 Sumatra. 



Wall. Gat. n. 1378 is exactly the same as authentic specimens of Lettsomia suma- 

 trana collected by Teysmann in Sumatra. Thougli the two varieties differ so 

 markedly in the shape of the corolla, the leaves, calyces, ovaries and caps ales are 

 identical. The corolla in the Malay variety is much as in the Indian, red purple 

 at the base, white streaked with pink near the mouth. 



42 &. Ipomoea nymphaefolia Bl., Bijdr. 719 [1825] not of Grise- 

 hacli [1866] ; leaves orbicular-ovate, shortly acuminate entire glabrous 

 on both surfaces or sparingly hairy on the nerves beneath, peltate with. 

 a rounded or slightly retuse base, the floral leaves more deeply cut and 

 at times cordate with a narrow sinus ; flowers large in loose cymes on 

 a common peduncle sometimes shorter than the petioles sometimes 

 longer than the leaves ; sepals broad obtuse coriaceous nearly equal ; 

 corolla wide campanulate glabrous externally ; capsule large. Ipomoea 

 peltata CTioisy, Conv. Or. 70 (1833) ; BG. Prodr. ix., 359 ; Miq. Flor. hid.

Pbrak : Pangkor, Scortechini n. 1074 ! DiSTRiB. Mascarene Islands 

 to Malaya, N". Australia and Polynesia. 



A tall woody climber ; leaves 6-10 in. by 5-8 in. ; Cymes 4-15-fld. ; sepals 

 glabrous f in. in flower, nearly 1 in. in fruit ; corolla 2-2^ in., yellowish-white with 

 red spots in the Mascarene Islands, yellow or white or purplish in Malaya, white 

 in N.Australia and Polynesia: anthers hirsute ; capsule 1 in. in diam. ; seeds pilose. 

 Ipomoea Grisebachii (I. nymphasfolia Griseh., Cat. PI. Cub, [1866], is not this plant. 

 The flowers in Rumphius' figures are much too small ; otherwise the description 

 and figures leave no doabt as to this being the plant intended. 



43. Ipomoea campanulata Linn. 



VAR. typica. Add to synonyms of F. B. I. : — Argyreia tiliaefolia 

 Kurz, For. Flor. Brit. Burma ii., 215., 7iot of Wight, and delete syn. I 

 campanulata Kurz, 1. c. 218. 



Kurz's Argyreia tiliaefolia, as his elaborate description and all his specimens 

 in Herb. Calcutta show, is Ipomrea campanulata Linn, which extends from South- 

 West Yunnan {Anderson !} a.n6 the Shan States (ifa?iders / King's Collectors !) to 

 Tenasserim. Argyreia tiliaefolia, a purely sea-shore species, is on the other hand 

 the plant described by Kurz, I. c, and named by him in Herb. Calcutta, Ipomoea 

 campanulata, though he has included in this species his specimens of Ipomoea 

 (Calunyction) glaberrima as well.
