1. Leda subcordata, C. B. Clarke, n. sp. Nearly glabrous ; the 

 innovations and inflorescence minutely pubescent. Ste77i 1 to 2 ft. long, 

 divided, rambling, sometimes decumbent and rooting at the lower 

 nodes (then with smaller leaves). Leaves opposite, subequal; blade 

 3*5 by 1-5 in., elliptic, acuminate, entire ; base rounded or slightly cor- 

 date ; petioles 1 in. long. Panicles terminal on the slender branches, 

 and with few distant subsolitary flowers ; bracts and prophylla 

 minute. Sepals -125 in. long, linear. Corolla white, -5 in. long ; tube 

 straight, narrowly funnel-shaped. Stamens 2 ; anther-cells 2, parallel, 

 at equal height, rounded at base ; pollen 45 by 30 /a, with 2 stopples 

 and 2 longitudinal bands on either side each stopple. Style glabrate. 



Perak: King's Collector 970; S cor techini 95 ; Curtis S16S. 



This species is close to the Khasia L. debilis, C. B. Clarke sub Diantherd, in which 

 the flowers are in approximate, sessile, opposite pairs, forming long linear spikes. 



2. Leda obovata, C. B. Clarke, n. sp. Nearly glabrous ; the 

 inflorescence miniitely pubescent. Stem 1 foot or more. Leaves 

 opposite, subequal ; blade 5-5 by 2-25 in. obovate, with a very short 

 acumination, entire, with many rhaphides, long decurrent at base ; 

 petiole hardly "5 in. long. Panicle terminal, long-peduncled, with few long 

 linear branches ; bracts and prophylla minute ; the branches very narrow 

 thinly flowered racemes ; pedicels "06 in. long, or occasionally 2 to 3 

 flowers clustered. Sepals -125 in. long, linear, acute. Corolla ("yellow" 

 in Eidley's example) "5 in. long; tube straight, narrowly funnel-shaped. 

 Stamens 2; anther-cells 2, parallel, one placed at one-third of its 

 length below the other, rounded at base ; pollen ellipsoid with longitu- 

 dinal bands. Capsule (young) -7 in. long, with a linear stalk, pubescent. 



Perak: Scortechini (type of species). Selangor: Biclley 7592 (an 

 imperfect specimen; appears to match). 



This species is near Dianthera leptostachya, Benth. 



3. Leda (?) densifloba, C. B. Clarke, n. sp. Glabrous. Stems 8 in. 

 long, decumbent at base. Leaves opposite, equal, some 5 by 1 in., lan- 

 ceolate, some 5 by 1-5 in, elliptic-lanceolate ; nerves 7 to 8 pair, patent ; 

 rhaphides many, small on both surfaces ; margin undulate ; base cuneate 

 to a petiole "25 in. long. Inflorescence terminal ; peduncle '5 in. long ;
