816 CXXII. EUPHORBIACE (PRAIN). | Cyrtogonone. 
15-20 rather distant slightly ascending lepidote branches, the lowest 
about 3 in. long, each bearing 3-7 cymes; cymes 3-7-flowered, on 
lepidote peduncles 14-24 lin. long; bracts ovate-lanceolate, lepidote, 
very small; pedicels lepidote, 2-23 lin. long. Calyx globose in bud, 
3-4 lin. wide, densely lepidote, at length 2-3-valved. Petals 5, or 
sometimes 6, white, orbicular, glabrous, contorted-imbricate, the first 
petal quite outside, the last quite inside. Stamens usually 27-30, 
occasionally in 6-petaled flowers more numerous; filaments free, 
glabrous, about thrice as long as the anthers; anthers erect in bud, 
dorsifixed, 2-celled; cells parallel, introrse, dehiscence longitudinal. 
Receptacular glands as many as the stamens, alternate with the 
filaments of the outer series and mixed with the others all over the 
convex receptacle; glands resembling abortive sessile anthers, keeled 
on the back below, hirsute with stellate hairs on their inner face and 
minutely emarginate at the tip. Rudimentary ovary 0. Female 
flowers and fruit unknown.—Crotonogyne argentea, Pax in Engl, 
Jahrb. xxxiii. 283.

Dr., Pax has already pointed out the difficulties attending the reference of this 
plant to Crotonogyne, with which it only agrees as regards its lepidote indumentum ; 
as now appears, the male petals of Crotonogyne are almost always united, not free as 
in Cyrtogonone. 
44. GROSSERA, Pax in Engl. Jahrb. xxxiii. 281. 
Flowers dicecious, dichlamydeous. Male: Calyx ovoid or globose, 
closed in bud, splitting into 2, less often 3, valvate lobes. Petals 5, 
contorted-imbricate. Stamens 17-23, several-seriate ; filaments short, 
inserted on an obovoid receptacle; anthers dorsifixed ; cells 2, parallel, 
introrse, connective rather broad ; base of receptacle surrounded by a 
ring of 5 extra-staminal glands alternate with the petals and with the 
stamens of the lowest whorl. Rudimentary ovary 0. Female: Calyx 
5-lobed ; tube short-campanulate, lined at the base by the disk; lobes 
coriaceous, orbicular, imbricate, with finely ciliate margins.and a marked 
thickened external ridge which does not reach the apex. Petals 9, 
oblong, contorted-imbricate, much longer than the calyx. Disk cupular. 
Ovary 3-celled, faintly 3-keeled, glabrous ; ovules in each cell solitary ; 
styles 3, erect and closely applied in bud, }-partite, smooth, later 
reflexed and with the arms slightly divaricate.. Fruit a pene ahi 
capsule.—Shrubs. Leaves alternate, petioled, penninerved, with 2 
prominent glands at the point of junction with the petiole, margim™ 
subentire or denticulate. Flowers small or very small, in ample 
panicles at the ends of the branches; bracts and bracteoles small.—
