Euphorbia.] cxxxy. evPmoRBrACEX. (J. D. Hooker.) 245 
a "pedicelled stamen without floral envelopes of any kind; anther-cells 
usually globose. Ferm. fl. a solitary pedicelled 3-celled 3-ovuled ovary, in 
the centre of the involucre, also without envelopes; styles 3, free or com- 
bined, simple or 2-fid. Capsule of 3 2-valved cocci separating elastically 
from a columella and dehiscing ventrally or both ventrally and dorsally. 
Cotyledons broad, flat.—Species about 600, in all climates but the very cold. 
_ The species of the Anisophylium section of this genus have been indefinitely multi- 
plied, and require revision with the view of testing the constancy of the characters 
by which so many of the New World species which to the eye are undistinguishable 
from Old World ones are distinguished. Important differences do occur in the sculptur- 
ing of their seeds and in tlie size aud form of the limb of the involucral glands, but I 
suspect that these have been much exaggerated, for in so far as the Indian species 
show, they are variable. Several species founded by Boissier on solitary unnamed 
Specimens of Heyne's seen in the Herbaria of Vienna, St. Petersburg, &c., and not 
compared with those of other Herbaria, are little likely to be good. Various specific 
names usually attributed to Roth, because the species which bear them were de- 
scribed by him in his ** Nove Plantarum Species," are really to be attributed to Heyne, 
as stated by Roth himself under each. Heyne was not a mere collector, but an 
excellent botanist. 
. , The section Ewphorbium again must be carefully revised with living specimens ; it 
1$ Impossible to frame specific characters of succulent plants from dried ones, or even 
to determine what are species and what varieties. 
It is unfortunate that Boissier omitted to consult the Wallichian Herbarium at 
the Linnean Society when monographing the genus for De Candolle's Prodromus; 
and still more so that several species of the Anisophyllum section have been so mixed in 
that fine Herbarium that it is difficult to quote their numbers with accuracy. 
There are very few Euphorbiaceew in Wight's own Herbarium which he presented 
to Kew, They were probably lent elsewhere for description and never returned. 
Sect. I. ANisoPnyLLUM. Herbs, rarely shrubby below, prostrate or 
ascending. Leaves all opposite, oblique or unequal at the base, stipulate or 
connected by a stipular line. Z»volweres solitary or cymose; glands 4-5, 
usually furnished with a membranous petaloid limb. 
,l. ELEGANTES. Usually erect dichotomously branching herbs, with leaves 4 to 
m, long. Involucres axillary, solitary, or 2-3 together; limb of gland conspicuous, 
often large.—Sp. 1-8. . 
2. HyPkRICIFOLLE. Erect or decumbent branching herbs or shrubs, with leaves 
i-fin. long or thereabouts. Involucres in axillary and subterminal cymes or crowded 
in the uppermost leaves, rarely of only 2-3 flowers; limb of gland usually conspicuous 
though small.— Sp. 9-16. 
- CHAMESYCER. Prostrate, rarely erect plants, with leaves 1~} in. long, rarely 
More. Involucres solitary, or in very short subsessile cymes, usually crowded along 
one side of the stem, or of short lateral branches; limb of gland of involucre 
scure or 0, except E. burmanica. —Sp. 17-21. 
Skcr. IL. EcPHonsIUM. Shrubs or trees (except 6. Rhizanthium) with 
eshy terete ribbed angled or flattened stems and branches. Leaves 0, or 
alternate, or the upper opposite ; stipules 0, or glandular or of prickles. 
Lnvolueres axillary or terminal; or in the forks, often sessile, rarely cymose, 
glands without a petaloid limb. 
4. TIRUCALIT. Erect shrubs or trees, with unarmed angled compressed or terete 
Dches, leafless or with opposite alternate or fascicled leaves. —Sp. 22-23. 
- DracaxTHIUM. Erect shrubs or trees, with stout angled ribbed or winged 
branches that are crenate or nodose at the angles or wings, and there provided with 
or 3 stipular prickles,—Sp. 24-29. 
: RmizawTHIUM. Stem reduced to a 
CYmose rarely solitary involucres.— Sp. 30-31.
