10. M. Barter!, Hutchinson. A hlirub or small tree 8-25 ft. 

 high, with haid wood (Millen) ; young branchlets yellowish-brown 

 pubescent, almost glabrous when older. Leaves elliptic, oblong-elliptic 

 or obovate, acutely cuspidate-acuminate, rounded at the base, 2J-9 in. 

 long, lj-4J in. broad, membranous or papery, margin repand-denticulate 

 or dentate, glabrous above (except on the midrib), sparingly and shortly 

 pubescent below, midrib setulose ; lateral nerves (l-i) on each side, looped 

 and reticulate near the margin, slightly impressed above, prominent 

 and setulose below; tertiary nerves usually inconspicuous above, sub- 

 parallel; veins lax; petiole |-'2J in. long, somewhat slender, terete, 

 more or less densely brown-pubescent; stipules subulate, entire, nearly 

 2 lin. long, pubescent. ]\[ale racemes in clusters, usually arising from 

 the older wood of the branchlets or branches, l-2h in. long; axis 

 tomentellous ; bracts conspicuous, ovate, acute, pubescent ; pedicels 

 short. Flower when expanded scarcely over 1 lin. in diam. Calyx 

 4-5-partite ; lobes oblong-ovate, obtuse, sparingly pubescent. Disk- 

 glands large, fleshy, sparingly pilose. Stamens -i-b ; filaments glabrous. 

 Rudimentary ovary colutunar, long-pilose. Female racemes arising in 

 dense clusters from the old wood, about 2 in. long at the time of 

 flowering ; axis tomentose. Flowers solitary or subsolitary in the axil of 

 each bract; bracts trianuular, acute, sparingly pubescent. Cal3'x 5-H- 

 partite ; lobes ovate, obtuse, glabrous or nearly so. Disk shortly 

 cupular, ciliolate. Ovarv ovoid, densely pilose ; styles bipartite, seg- 

 ments very short. Fruiting raceme^i up to -1 in, long ; pedicels about 

 1 lin. long. Fruits ellip-oid, tipped by the short persistent styles, 

 about 4 lin. long and 2^ lin. in diam., puberulous. Seeds about '< lin. 

 long; testa bright red and membranous. — Pierardia Barteri, Baill.

Schmidelia? rejlexa. Baker in Oliv. Fl. Trop. Afr. i. 425, described from a 

 specimen collected by Mann (1742) at Corisco Bay, is evidently a McBsohoirya, 

 and may be a large-leaved form of this species. 



11. M. griffoniana, Pierre MSS. A large shrub or tree 0-20 ft. 

 high ; branches subterete with greyish bark ; branchlets terete, glabrous. 

 Leaves oblong-elliptic or slightly obovate-elliptic, caudate-acuminate, 

 very slightly rounded or subcuneate at the base, 3-6 in. long, 1 J-3 in. 

 broad, rigidly membranous or somewhat papery, margin distinctly 

 recurved, entire, glabrous and very slightly shining on both surfaces ; 

 lateral nerves 6-8 on each side, proaiinent on the lower surface, distinct! v
