their nearly reaching the placenta, may easily give rise 

 to the opinion of the ovarium being 2-locular.
