7Cupho7'hla.] cxxir. euphorbiace.€ (brown). 595 



witli a small solid central part, glabrous; angles wing-like, scarcely 

 toothed. Spines J in. long, in pairs about | in. apart, diverging, dark 

 brown. Flowering-eyes about J in. above the spine-pairs. Cymes 3-6 

 from each flowerini;-eye, with peduncles 3-5 lin. long, each with 1 sessile 

 involucre or 1 se^^sile and 1 or 2 shortly pedunculate involucres, glabrous. 

 Bracts thin, submembranous, ad pressed to the involucres, J in. long, 

 J in. broad, broadly rounded. Involucres about 4 lin. in diam. and 

 2-2| lin. deep, cup-shaped, glabrous, with 5 glands and 5 transversely 

 oblong fi-inged lobes; glands not contiguous, lJ-2 lin. in their greater 

 diain., transverse, reniform or somewhat half-circular, slightly 2-lipped, 

 entire, more or less undulate when dried. Ovary sessile, included in 

 the involucre, compressed, 2-celled, fleshy, glabrous, with a calyx divided 

 into several linear or linear-filiform segments as long as the ovary; 

 styles 2, about 1-| lin. long, moderately stout, shortly united at the base, 

 then recurved-spreading, entire at the apex.

Closely rehited to JS?. cah/cina, N. E. Br., and Imving the same kind of conspicuoiis 

 calyx, but the iiivi)hu-re is larji^er, the ovary is sessile, includeil in the involucre, 

 and appears to be constantly 2-celled, and the 2 styles are longer and stouter than in 

 E. caLycina. 



181. E. acrurensis, N'. E. Br. Arborescent, succulent, spiny. 

 Branches of the dried specimens seen 7-angled and about -4 J in. in diam., 

 with the solid central part about 1-1 J in. thick and much less in diam. 

 than the angles are broad (seedling plant 3-angled and 1-1| in. in 

 diam.); angles wing-like, 2 in. broad and 2 lin. thick at the edge in the 

 dried specimen, with triangular channels 1| in. deep between them. 

 Leaves not seen. Spines 1^-5 lin. long, in pairs, diverging, stout at 

 the base, blackish-grey on the seedling, becoming grey with darker tips 

 with age, on suborbicular horny shields 3-4 lin. in diam. on the mature 

 branch, much smaller on the seedling, not connected b}' a horny border 

 along the angles, becoming grey with age, with the flowering-eye touching 

 or subincluded in their apical part. Cymes (detached, but distributed 

 with the stem-sections) on peduncles \-\ in. long, bearing 3 involucres, 

 the middle one sessile and the two lateral on cyme-branches 1 lin. long, 

 glabrous. Bracts thin, adpressed, broken, but apparently suborbicular 

 and about 3 lin. long and 2^-3J lin. broad, very concave. Involucres 

 J-J in. in diam., cup-shaped, golden-yellow (Sch^veinfurth), with 0-8 

 glands and 5-8 trans ver.-ely rectangular fringed lobes, glabrous ; glands 

 1^2 lin. in their greater diam., erect in dried flowers, transverse, reni- 

 form, with the middle of the inner margin turned in and forming a 

 small lip, or crescent-shaped, with the inner margin concave, in dried 

 specimens with th6 outer margin more or less incurverl. Ovary sub- 

 sessile and included when young, in fruit exserted and curved to one 

 side on a short stout pedicel, glabrous ; perianth fleshy, with 3 lobes 

 2-2J lin. long, deeply cut into 2 or more filiform segments or entire 

 and subulate-acuminate, in fruit reflexed and the segments often broken 

 off; styles l|-2 lin. long, shortly united at the base, rather stOut, 

 slightly thickened and minutely 2-lobed at the apex. Capsule 5-G lin.
