952 cxv. EUPHORBiACE^. [Euphorlia 



covered with brov/n sand, near S. Antonio, plentiful ; fl. fallen, 21 July 

 1859. No. 634. 



Nearly related to E. Bursel Boiss. in DC, I.e.. p. 167, and Icon. 

 Euphorb. p. 23, t. 110 (1866), but it differs by the petiolate stem- 

 leaves, hairy filaments, etc.

 Mant. alt. p. 564 (1771); Boiss. in DC, I.e., p. 167.

PuxGO Andoxgo. — Suffruticose, heath-like, glaucescent, woody and 

 thick at the base ; rootstock woody, perennial, giving off at the apex 

 several erect or ascending wiry rather slender puberulous or glabrate 

 stems which are about a foot high ; stems undivided and losing most 

 of their leaves from the base to about a third of their length, loosely 

 branched above, often umbellately branched at the top ; branches 

 leafy ; leaves approximated, scattered, spreading or the lower ones 

 reflected, linear, narrowly mucronate at the apex, sessile, rigid, 

 minutely pulverulent or glabrate, j to nearly ^ in. long, uninerved ; 

 the lateral margins revolute, entire ; stipules ; Inflorescence terminal, 

 sessile, tripartite ; the two lateral cymules shortly stalked, bibracteate 

 at the base, small. The central cymule subsessile, ebracteate at the 

 base, broader than the lateral ones ; bracts oblong, mucronate, not 

 connate, about ^ in. long, exceeding the lateral cymules ; involucre of 

 the central cymule campanulate-hemispherical, ^ in. long, somewhat 

 compressed, minutely pulverulent outside, shortly puberulous inside ; 

 the lobes about 7, quadrate or ovate, small, ciliate-fringed at the apex ; 

 the external glands intermediate, unequally broad, transversely oval or 

 oblong, peltately saucer-shaped, not or sometimes cornuate, about as 

 high as the lobes, glabrous on the margin ; filaments about equalling 

 the involucre ; bracteoles hairy, among the filaments and about the 

 same length ; ovary stipitate, shortly exserted, tricoccous, puberulous ; 

 styles united about half-way, the branches bifid ; capsule 4 in. long, 

 minutely puberulous-punctate ; seeds smooth. In the drier thickets 

 between Quisonde and Condo, rather rare ; fl. and f r. middle of March 

 1857. No. 286. 



I have not seen the type of this species ; the original description gives 

 the involucral lobes as four ; the determination is therefore doubtful. 



2. BUXUS Tournef., L. ; Benth. & Hook. f. Gen. PI. iii. p. 266. 



The following No. has the appearance of this genus, and is 

 possibly the variety myrtifolia of B. sempe7'vi7'e7is L. Sp. PI. edit. 1, 

 p. 983 (1753) ; being without fl. or fr. it is uncertain : — 



HuiLLA. — A shrublet nearly glabrate or minutely, puberulous 

 especially on the tetragonal branchlets and on the very short petioles, 

 1 to 3 ft. high, with the habit of a Box, glaucescent ; leaves apparently 

 evergreen, somewhat glossy, coriaceous, elliptical ovate or lanceolate, 

 wedge-shaped at the subsessile base, more or less obtuse at the apex, 

 ^ to 1 in. long by ^ to § in. broad, recurving along the margin, with 

 numerous inconspicuous veins and the midrib prominent beneath. On 

 the rocky ridges at the top of Sierra de Xella not far from Mumpulla, 

 about 4000 to 4100 ft. alt., Oct. 1859 and June 1860, abundant. No. 409. 



The wood is like that of the ordinary Box. 



The plant should be compared with B. hi'i/f/ueUe?isis Gilg in Engl. 

 Bot. Jahrb. xxviii. p. 115 (15 Dec. 1899), which belongs to Huilla, but 

 an authentic specimen of which I have not seen.
