22 IV. ANONAOE-E [Anona 



15. ANONA, Linn. ; M. Brit. Ind. i. 78. 



Trees or slirubs with bisexaal fl. Sepals small, petals 6 or 3. Stamens 

 inclefinitej crowded round a hemispherical torus, connective overlapping the 

 anthers. Carpels united into a large fleshy fruit, seeds numerous, embedded 

 in a soft pulp. 



A. squamosa, Linn. Custard apple, Vern. SitajjJial, Saripha, Hind. 



Wholly glabrous, leaves oblong-lanceolate, 2-3 in. long, pellucid dotted, 

 with a peculiar smell. M. greenish, single or in pairs, on pedicels as long as 

 flower. Exterior petals lanceolate, triquetrous, thick and fleshy, 1 in. long, 

 3 interior minute or wanting. Truit 2-4 in. diam., seeds oblong, brownish black. 



Incligeaious in the West Indies, completely domesticated over a great part of India, 

 cultivated as far north as Giirdaspnr in the Punjab. El. H. S. 



Other species cultivated in India : 2. A. muricata, Linn. ; Soursop. 3. A, reticulata, 

 Linn. ; Biillocli^s heart. Vern. Ramphal. 



OifflEBV. MENISPERMACE^. Gen. PL i. 30. 



Climbing or twining, rarely erect shrubs. Leaves alternate, usually palmi- 

 nerved, often peltate, stipules 0. PL small, dioecious or polygamous. Sepals 

 usually (), the outer 3 often minute. Petals usually 0, s'>me times wanting. 

 cj : Stamens commonly (J, free, opposite to petals, or anthers on a staminal 

 oilumn. ? : Carpels distinct, 3, simetimes more, or 1 only, ovule 1 (2 in 

 Flbrattrea), Fruit generally drupaceous, the seed enclosed in a woody or 

 coriaceous endocarp, usually curved or horseshoe shaped, scar of style often 

 near the base of carpel. 



Remarkable anatomical characters. — The wood of all species lias broad medullary rays, 

 alternating with broad wedges of wood, and as a rule very large vessels. Many sj^ecies 

 have concentric bands of bast (pliloc^m) in the wood. This is the case in Cissampelos 

 Pareira, Cydea Burmanni^ Cocculus macrocarpus, mlloms and Lemha, and albo in Coc- 

 culus latirifolni9j one of the few trees in this order. These bands of babt in the wood 

 have been called concentric, frequently however they are partial, alternating masses 

 of wood and bast occupying portions only of the circumference. 



The following species, and probably many others besides, have no bands of bast in 

 the wood: Lopfiophylhtni hicribtatum, Tinospora cordifolla^ Coscinium fenestj^atmu and 

 Hmmatocarpus Thom^onL
