86 Botany of the Tenasserim Provinces. 



Among Lentibulariae, a small species of Utricularia exists, 

 which is found growing among moss on damp walls, and 

 rocks ; it is furnished with bladders. 



Plumbaginece are represented by Plumbago and ^Egialitis 

 rotundifolia. 



One species of Cycas, one of Coniferce, and Agathis lo- 

 ranthifolia exist in the flora. 



Of Gnetacece, three species exist, Gnetum gnemon, scan- 

 dens, and an erect one, which I have in my account of Gne- 

 tum called G. Brunonianum. 



Burmannia are represented by Burmannia, of which three 

 species occur ; of these two are aphyllous and parasitical, 

 one being entirely of a deep blue colour, the other entirely 

 white. These, as well as the aphyllous Salomonia with which 

 they are associated, throw considerable light on the seeds 

 of parasitical plants, and prove that this peculiar manner of 

 growth is not necessarily connected with a peculiar formation, 

 or rather deformation of the embryo. Salomonia parasitica 

 has the usual form of embryo, while the whole three species 

 of Burmannia have no other embryo than a grumous divided 

 mass. This fact proves, I think, that no very great stress is 

 to be laid upon the existence of these anomalous embryos, the 

 study of whose germination will prove highly interesting. 



This structure of the seeds will probably suggest new ideas 

 as to the affinities of the order which it composes. 



Orchidecs form about one-twentieth of the vegetation ; 

 subsequent researches will, I think, increase the ratio consi- 

 derably. 



Apostasies (Lindl.), are represented by one species, pro- 

 bably A. nuda.
