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



the writer quite agrees. Wliether it be accepted generally or not, it is certain that 

 any system of arrangement of the Convolvulacece which recognises Lettsomia as a 

 genns apart from Argyreia, must of logical necessity rehabilitate the various sections 

 of Ipomoea as separate genera. 



26. Sub-genus 1. Eulettsomia laxiflora Prain; leaves cordate 

 mucroaulate sparsely adpressed-liirsute, ultimately glabrescent above, 

 rather thinly grey-tomentose beneath ; peduncles long round -whifce; 

 tomentose ; corymbs many-fld. lax axillary or arranged in large terminal 

 panicles ; bracts small lanceolate obtuse deciduous, outer sepals ovate, 

 inner lanceolate rather narrower, all externally densely patently grey- 

 hirsute. Argyreia laxiflora Frain Mss.

Scandent, branches closely Tvhite-tomeutose ; leaves 1^-2^ in. long, 1-1^ in 

 across; petioles ^-liin., peduncles 2-4 in. ; corymbs 4-12-fld. pedicels ^— |- in ; 

 bracts ^ in. Sepah J in. long, outer \, inner ^ in. wide. Corolla f in., narrowly 

 tubular below campanulate above, purple, hirsute externally. Stamens exserted. 

 Capsule 3 in. red, as are the fruiting sepals within. 



This species is a member of the group to which Lettsomia aggregata {Argyreia 

 fi'jgregnta, Choisy), L. mysorcnsis, and L hellu belong. The corolla is exactly like 

 tliat of L. aggregata, tlie calj'x is almost like that of L. bella. From the former it 

 differs in having small bracts, from the latter in having long peduncles : from both 

 it is distinguished by its lax cymes. From L. vrijsorensis it is distinguished by its 

 inner sepals being as long as the outer.
