Euphorbia.] ^ oxxxv. EvPHORBIACEX. (J. D. Hooker.) 261 
Stems many from the rootstock, 1-3 ft., leafy. Leaves rarely more than } in. 
broad, sometimes minutely 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. Aays5-9,long or short. Involucres 
about } in. diam., often hairy without ; glands reniform ; pedicelshort. Styles often 
nearly as long as the capsule, but variable in length. Capsule in. diam., subglobose. 
Seeds 51, in. long, broadly oblong-ovoid; caruncle small, flat.—After a very carefu 
examination I am unable to regard E. cognata as anything but a form of È. 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, Boiss. in DC. Prodr. xv. ii. 120. E. consanguinea,

40. E. Edgeworthii, Boiss. in DC. Prodr. xv. ii. 120; tall, robust, 
quite glabrous, leaves 2-3 in. sessile membranous oblong obtuse or acute 
ase rounded, floral broadly ovate, involucral 3-4 orbicular, involucres small 
Campanulate villous within, lobes ovate ciliate, capsule } in. diam. warted, 
seeds rugose. 
WESTERN 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 Er, pilosa, The only ripe seed is rugose, but it may be in a diseased con- 
ition ; the caruncle is minute and peltate. 
4l. E. micractina, Boiss. 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. 
Kasur, on Pir Panjal; Jacquemont, in birch woods. 
_ Root vertical, cylindric. Stems 6-8 in. Leaves gradually larger upwards, largest 
2 in. broad ; involucral 1} lines long. Rays j-j in. Styles connate at the base, 
2-fid. Capsule depressed-globose, warts conical. Seed 1} line diam., ovoid, caruncle 
depressed.—I have seen no specimens. Boissier, who likens it to a very diminutive 
orm Of E. Apios or dulcis, does not describe the glands of the involucre, but puts it 
' the same section as cognata (pilosa). 
42. B. longifolia, Don Prodr. 62; tall glabrous or sparsely hairy, 
leaves 1-4 in. coriaceous sessile linear-oblong obtuse or acute nerves obsolete,

Involuereg 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. Boiss. in DC.
