contact around the ovary, restricting lateral access to the intrastaminal disc (tending 

 to tube-protection of secretion). 



Citrus medica, a hill-shrub, cultivated in vars. as Citron, Lemon, Limes; 

 stamens 25-55, in single palisade of strap-shaped groups; carpels 9-1 1 ; flowering 

 and fruiting throughout the year. 



C. Aiirantium, Orange, of E. Himalya, cult, in vars., stamens 15-30, carpels 

 10-13, often a reduced second whorl : moth-pollinated. 



C. (hrumana, Grape-fruit, Shaddock; flowers larger, petals recurved ; stamens 

 about ^o, in tubular palisade, 10 mm.; carpels 8-16: fruit to 8 in. diam. and 

 5-6 lb. 



Aegle Marmelos, Bael-tree, a small tree of dry deciduous forest, 40 ft., with 

 spinous branches, much cult. Flowers greenish-white, i in. diam., fragrant. Stamens 

 indef., carpels 10; Fruit an Orange-type, 4-5 in. diam., with yellow hard woody 

 rind, and numerous seeds in orange-coloured sweet aromatic pulp : taken by animals, 

 monkeys, ileer, &c. 



IV. Simarubaceae (27/125) based on ShiLiniba a medicin,il plant of 

 W. Indies, for Discifloral forms in which the carpels are united in the style-shaft, 

 but break away in the fruit-stage, and so appear ' apocarpous '. No oil-ducts or 

 glands ; the flowers more or less reduced and diclinous. 



Ailanthus excelsa, a large tree of deciduous forest, also cult., leaves pinnate 

 {12 pairs), 1-3 ft. Staminate flower with 10 stamens only: carpellary flower of 

 5 carpels, maturing fruit as 1-5 flat red samaras, 2^ in. ; seed centred and a slight 

 spiral twist at the ends. 



Cf. A. glandiilosa, China, cult., dioecious; samaras 2 in., red when mature; 

 leaflets with glandular teeth near the base : spreading by root-suckers. 



V. Burseraceae (16/320), based on American forms of Eurscra for a group 

 ■of tropical trees with resin-ducis : flowers small and of considerable range : cf. 

 Bahamodt'ndroit Rlyirha of Arabia, &c. 



Boswellia serrata, Salai, a fairly large deciduous tree, common and gregarious 

 on dry hills, leafless in hot season: Flowers small, 5 mm., green, on the bare 

 branches: stamens 5-1-5, disc intrastaniinal : ovary 3-locular, fruit dehiscing by 

 3-valved sarcocarp, with 3 pyrenae. 



Garuga pinnata, a large deciduous tree, associated with Sal and Teak; 

 flowers comparatively large, in yellowish panicles, with marked perigynous cup : 

 stamens 5 -I- 5, ovary 4-6 locular, each 2 ovules: Fruit a drupe with 2-4 tubercled 

 pyrenae persisting in soil 1-2 years. 



VI. Meliaceae (40,600), a great order of tropical forest-trees, with panicled 

 inflorescences of small Discifloral flowers, normally distinguished by the characteristic 

 utilization of a slaminal tube, as practically a gamophyllous mechanism protecting 

 the gvnoecium and ultimately also controlling the nectary : petals tend to become 

 superfluous. Fruits characteristically capsular, with winged seeds, but commonly 

 ;anging to drupes with reduced output of seeds: in one important genus at least 

 there is no staniinal tube. 



Swietenia Mahagoni, Spanish Mahogany, a great tree of Trop. Amer., leaves 

 pinnate, panicles of small flowers, 7 mm. ; staminal tube, 3 mm., urceolate, with 

 10 teeth alternating with the anthers. Fruit a woody capsule, 3 in., 5-valved, with 

 numerous winged seeds. Cf larger fruit of 6". macrophylla, 5-6 in., falling to pieces, 

 seeds winged, 3 in. 



Walsura villosa, Gyobo, common evergreen tree of Burma : flowers, small, 

 5 mm., with filaments gamophyllous below, broad and convergent above, seed with 

 fleshy aril in a pointed berry. W. robtista, similar, filaments free. 



Azadirachta indiea, Neem, cult, everywhere, monotypic ; leaves pinnate, 

 evergreen; flowers in large panicles, small, white, 10 mm. diam.; staminal tube, 

 5 mm., narrow, with 10 teeth superposed to 10 anthers: disc inside the tube; 

 carpels 3, each 2 ovules; Fruit a drupe, f in., i -seeded.
