4. CELTIS L. Enoki Zoku 



Usually deciduous trees; leaves alternate, entire or toothed, often oblique at base, penninerved, with 3 main nerves from the 

 base, the stipules free, lateral; inflorescence cymose, staminate or polygamous, axillary or from the base of young branchlets, 

 the flowers 5(or 4)-merous, the bisexual 1-3, axillary, pedicelled; perianth-segments and stamens usually 5; ovary sessile; style bifid, 

 the lobes subplumose and often twice bilobed; ovule pendulous, anatropous; drupe juicy, ovoid to globose, the endocarp bony, often 



rugose or reticulate; seeds with scanty endosperm, the embryo curved. About 70 species, in temperate to tropical regions of 



the N. Hemisphere.

5. APHANANTHE Planch. Muku-no-ki Zoku 



Deciduous trees; leaves petiolate, alternate, toothed, with the largest lateral nerves from the base, the stipules free and lateral; 

 staminate inflorescence cymose, axillary near base of young branchlets, rather many-flowered; flowers 4- or 5-merous; pistillate

Fam. 68. MORACEAE Kuwa Ka Mulberry Family 



Evergreen or deciduous, dioecious or monoecious trees, shrubs or rarely herbs, often with colored juice; leaves alternate, entire 

 or toothed, sometimes lobed, the stipules prominent, deciduous; inflorescence basically cymose; flowers small, actinomorphic, 

 spicate, capitate, or on the inner side of a fleshy urceolate receptacle (syconium oi Picas); staminate flowers 2- to 4(-6)-merous, 

 the stamens opposite the segments, the filaments erect or incurved in bud; pistillate perianth 4-lobed or -parted; stigmas 1-2; 

 ovary superior or inferior, widi a solitary pendulous ovule; fruit a small achene or drupe, the perianth and axis sometimes ag- 

 gregated or connate, forming a syncarp, the embryo curved. About 55 genera, with more than 1,000 species, chiefly in the 



Tropics, few in the temperate regions of the world.
