Wallich identified this with a Japanese tree described by Ksempfer (Amoen. 

 Exot. 798) under the name of Jttbai (vulgo Jamma momu). Hooker, Bot. Mag. 

 t. 5727, is of opinion that it may be a variety of M. Nagi, Thunb. {Na, vulgo 

 N^agi, tdkkwra siba, Ksempfer Am. Exot. 773, 874), to which he refers as a syn- 

 onym M. integrifolia, Eoxb. Fl. Ind. iii. 765 ; Wight Ic. t. 764, 765, a shrub or 

 tree of Silhet, the Kasia hills, and Assam, with an ovoid drupe, the size of a 

 prune, yellow when ripe, which ripens in May, is too sour to be eaten raw, but is 

 pickled and used as a condiment. M. Nagi, Thunb., is synonymous with M. 

 ruhra, Sieb. et Zucc. ; Benth FL Hongkong. 322 ; it is a large tree, not un- 

 common on the hills in Japan (vern. Jamamo WoM), and much cultivated on 

 account of its deep-red purple acidulous fruit in Japan and China, which is 

 eaten raw and cooked. The characters by which these three species are gen- 

 erally distinguished are as follows : male catkins simple, not paniculate in M. 

 Nagi, paniculate in M. integrifolia and sapida, the partial catkins short, few- 

 flowered, closely approximate in M. integrifolia, with the bracts la^er, as long 

 as or longer than the stamens. The number of stamens varies. Dr Hooker's 

 view is probably correct, and when it is fully established, the North Indian 

 tree must then be called M. Nagi, Thunb., with a wide range, from the Panj&b 

 to Japan, and from China to the sea-coast of Singapore and Borneo, where it 

 grows as a shrub 12 ft. high. 



Myrica Gale, Linn. ; Hook. Stud. Fl. 347, Sweet Oale, or Bog Myrtle, is a 

 deciduous gregarious aromatic shrub in peat-bogs, moors, and wet places 

 of Britain, North and Central Europe, North Asia, and North America, which 

 flowers before the leaves come out in April, May, and ripens its fruit (compact 

 resinous spikes) in August. 



The following, and probably several other species of this genus yield vege- 

 table wax, which forms the outer covering of the fruit : 1. M. cerifera, L., 

 Bayherry or Wax Myrtle, a small shrub of North America, shores of Lake Erie 

 and sea-coast to Florida, with numerous small nuts encrusted with white wax. 

 2. M. cordifolia, L., the Wax Myrtle or Gandleherry bush of dry sand-hills in 

 South Africa and the Cape of Good Hope. Leaves ovate-dentate with cordate 

 base, fruit J in. diain. 3. M. arguta, Kunth., a monoicous evergreen shrub on 

 the mountains of Venezuela and New Grenada, and the Andes of Ecuador, Peru, 

 and Bolivia.

 Trees, rarely shrubs, with alternate pinnate often aromatic leaves with- 

 out stipules. Flowers monoicous, the male in lateral catkins, the female 

 solitary, clustered in erect or drooping spikes. Male 11. : Stamens 3-10, 

 inserted on lateral bracts, generally surrounded by 3-6 membranous scales j 

 anthers 2-ceUed, filaments short. Female fl. : Perianth adnate to ovary, 

 sometimes enclosed by foliaceous bracts, connate and cup-shaped at the 

 base ; ovary 1-celled with 1 erect ovule. Fruit a 1-seeded 2-valved nut, 

 often incompletely 2- or 4-celled at the base, and enclosed by a coriaceous 

 or fleshy pericarp, which remains attached to the nut or eventually separ- 

 ates from it. Seed without albumen, cotyledons fleshy, oily, sinuous or 

 corrugated, 2-lobed, radicle short, superior. 



Fruit a large woody nut, enclosed in a thick coriaceous-fleshy 



pericarp, which separates from it when ripe . . .1. Juglans. 



Fruit small, enclosed in large foliaceous bracts, in drooping 



spikes ; pericarp not separating from the nut ... 2. Engelhaedtia^
