IV. ANONACEjE 



[Anona 



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



Trees or shrubs with bisexual fl. Sepals small, petals 6 or 3. Stameus 

 indefinite, 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. Vera. Sitaphal, Saripha, Hind. 



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

 with a peculiar smell. Fl. 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. Fruit 2-4 in. diam., seeds oblong, brownish black. 



reat part of India, 



Indigenous in the West Indies, completely domesticated over a 

 cultivated as far north as Gurdaspur in the Punjab. Fl. H. S. 



Other species cultivated in India : 2. A. muricata, Linn. ; Sour-sop. 

 Linn. ; Bullock's heart. Verii. Ramphal. 



3. A. reticulata, 



Order V. MENISPERMACE^l. Gen. PI. i. 30. 



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

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

 usually 6, the outer 3 often minute. Petals usually G, sometimes wanting. 

 $ : Stamens commonly G, free, opposite to petals, or anthers on a staminal 

 column. J : Carpels distinct, 3, sometimes more, or 1 only, ovule 1 (2 in 

 Fibraurea). 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 has broad medullary rays, 

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

 have concentric bands of bast (phloem) in the wood. This is the case in Cissampelos 

 Pareira, Cyclea Burmanni, Cocculus macrocarpus, villosus and Leceba, and also in Coc- 

 culus laurifolius, one of the few trees in this order. These bands of bast 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 : Lophopltijllum bicristatum, Tlnospora cordlfblia, Cosclnium fenestratum and 

 Hcematocarpus Thomsoni.
