162 KEY TO SUB-CLASSES, ORDERS AND GENERA. 
LXX—EBENACEA— 
[Anatomical featwres.—Like SaPpoTacEs, the Ebonies have concentric bonds of 
wood parenchyma, appearing like transverse bars across the medullary rays ; but 
they are often extremely fine and difficult to see. The wood fibres have minute 
bordered pits. The wood of many species is dark grey, and in the stems of some 
species, when old, irregular masses of jet-black wood are formed, sometimes 
alternating with strata of lighter coloured wood, In this jet-black wood (Ebony) 
the vessels and wood-fibres are filled with a black substance, the nature and origin 
of which are not known. ] 
(I) Flowers mostly 3-merous, ovary 3-or 6-celled:  ... nee .» dlxi— Maba. 
(II) Flowers mostly 4—5-merous ; ovary 4-—5-, or 8--10-celled :— 
dlxii—Diospyros. 
LXXI--STYRACEAi— 
[Anatomical featwres.—Stellate hairs and flat round peltate scales are frequent. 
The wood-fibres have bordered pits. | 
(1) Stamens numerous in several series ; ovary inferior, 3-celled :— 
dlxiii—Symplocos. 
(II) Stamens 10, in one series; ovary free, dissepiments reaching only to 
the middle :— cide Abc soc wh oe dae 500 --. Glxiv—Styrax. 
LXXII—OLEACEA— 
{ Anatomical featwres.—The climbing species of Jasminum have, as far as 
known, wood cf a normal structure ; but the stems are often spirally twisted, and 
in some cases wedges of bast intrade into the wood. | 
(1) Leaves or leaflets penninerved (rarely-Jasminuwm—s%.costate) ; mostly 
trees and shrubs, or (Jasminum) climbers :——

(ii) Fruit a bipartite, orbicular, compressed capsule, separating when 
ripe into two sub-discoid carpels; leaves simple; corolla salver-shaped, wiite

(iii) Fruit a woody capsule, dehiscing loculicidally with septiferous 
valves; albumen O; leaves imparipinnate; corolla salver-shaped, white with

(3) Corolla funnel-shaped ; inflorescence of terminal racemes or panicles ; 
shrubs :— au ade 406 ae 00 ue dlxxii— Ligustrum. 
(4) Corolla thick globular 4-cleft, yellowish ; flowers in axillary clusters ; 
trees :— wit eae Se ae ves ee dlxxiii— Noronhia. 
(II) Leaves prominently 3-costate ; large climber with 4-angular branches ; 
fruit globose, 1-seeded, with crustaceous pericarp; flowers small, yellowish, in 
axillary and terminal trichotomous panicles :— de Ae dixxiv—Myxopyrum. 
LXXITI—SALVADORACH Al— 
{Botanical note-—In HK. 3-619, C. B, Clarke supposes Roxburgh’s Blackburnia 
monadelpha to be the same as his Dobera Roxburghit; the following is Roxburgh’s 
description, and the two hardly seem to tally :—- ‘‘ Calyx 4-toothed ; corol 4-petalled ; 
nectary a staminiferous ring surrounded by the base of the germ ; Berry superior 
1-seeded ; seed arilled ; arboreous ; leaves alternate, lanceolate ; filaments united at base. 
A large erect timber tree, a native ot the mountainous parts of the Circars; flowering 
time, the beginning of the hot season. Trunk erect ; bark thin, firm, yellowish-green 
on the outside, in the inside deep red, tinging the spittle with that colour ; it is a strong 
astringent ; branches numerous, forming a large shady head, leaves alternate, short 
petioled, linear-oblong, smooth, below a little whitish, entire, waved, pointed, five or six
