 with a narrow reflexed purple papillose border. Durkart. in Ann. Sc. Nat.

Habit and stature of A. platanifolia, of which Duchartre suggests it maybe a 

 form, but no intermediates have occurred. Leaves very variable in size and pubes- 

 cence, largest 12 by 6 in., longest 16 by 4 in., narrowest (var. angustifolia, Duchart. 

 1. c.) 12 by 2 in., cordate base deep or shallow, petiole 1-2 iu. Cymes and perianth 

 much more villous than A. platanifolia. 



Var.? dilatata, lips of perianth greatly dilated -f in. diam. Kumaon, Slink- 

 worth ( Wall. Cat. 2707 B) ; alt. 7-8000 ft., Strachey $- Winterbottom. 



7. A, Cathcartii, Hook. f. ; branches petioles and leaves beneath 

 densely silkily villous, leaves rounded-cordate acute or ovate-lanceolate 

 acuminate, cymes and perianth densely villous with very long spreading 

 hairs, perianth bearded with long hairs, mouth very wide square with very 

 broad recurved lips fringed with long purple papillose hairs. A. saccata. 

 var. villosa, Herb. Ind. Or. H.f. fy T. 



SIKKIM HIMALAYA and KHASIA MTS. ?, alt. 2-^3000 ft., J". D. H. Sf T. T. 



Habit of A saccata, but leaves shorter broader with dense silky shaggy wool 

 beneath, and a very different perianth, the tube of which is far more dilated, with 

 a much broader square mouth. Capsule as in A. Faccata. A fiue drawing of this, 

 made by Mr. Cathcart's artists, represents so different a plant from A. saccata, that 

 it can hardly be a variety. 



8. A. Griffith!!, Hook.f. Sf T. in Herb. Ind. Or. ; Duchart. in DC. 

 Prodr. xv. 1. 437 ; branches glabrous with villous tips, leaves broadly 

 ovate- or orbicular-cordate acute densely tomentose beneath, flowers axillary, 

 perianth densely pubescent, tube above the sac abruptly dilated into a 

 hemispheric cup 3-4 in. diam. with erect margins. Aristolochia, Griff. 

 Notul. iv. 190, No. 1015. 



EASTEEN HIMALAYA; Bliotan, alt. 8000 ft., Griffith; Sikkim, alt. 7-9000 ft., 

 J. D. H. 



A tall climber. Leaves 4-6 in. long and often as broad, woolly but not shaggy 

 beneath ; petiole 2-4 in. Flowers apparently all solitary and axillary (extra-axillary, 

 Griffith) ; peduncle villous, 2-3 in., with one or two leafy bracts. Perianth uni- 

 formly closely pubescent ; sac ribbed and veined ; limb or cup " ochreous yellow with 

 radiating lines of clavate red warts, throat blood-red; tube yellow and spotted red 

 within/' Griffith. Capsules 7 inches long, shortly stipitate, twisted at the base, 

 with 6 strong ribs and as many deep furrows. Seeds orbicular, convex on one face, 

 concave with a median ridge on the other. A remarkable species. The extracts 

 translated from Griffith's Notula? must be accepted cautiously, the Latin not being 

 very intelligible. 



DOUBTFUL AND EXCLUDED SPECIES. 



AETSTOLOCfTlA SPECIES. Western Himalaya ; Chamba, alt. 5000 ft., Clarke. 

 A slender climber, branches puberulous, leaves shortly petioled, 4-5 by 1-1 \ in., 

 membranous lanceolate finely acuminate from a truncate or broadly cordate base, 

 basal nerves short. This flowerless plant referred to Aristolochia doubtfully by Mr. 

 Clarke, and I should think correctly, is far beyond the geographic range of any other 

 Indian species. 



A. THWATTESII, Hook. Sot. Mag. t. 4918, and under 5295, was erroneously sup- 

 posed to be a Ceylon species. Its native country is unknown.
