8 mm. in diameter, glabrous: seeds oblong, 4 mm. long, smooth, carun- 
culate. — Collected by C. G. Pringle on the hills of Las Sedas, Oaxaca, 
altitude 1850 m., 22 July, 1897, no. 6698. 
A species belonging apparently to the section Podnsettia and having its 
affinity with H. restiacea, Benth., from which it is distinguished by the 
larger broader leaves, the broad lobes of the involucre, and by the pres- 
ence of five glands. 
Buxus pubescens. Shrub or small tree 4.5 to 8 m. high: stems 
and branches covered with a grayish bark; the branchlets and younger 
shoots provided with a soft spreading pubescence: leaves opposite or 
occasionally subalternate, sessile or nearly so, rhombic-ovate to oblong- 
ovate, 2 to 5 cm. long, 1.5 to nearly 3 em. broad, 3-nerved, obtuse or 
acutish, mucronate, cuneate at the base, entire, ciliate, soft-pubescent 
beneath, more sparingly pubescent and glabrate above showing the reticu- 
late venation on the upper surface: inflorescence of axillary short-pedun- 
culate much contracted subracemose pubescent floral clusters: staminate 
flowers pedicellate ; pedicels 3 mm. long, about twice exceeding the 
ovate acute bracts: calyx deeply 4-parted; divisions ovate, acute, 2 mm. 
long, the inner divisions slightly broader than the outer ones: the rudi- 
mentary pistil somewhat quaterfoil or X-shaped: fertile flowers about 
5 mm. long, single, sessile, terminating the inflorescence; ovary glabrous ; 
fruit not seen, — Collected on Maria Madre Island by E. W. Nelson, 3- 
25 May, 1897, no. 4221. 
A species apparently endemic in the Tres Marias Islands, and most 
nearly related to the West Indian B. pulchella, Baill. 
etastelma macropoda. Stems twining, slender, terete, above 
48 well as the branches decussately pubescent in two lines: leaves petio- 
late, elliptic-oblong to elliptic-lanceolate, 1.5 to 2.5 em, long, 4 to 7 mm. 
toad, mucronate or simply acute at the apex, narrowed below to a 
rounded or obtusish base, glabrous on either surface, or slightly puberu- 
lent on the midrib above, margins ciliolate, usually revolute; petioles 2 
4mm. long, puberulent above, glabrous beneath: peduncles 3 to 18 
im. long, these as well as the pedicels minutely pubescent; pedicels 2. 
to 3 mm. long: flowers small: calyx-lobes ovate, obtuse, about 1 mm. 
long, Margins scarious: corolla white or cream-colored, about 4 mm. 
breadth; lobes elliptic-oblong, obtusish, rather closely pubescent 
above: column short: mature fruit not seen,— Collected by C. G. 
rele in Tomellin Cafion, altitude 1540 m., 17 July, 1897, no.
