1. M. Duseniiy Hutchinson. A tree or shrub ; branchlets piloscv 

 often more or less quadrangular when young. Leaves elliptic or oblong- 

 elliptic, caudate-acuminate at the apex, slightly rounded at the base, 

 3J-9 in. long, Ij-^ in. broad, with a remotely setulose-denticulate 

 margin, somewhat rigidly membranous, glabrous on both sides except 

 the pilose midrib and lateral nerves below ; lateral nerves 6-8 on each 

 side, looped aiid branched near the margin, slightly prominent on the 

 lower surface ; tertiary nerves subparallel or branched, distinct below • 

 petiole |-3^ in. long, rather slender, setulose ; stipules foliaceous, broadly 

 falcate, 7 lin. long, 4 lin. broad, glabrous on one side, setulose and with a 

 strong nerve near the concave margin on the other side. Male racemes 

 produced in dense clusters on the old wood (trunk?), about 2 J in. long; 

 axis deeply grooved, minutely puberulous ; bracts very minute. Male 

 flowers seen only in very young bud, glabrous. Female racemes prc)- 

 duced on the old wood, about G in. long; axis sulcate, minutely and 

 sparingly puberulous ; bracts minute, pubescent ; pedicels \ lin. long, at 

 length reflexed, glabrous. Calyx 5-lobed ; lobes truncate or rounded 

 at the apex, glabrous. Disk cupular, enclosing about J of the ovary, 

 ciliate. Ovary 3-celled, ovoid, glabrous; stigmas 3, rounded, sessile, 

 minutely bifid. Fruits (immature) obovoid, contracted and some- 

 what acute at the base, 5 lin. long, 3 lin. in diam., purplish-red when 

 dry, glabrous. — Slaphyscra Dusenii, Pax in Engl. Jahrb. xxiii. 521.

 93. A shrub ; young branchlets very sparingly puberulous. Leaves 

 oblong-elliptic or obovate-lanceolate, rather abruptly acuminate, sub- 

 cuneate at the base, 4-cvJ in. long, 1J-2J in. broad, margin remotely 

 but distinctly denticulate, rather rigidly membranous, glabrous on both 

 surfaces ; lateral nerves 6-8 on each side, looped and branched towards 

 the margin, prominent on the lower surface ; tertiary nerves few and 

 distant, branched ; veins and veinlets scarcely visible ; petiole J-1 in. 

 long, sparingly setulose when young, at length glabrous ; stipules con- 

 spicuous, at length deciduous, f.alcate, the concave margin encircling the
