1894.] D. Praia — Some additional si)ecies of Convolvulacea?. 105 



entire on both surfaces sparsely hirsute with long strigose hairs ; 

 flowers axillary solitary, peduncles short, sepals narrow lanceolate 

 acuminate unequal externally pilose ; corolla narrowly infundib aliform 

 sparsely hairy externally; stamens included, filaments hirsute. 

 Burma; Shan Hills, 4,000 ft., common, Collett! 



An erect or ascending herb, 6-12 in. high, root fusiform; leaves IJ-SJ in. 

 Sepals J in. long. Corolla 2^-3 in, long, IJ in. across mouth. 



The sepals in fruit are reflexed, but the fruits themselves have fallen, and it is 

 not known whether they have been capsules or berries. The flowers are very like those 

 of Ipomoea oarlerioides, but the plant has the facies of a Lettsoinia rather than of 

 an Ipomcea. 



13 c, Ipomcea popahensis Coll. Sf Hemsl., Jotirn. Linn. Sac. xxviii., 

 97 ; leaves simple shortly petioled narrowly oblong lanceolate or some- 

 times linear apiculate, entire, on both surfaces sparsely hirsute with 

 short strigose hairs ; flowers axillary on short peduncles with usually 

 1, rarely 2-3 flowers ; sepals ovate-lanceolate acuminate or linear lanceo- 

 late, pilose externally as are the lanceolate bracts at the base of the 

 very short pedicels ; corolla narrowly infundibuliform sparsely hairy 

 externally ; stamens included filaments papillose. 



Upper Borma : on Popah Daoung, Gollett ! Shan Hills, near Boi 

 Tat, 3,000 ft., and at Meiktila, Gollett! 



A very slender twiner, leaves l|-4 in. long, sepals |-f in. long, |-i in. wide, 

 purplish ; corolla purple 2 in. long, 1 in. wide at mouth. 



This species also has flowers very like those of Ipomcea harlerioides. None of 

 the specimens have ripe fruits ; the largest unripe ones present are i in. in dia- 

 meter sub-globose smooth with a thin pericarp, which however shows no trace of 

 ultimate dehiscence. The plant suggests by its general facies that it may be a 

 Lettsomia, in which case it would come nearest L. harhata Clarke and L. Mastersii 

 Prain.
