 broadly ovate in some specimens outside our area. Petiole •25-'4" slender. Follicles

" A decoction of the root is said to he efficacious in extremely virulent tj'pes 

 of fever. It is somewhat poisonous," M. S. Bamaswami. 



2. T. asthmatica, W. 4" A. 



A twiner with subtomentose stems (in our specimens), oblong or 

 somewhat ovate-oblong apiculate leaves 2-4" long with rounded or 

 sub-cordate base, pubescent beneath. Petioles -4-1" long. Flowers

Orissa, Mahanadi delta ! Chilka Lake, Hooper ! Fl. May. Fr. Sept. 



The stems and leaves are variable in indumentum and some specimens are 

 glabi'ous in Bengal. Sec. n. .3-5. of which 1 is from base, usually looped and not 

 very strong. Cymes hairy. Cal.yx -2" with subulate-lanceolate hairy sepals. 

 Petals broadly lanceolate, obtuse. ' Corona very large, the processes forming a 

 closed ring with large round free lobes at base and free tips above finely acuminate. 



Roxburgh states that the roots form an effective substitute for ipecacuanha. 



3. T. longifolia, Wight. 



A species of TylopJwra collected bj' Campbell in Manbhum is so named in the 

 Cal. Herb., but the specimen is not in condition for satisfactory determination. It 

 looks to me more like T.fasciculafa, Ham. T. longifolia has quite glabrous lanceo- 

 late leaves 3-6" long with a cordate base and elongate cymes bearing small 

 distant umbels of small 3-ellow flowers on the very long rhachis. Sepals ovate. 



4. T. rotundifolia, Ham. 



A creeping somewhat fleshy herb Avith prostrate pubescent or 

 tomentose branches and opposite very shortly petioled elliptic or 

 orbicular or very broadly ovate leaves 2 -4" 5" which lie closely 

 appressed to the soil. Fls. •25-45" diam. on filiform pedicels 'S-IS" 

 long in peduncled umbelliform cymes. Follicles single broadly 

 lanceolate grooved on one side, 2"5-3" by 1" at the broadest part (a 

 little below the middle), somewhat compressed, glabrous, mth thick 

 fleshy walls. 



Sandstone Hills, N. Champaran ! Fl. May-July. Fr. Nov. -Dec. 



L. with sub-cordate base somewhat hairy or pubescent on the 3-5 strong sec. 

 nerves beneath, lowest from near base. Petiole •l-"2". Bracts at top of the short 

 or long peduncle very small and narrow, persistent pubescent. Cj'mes hairy. 

 Sepals^ linear-lanceolate, -15", hairy. Petals ovate. Coronal processes swollen 

 globose without free tips above. Seeds •25" brown narrowly winged, coma '8" 

 white caducous. 



The fruit is very unlike that of most in the genus. 



20. HOYA, Br. 



Twining or often epiphytic and pendulous with thick fleshy or 

 coriaceous leaves and often wax-like flowers in umbels. Corolla 

 rotate, fleshy or waxy, lobes often convex or spreading or reflexed, 

 valvate in bud. Corona, staminal, of large fleshy or horny processes, 

 stellately spreading or ascending, often concave on the upper surface,
