836 CXXII, EUPHORBIACEA (PRAIN). | Chrozophora. 
Also in Egypt and in Palestine. 
As has been pointed out by Schweinfurth and by Miiller the two plants here 
included under C. plicata, A. Juss., are distinct in appearance and are easily 
separated. We follow Miiller in considering them varieties of the same species; 
Schweinfurth, who at first treated them as specifically distinct, has accepted this 
view. The typical C. plicata (Croton plicatum, Vahl) appears to be the more usual 
form in dried up pools and stream beds and on sandbanks in rivers; the variety 
obliquifolia (Croton obliquifolium, Vis.) appears to be usually met with as a weed 
in fields. The species has been also recorded by Pax (Ann. Istit. Bot. Roma, vi. 
183) from Ogadon (Robecchi, 372) and the River Ganane (Riva, 749/632). In the 
absence of muterial it is not certain to which of the two varieties these Abyssinian 
specimens belong. To this species also belongs Lepidocroton serratus, Presl, which is 
described as having 15 stamens, but in the absence of the type (which seems to have 
disappeared) it is impossible to say definitely which of the two varieties described 
represents Presl’s genus. 
2. C. oblongifolia, A. Juss. ex Spreng. Syst. Veg. iii. 850. A 
much-branched undershrub, with stems stout and woody below, but 
sometimes herbaceous and dying after flowering in the first year; 
stems rather harshly white or tawny stellate-pubescent. Leaves 
distinctly petioled, ovate-rhomboid or oblong to lanceolate, obtuse, base 
cuneate, narrowly notched, 2-glandular, margin usually more or less 
lobed or incised, rarely entire, 1-4 in. long, 4-2 in. wide, thinly and 
rather harshly stellate-pubescent above, more closely so beneath ; 
petioles }-} in. long, closely and coarsely stellate-pubescent ; stipules 
linear, 1 lin. long, deciduous. Racemes short-peduncled, rather dense ; 
lower female pedicels in fruit } in. long or rather longer. Male calyx 
globose in bud, closely and coarsely stellate-pubescent ; lobes ovate- 
lanceolate. Petals yellowish-white, lanceolate, shorter than the 
calyx-lobes. Stamens 5-10, 1-2-verticillate. Female sepals lanceolate. 
Petals linear, as long as the calyx-lobes. Capsule 3-coccous, pari 
purple, about 4 in. wide, loosely clothed with floccose flat scales ae 
fringed denticulate margins. Seeds rough.—Decaisne in Ann. Sci. a
