11. Ipomcea.] 96. CONVOLYULACE.E. 



Burnt grass lands on the plateau ! Fl. May. An exactly similar form has been 

 CoUectecrin Oudh ! 



19. I. turpethum, Br. Syn. Operculina turpetluim, Manso ; Bana 

 etka, S. ; Pitohri, H. T Tohri, Beng. 

 A large climber but stems scarcely woody, narrowly 3-4-Aving'ed. 

 Lower leaves broadly ovate cordate, often 6" by 47", acuminate or 

 acute and apiculate, upper often oblong- obtuse and mucronate, 

 petioles "To-S", Avith crisped wings above on the loAver leaves. Flowers 

 white in 3-5-fld. cymes 2-3" long, including the pubescent peduncle, 

 with large oblong cuspidate sub-persistent pvibescent bracts -5-1" 

 long. Sepals ovate-oblong or broadly elliptic, "T-'TS" long, outer 2 

 subherbaceous very broad, 3 inner membranous, all enlarged, 

 hardened and often split in fruit. Corolla glabrous glandular, with 

 tube about as long as calyx and broadly campanulate limb l'5-2" 

 diam. Capsule Avith the exocarp longitudinally or irregularly splitting 

 (circumsciss according to some authors), leaving exposed the depressed 

 globose transparent 2-celled endocarj). Seeds 4-1 obovoid brown, 

 minittel}^ reticulate glabrous, "2" long. 



Not very common. Bettiah, Hierovi/mufl Singhhum ! Manbhum, Campbell I 

 Palamau, common about Garhwa ! Angul ! Fl., Fr. March-Dec. Perennial. 



Juice rather milky. Stems, petioles, leaves and inflorescence shortly pubescent 

 or downy or older parts .g-labrescent. Leaves -with 9-12 strong sec. n., of which 2-3 

 close to the base, all nearly reaching margin, then incurved, tertiaries somewhat 

 raised beneath, more or less scalariform, depressed above (when fresh). Pedicels 

 1-1-25". lengthening and stouter in fruit. Fruiting sepals often 1" across, brittle. 



The powdered fleshy root made into a paste is applied in rheumatism, Camp. 

 Soxbnrgh states that the l)ark of the roots is employed as a purgative. Watt states 

 that it is a well-known purgative under the name of Turpeth-root or Indian Jalap. 

 The Jalap of the British Pharmacopoeia is the resin ol)tained from the roots of 

 Ipomcea pui-ga, Hayne. 



Var. humilior. 



Herbaceous, trailing. Stems angled or with raised lines only, 

 pubescent. Leaves ovate to oblong-lanceolate, often subhastate, 

 l-2'5". Pediincles often only 1-fid., with one pair of pitbescent bracts 

 only. Corolla 2". 



Santal Parganas ! Bhagalpur, r//ow.><ow ! Near river banks. Fl. Dec. 



This is a much smaller plant and I doubt whether it would ever develop into the 

 larger form as it ajipeais to die down to the perennial root each year. It has been 

 collected in various parts of India. 



It has the characteristic small yellow resinous glands on the outside of the 

 corolla as in the larger form, and which curiously do not appear to have been 

 previously noticed. 



20. L carnea, Jac^. Syn. Argyreia superbiens. Cave {teste Gal. Herh.). 

 A large straggling shrub with very milky juice, ovate cordate 

 acuminate leaves, larger 6" by 4" to 8-5" by 6", nearly glabrous, and 

 large convolvulus-like pink flowers 3" long and broad. 



Very common in gardens in Chota Nagpur and sometimes used as a (very 

 inefficient) hedge. FL chiefly cs. 



I am not (luite sure of the'correct name of this shrub; it is called A, »plendevx at 

 the Agri-liorticultural Society's Gardens, but its certaiidy not that. It climbs when 

 given a chance but is usually cut back. Young twigs usually red. L. micio- 

 scopicftlly puberulous, sec. n. about 10 strong, of which 4 are close to base, 

 tertiaries scalariform, conspicuous. There is a gland each side at the base of
