CALYCIFLOR2E. Group II. Section 3. 
Calyx-tube adnate to the base of the ovary, or free. Ovary 1 -celled ; stamens isomerous and opposite the petals, or more numerous. 
FAMILY XXXV.-SAMYDACEiE. 
Trees or shrubs with alternate distichous simple leaves, dotted with spots or pellucid glands, racemose or crowded inflorescence and hermaphrodite flowers having the 
characters described for the Section. A mixed group, of which only 2 ligneous species are known to occur in the Province. 
140. CASE ARE A. Trees with alternate distichous simple dotted leaves. Calyx 4-5 merous ; petals none. Stamens 10 fertile and 10 alternate staminodes ; filaments united 
below into a tube. Ovary free, i-celled; style simple; ovules numerous. Stipules minute. Flowers tufted, small. 
C. gladiiformis, Mast. A tree found at Shupanga, Zambesi, by Sir John Kirk, having lanceolate leaves 12-15 c.m. long, 5 c.m. wide, oblique at the base and with a 2 c.m. 
petiole. Flowers in sessile lateral clusters. Filaments united half-way ; fertile filaments glabrous ; staminodes downy. 
141. BIVINIA. A shrub with alternate distichous stipulate stalked entire leaves, axillary racemose inflorescence; sepals 5-6 ; petals absent, stamens numerous, in bundles 
alternating with the sepals ; disc produced to 5 lobes opposite the sepals. Ovary free, 3-lobed, i-celled ; ovules numerous on 4-6 parietal placentas. Styles 4-6. 
Capsule 4-6 valved ; seeds hairy, albuminous. 
B. Jauberti, Tulasne. Shrub. Young branches downy; leaves ovate or ovate-lanceolate, 7-10 c.m. long, 3 c.m. wide, crenate-dentate, petiolate. Racemes axillary, 
erect ; flowers numerous. Ovary globose, downy ; capsule 3-lobed, downy, dehiscent, valves terminated by 2 awns from the splitting of the styles. Rovuma River. 
CALYCIFLORiE. Group II. Section 4. 
Ovary inferior. Ovules solitary in each cell. Seeds albuminous. Styles free. Stamens isomerous and alternate with the petals. 
FAMILY XXXVI.— UMBELLIFER2E. 
Flowers 5 merous, regular or the outer petals larger; stamens 5 ; ovary 2-celled, inferior; styles 2 ; ovules solitary, pendulous; carpels dry, 2-seeded, separating into 2 
indehiscent i-seeded carpels, which remain attached to the top of the halves of a split central axis. Albumen fleshy, abundant. Leaves alternate, sheathing at the base of the 
petiole. Inflorescence in regular umbels. Stems usually hollow. Petals inrolled during aestivation, often emarginate, usually white. A large group of mostly herbaceous 
plants, of which only 1 local species assumes tree form. 
142. HETEROMORPHA. Umbels compound ; calyx-limb represented by 5 teeth. Petals 5, entire, inserted near the top of the ovary. Stamens 5, alternate to the petals. 
Fruit smooth, the 2 mericarps unequal, 1 having 3-winged ridges and the other only the 2 side ridges winged. The genus contains only 1 variable species. 
H. arborescens, Ch. & Sch. Vent, names— 6, Nutchaka; 10, Mororonge ; 13, Umbangandhlala. An exceedingly variable plant; often a small shrub or almost an 
herbaceous plant with simple ovate or oblong entire blunt leaves ; other plants have lanceolate acute leaves ; others 3-foliate leaves with obovate-crenate leaflets, 
and in others the leaves are many-foliate, and the plant quite tree-like. The timber is however always soft and useless. All the varieties mentioned occur in the 
Province as also in Cape Colony and Natal, and the species occurs also in the Upper Nile and Abyssinia. 
FAMILY XXXVII.— ARALIACE2E. 
Floral characters almost as in Umbelliferae, but flowers constantly regular, petals valvate in aestivation, fruit more or less fleshy, and the stipulate leaves digitately 5-7-9 
foliate, while the inflorescence is often not umbellate. 
143. CUSSONIA. Rather small trees having soft-wooded somewhat succulent stems of large diameter for their height, spicate racemose or umbellate inflorescence, small 
green regular 5-merous hermaphrodite or polygamous flowers, inferior 2-celled ovaries with pendulous single ovules, 2 styles, and somewhat fleshy 2-cel e ruits. 
Leaves digitate or repeatedly so, usually crowded at the points of the branches. The habit of Cussonia is very distinctive among African trees and it is often 
mistaken for a Palm though very different.
