96 D. Prain — Some additional species of Convolvulacete. [No. 2, 



part of the Prome gathering thereof; and 3. Lettsomia cow/wsa = 1404/2 from 

 Prome as represented at Calcutta — i^art of the species now to be described. 



10 b. Lettsomia confusa Prain ; leaves ovate acute, base sub- 

 cordate OX' truncate, sparingly hirsute to nearly glabrous on both 

 surfaces, peduncles short, 1-3-fld., bracts \~l in. oblong obtuse ad- 

 pressedly strigose deciduous, sepals ovate-obtuse or sub-acute, longer 

 than the bracts, densely adpressedly strigose. Argyreia confusa Prai^i 

 Mss. 



VAR. typica ; peduncles glabrous usually capitately 3-fld., nearly 

 as long as the glabrous petioles.

 Collectors ! 



VAR. brevipes Prain; peduncles puberulous usually 1-fld., much 

 shorter than the pubescent petioles. 



Burma: Prome Hills, Wallich (Cat. u. J404/2 in part in Herb. 

 Calcutta) ! Pegu Yomah, in Eng forests, Kurz n. 1087 ! 



A slender climber witli glabrous branches. Leaves long petioled 1-3 in. by 

 ^-2^ in., acute or acuminate, petioles slender, in var. typica 2-21 in. long, in var. 

 brevipes 1—2 (sometimes even 4) in. long. Peduncles very slender, in var. typica 2 in. 

 in VAR, hrevipes 0-^ in. ; bracts herbaceous ^ in. across : pedicels 0-^ in. Sepals 

 i in., coriaceous, enlarging in fruit, accrescent. Corolla 1^ in externally setose, 

 white {Kiuifs Collector) or purple (Kurz). Stamens included. Fruit globose, pink, 

 J in. diam. 4-seedcd, pericarp thin, papery. 



A very distinct species with the facies of Lettsomia setosa var. minor, but with 

 a very different fruit which indicates a closer natural relationship to L. strigosa 

 than to L. setosa. That portion of Convolvulus multibracteatus Wall. (Cat. 1404) 

 which is not Lettsomia aggregata, seems nearly i-elated to var. hrevipes : it has a 

 very similar coi-olla and fruit but the leaves are obtuse with rounded bases, and the 

 bracts are very different, as is the shape of, and the tomentum on, the sepals. If 

 Lettsomia hracteosa is the same in reality as Convolvulus multibracteatus (Argyreia 

 tomentosa Choisy), that species must be removed from the group of species with 

 exserted stamens, and placed next to this plant, 



12 b. Lettsomia longifolia Coll. c^- Hemsl, Journ. Linn. Soc, 

 xxviii, 95 ; leaves narrowly oblong-lanceolate acuminate, base rounded 

 or slightly cuneate, glabrous except the midrib above, sparsely strigose 

 throughout beneath ; Leads few-fid., axillary shortly peduncled, bracts 

 largo oblong- lanceolate, persistent.

A large climber. Leaves 5-8 in. by f in., petiole |-f in. Peduncles ^-1 in , 

 hirsute; bracts obtuse or subacute, reddish-purple, strigose beneath 1-1 j in. long. 

 Sepals equal oblong-orbicular, -J-^ in., coriaceous, dark red within, glabrous. Corolla 

 H in. glabrous externally, dark purple. Fruit depressed, subglobose, dark red, 

 usually 2-seedcd, J- in. long, | in. diam, 



^ very distinct species ; most nearly allied to Lettsomia atropitrpurea.
