90 D. Prain — Some additional species of Convolvulacese. [No. 2 



VAR. typica. Add to localities of F. B. I. : — 



Burma : Karen Hills, Mason ! Shan Hills Collett ! Pegu Yomah, 

 Kurz ! Andamans : Coco group, Prain ! Malay Peninsula : Perak, Scorte- 

 chini ! DiSTRiB. : China. 



VAR. obtusifolia. Add to localities : — 



Andamans : Port Blair, very common ; E. H. Man ! King's Collectors ! 

 This species, nearest to A. splendens, is well distinguished by the marks indicated 

 by Mr. Clarke. 



The two varieties are perhaps hardly separable, the original specimens of 

 A. Championi, from Hongkong, which is not separable from Wallich's Convolvulus 

 ohtectus, being intermediate as to form of leaves between the two. The leaves in 

 the first variety (which includes here all forms with acute leaf-apices) vary in size 

 from 3 by li in. (in Wallicli's), or 3 by 2 in. (in Beutham's) original sijecimens, to 8 by 

 3| in. in some of Kurz's (from the lower part of the plant) in Pegu specimens, and 

 in shape from elliptic-oblong (which is usual) to sublauceolate in some from Tenas- 

 serim {Gallatly, 557) and Kedah {Curtis, 2582). In Gallatly's specimens, however, 

 leaves of the usual type occur on the same branch with the narrow ones referred 

 to. The base, moreover, which is usually cuneate is sometimes rounded, especially 

 in the Pegu, the Karen, and some of the Tenasserim specimens ; but the same 

 branches bear leaves of the ordinary type. Similarly, in the Andamans, branches 

 of VAR. ohfusifolia (which here includes the forms with apices of leaves obtuse) 

 bear at the same time some leaves with acute tips. 



Both varieties vary in degree of tomentum, especially on the upper surface : 

 those from Pegu, the Karen Hills, the Coco-group, and some, but not all, from 

 Tenasserim and the Andamans being glabrous above ; the others (including both 

 Wallich's & Beutham's types) are spai'sely hirsute. The tomentum beneath is 

 usually brown, but is grey in the Hong-Kong plant, and in that from the Pegu 

 Yomah. This closely resembles in flowering calyx and in foliage Anjyreia ? mollis 

 Choisy, from Java, and from Sumatra (Toysmann, n. 4332, Hort. Bogor.) which has, 

 liowever, a very different calyx (sepals sub-connivent) in fruit.
