KEY TO SUB-OLASSHS, ORDERS AND GENERA. 16] 
LXVII--PLU MBAGINACEA)— 
(I) Styles 5, distinct ; stigmas subcapitate ; stamens very shortly united at 
their base into a tube with the corolla ; small shrubs with obovate leaves :— 
dxlivy—Statice, 
(II) Style 1 filiform divided into 5 stigmatose branches ; stamens tree ; 
calyx glandular ; flowers spicate:--__... i a, is w. dxly—Plambago. 
LXVIII—MY RSINACEA)— 
[Anatomical features.—Resin cavities and resin duets are found in the leaves 
(whence leaves pellucid-punctate), pith, wood, and bark; probably some species have 
resin cavities or special cells filled with resin in the medullary rays analogous to the 
Wood Oil in the rays of Dipterocarpus alatus. | 
(I) Ovary inferior or } superior; berry many seeded, nearly enclosed by the 
calyx :— 
(II) Ovary inferior ; calyx free :— 
(i) Stamens without alternating scales (staminodes) ; fruit 1-seeded :— 
(1) Filaments none, or shorter than the anthers; fruit a globose dry or 
fleshy berry ; inland species :— 
(A) Flowers in dense axillary clusters ; corolla segments imbricate or 
valvate in bud :— i Loe Spr ... dxlviii—Myrsine, 
(B) Flowers in racemes, often panicled; corolla segments imbricate 
or contorted in bud :— ... ot es oe ... dxlix—Embelia, 
(C) Flowers usually umbellate ; corolla segments twisted, the right 
hand edge overlapping ; anthers free ; calyx glabrous:— dl—Ardisia, 
(D) Flowers in sessile umbels ; corolla segments twisted, the left 
hand edge overlapping; anthers tree, calyx persistent, hairy :— 
dli—Antistrophe. 
(2) Filaments long, exserted ; fruit cylindric, curved, dry; shrub of the 
mangrove swamps :— a3 ne sis sa : dlii— Aigiceras. 
(ii) Stamens alternating with 5 scales (staminodes); fruit yellow 1-3- 
seeded, seeds imbedded in a mucilaginous placenta; flowers vermilion in termi- 
nal racemes or umbels :— 52: oth ‘a “he Re »e  dlili— Jacquinia. 
LXIX—SAPOTACEA— 
{Anatomical features.—Shoots and young leaves of most genera are clothed with 
fine, often minute, unicellular hairs, which as a rule, are attached in the middle and 
are hence two-armed. Another feature is that of strings of cells filled with milky 
substance, which in some species yield the “ gutta-percha’? of commerce, accompany- 
ing the vascular bundles in the bark and leaves. The wood is recognized by numerous 
narrow, often fine, more or less concentric bands of wood parenchyma, and frequently 
by radial irregular belts of parenchyma surrounding the vessels. The heart-wood is 
generally red. | 
[Botanical note.—Dichopsis is called by Brandis and Bourdillon Palaquium 
(Blanco). | i
