10. M. Barteri, //utchinson. A shrub or small tree 8-25 ft. 
high, with hard wood (Millen); young branchlets yellowish-brown 
pubescent, almost glabrous when older. Leaves elliptic, oblong-elliptic 
or obovate, acutely cuspidate-acuminate, rounded at the base, 24-9 in. 
long, 14-4} 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 6-9 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 3-24 in. long, somewhat slender, terete, 
more or less densely brown-pubescent ; stipules subulate, entire, nearly 
2 lin. long, pubescent. Male racemes in clusters, usually arising from 
the older wood of the branchlets or branches, 1-24 in. long; axis 
tomentellous ; bracts conspicuous, ovate, acute, pubescent; pedicels 
short. Flower when expanded scarcely over 1 lm. in diam. Calyx 
4—5-partite ; lobes oblong-ovate, obtuse, sparingly pubescent. Disk- 
glands large, fleshy, sparingly pilose. Stamens 4-5; filaments glabrous. 
Rudimentary ovary colu mnar, 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 triangular, acute, sparingly pubescent. Calyx 5-6- 
partite; lobes ovate, obtuse, glabrous or nearly so. Disk shortly 
cupular, ciliolate. Ovarv ovoid, densely pilose; styles bipartite, seg- 
ments very short. Fruiting racemes up to 4 in. long; pedicels about 
1 lin. long. Fruits ellipsoid, tipped by the short persistent styles, 
about 4 lin, long and 23 lin. in diam., puberulous. Seeds about % lin. 
long; testa bright red and membranous.—Pierardia Barteri, Baill.

Schmidelia ? reflexa, Baker in Oliv. Fl. Trop. Afr. i. 425, described from a 
Specimen collected by Mann (1742) at Corisco Bay, is evidently a Mesobotrya, 
and may be a large-leaved form of this species. 
il. M. griffoniana, Pierre MSS. A large shrub or tree 9-20 ft.

ves oblong-elliptic or slightly obovate-elliptic, caudate-acuminate, 
very slightly rounded or subcuneate at the base, 3-6 in. long, 14-3 in.

recurved, entire, glabrous and very slightly shining on both surfaces ; 
lateral nerves 6-8 on each side, prominent on the lower surface, distinctly
