.'] cxxxv. EUPHORBIACE^E. (J. D. Hooker.) 261 



Stems many from the rootstock, 1-3 ft., leafy. Leaves rarely more than ! in. 

 broad, sometimes rniuutely serrulate towards the tip or along the whole margin ; 

 nerves numerous but obscure ; involucral bright yellow, always orbicular but some- 

 times pointed at the tip and with an acute base. Says 5-9, long or short. Involucres 

 about | in. diam., often hairy without; glands renifonn ; pedicel short. Styles often 

 nearly as long as the capsule, but variable in length. Capsule in. diain., subglobose. 

 Seeds -^ in. long, broadly oblong-ovoid ; caruncle small, flat. After a very carefn 

 examination I am unable to regard E. cognata as anything but a form of E. pilosa, 

 with the warts of the capsule usually, but not always, more developed. Boissier de- 

 scribes that of pilosa as smooth or sparsely and minutely tubercled. E. cornigera, 

 which he separates from cognata by the serrulate leaves, in this respect differs from 

 that plant as his own var. trigonocarpa of pilosa does from true pilosa. As to Royle's 

 E. cashmeriana, it is impossible to refer so wretched a figure with certainty to any 

 one species, but I have little doubt about its being this. Boissier's locality for 

 cognata of " Nubra (Edgeworth) " is a misreading; it is not a Tibetan plant. 



E. pilosa proper ; capsule smooth or minutely warted. I find specimens with 

 this character mixed with the following. 



Var. cognata ; rays often numerous, capsule with few or many small depressed or 

 larger conical warts. E. cognata, JBoiss. in DC. Prodr. xv. ii. 120. E. consanguinea, 

 Klotzsch in Sot. Eeis. Pr. Wald. t. 19. Tithymalus cognatus, Klotzsch 1. c. p. 66. 

 ? E. cashmeriana, Eoyle III. 329, t. 82, f. 4; Boiss. I. c. 



Var. cornigera ; leaves finely serrulate, capsule with conical warts. E. cornigera, 

 Boiss. I. c. 122. Kashmir, alt. 6500-8500, Jacquemont, &c. ; Murree, Fleming, &c. ; 

 Kulu, Edgeivorth. 



Var. myrtifolia', stems short decumbent or ascending, leaves $-1 in. elliptic acute 

 faintly serrulate. E. myrtifolia, Edgew. mss. Kulu, Edgeivorth. 



40. E. Edg-eworthii, Boiss. in DC. Prodr. xv. ii. 120 ; tall, robust, 

 quite glabrous, leaves 2-3 in. sessile membranous oblong obtuse or acute 

 base rounded, floral broadly ovate, involucral 3-4 orbicular, involucres small 

 campanulate villous within, lobes ovate ciliate, capsule in. diam. warted, 

 seeds rugose. 



WESTEEN HIMALAYA ; Kumaon, above Leetee, Edgeworth. 



I suspect that this is only a state of E. pilosa with broader leaves rounded at 

 the base. The specimen is a solitary one in fruit, having only one capsule, of the form 

 and size of E. pilosa. The only ripe seed is rugose, but it may be in a diseased con- 

 dition j the caruncle is minute and peltate. 



41. E. micractina, JBoiss. in DC. Prodr. xv. ii. 127 ; perennial, shortly 

 sparsely hairy, 'stems short erect, leaves minute alternate sessile uppermost 

 largest \ in. elliptic-oblong obtuse remotely crenulate floral equalling the 

 rays, involucral 3 ovate obtuse, involucre campanulate lobes ovate subciliate, 

 capsule depressed warted, seeds obsoletely granulate. 



KASHMIE, on Pir Panjal ; Jacquemont, in birch woods. 



Root vertical, cylindric. Stems 6-8 in. Leaves gradually larger upwards, largest 

 in. broad ; involucral 1 lines long. Rays |-| in. Styles connate at the base, 

 2-fid. Capsule depressed-globose, warts conical. Seed 1J line diam., ovoid, caruncle 

 depressed. I have seen no specimens. Boissier, who likens it to a very diminutive 

 form of E. Apios or dulcis, does not describe the glands of the involucre, but puts it 

 in the same section as cognata (pilosa) . 



42. E. long-ifolia, Don Prodr. 62 ; tall, glabrous or sparsely hairy, 

 leaves 1-4 in. coriaceous sessile linear-oblong obtuse or acute nerves obsolete, 

 involucral 3-4 orbicular or broadly ovate and apiculate, rays few short, 

 involucres campanulate villous within, lobes rounded villous, styles long 

 slender deeply 2-fid connate below the middle, capsule -} in. diam. covered 

 obscurely and sparsely with conical warts, seeds smooth. oiss. in DC .
