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



Var. reticulata Prain ; leaves thicker, secondary nerves beneath very 

 distinct. 



Perak : Larut, Kunstler n. 8544 ! 



The peduncles and pedicels of this plant are rather shorter than in L. pena7igiana. 

 The sepals thoagh as long are rather narrower, and the corolla — described by Kunst- 

 ler as " waxy white, pale blue inside " — is but two-thirds the length and only half the 

 width of that of L. penangiana. But the leaves hare exactly the sparse adpressed 

 tomentnm of the type and have the same characteristic glandular punotulation, 

 while the fruit — described by Kunstler as " rich jjink " — is indistinguishable from 

 that of L. penangiana ; so that this form, though very distinct, does not appear 

 to deserve more than varietal I'ank, 



21. Lettsomia? Kurzii Clarice. 



This plant is shown by Kurz's specimens to be Argyreia Eooheri Clarke. Mr. 

 Clai'ke had not an opportunity of examining the material from which Mr. Kurz des- 

 cribed his Argyreia xeyJanica {For. Flor. Brit. Burma ii., 215). That description is 

 not very clear and the three varieties recognised by Mr. Kurz refer, as the sheets 

 named by him in the Calcutta Herbarium show, to as many very distinct species ; vae. 

 populifolia is Argyreia Hookeri Clai'ke, and is ixot'= Argyreia populifolia Gaertn. ; VAR. 

 hirsuta is Argyreia venusta Choisy, and is iiot = A. populifolia var. hirsuta Thwaites; 

 VAR. peduncularis is Convolvulus peduncularis Wall., which is the Bam.e thing as 

 Lettsomia siklcimensis Clarke. 



22. Lettsomia CDRTisii Praw ; leaves large elliptic shortly acumi- 

 nate glabrou.s except for a few hairs on the midrib above, sparingly 

 hispid beneath, peduncles long, cymes compound subumbellate, bi-acts 

 deciduous, sepals coriaceous the three outer sparingly hirsute rounded, the 

 two inner deeply emarginate glabrous. Argyreia Curtisii Prain Mss. 



Malay Peninsula : Selangor at Kwala Lampar, Curtis n. 2158 ! 



Scandent ; branches brown glabrous. Leaves long-petioled 4-5 in. by 2|-3 in., 

 petioles 2-3 in. glabrous. Peduncles 4-10 in. brown glabrous, bracts deciduous, 

 cymes rather open, 2^-3 in. diam., 12-16-fld. Sepals j in. Berry ovoid, fleshy, f in. 

 by i in., the lower third only embraced by the calyx. Corolla not seen. 



A very distinct species, easily recognisable by its emarginate inner sepals. 



23. Lettsomia kunstleri Prain ; leaves petioled large elliptic 

 acuminate, quite glabrous above sparsely strigose-hirsute beneath ; nerves 

 more densely hirsute as are the petioles, peduncles and young branches : 

 bracts small linear-lanceolate hirsute deciduous, peduncles long, cymes 

 loose 12-20-fld., flowers small, sepals orbicular subequal, 3 outer pubes- 

 cent the others glabrous externally. Argyreia Kunstleri Prain Mss. 



Malay Peninsula : Perak ; Goping, Kunstler n. 732 ! Chanderiang, 

 Kunstler n. 5672 ! Kota, Wray n. 2856 ! Distrib. Sumatra. 



A slender climber " 50-80 feet long " (Kunstler). Leaves 3|-4| in. by 2-2J in., 

 glossy above (Kunstler), petioles 1-1^ in. Peduncles 5-8 in, pedicels i-|^ in., cymes 

 2-3 in. across, bracts | in., sepals ^ in. the outer, (originally hirsute) three ultimately 

 glabrescent. Corolla ^ in. or less, white outside, bright pink or red within, externally 

 hirsute. Berry ^ in. by J in., the lower fourth embraced by the calyx.
