staminodia, the anthers attached on the back, and l-lo- 

 culed: fr. a long, 4-9-angled, 1-loculed pod with 3 

 valves, the seeds immersed in the spongy contents of 

 the valves. 



oleifera. Lam. (M. pferygospirma, Gsertn.). Hoese- 

 KADisH Tree. Figs. 1420, 1421. Small tree (reaching 

 2."> ft.), with soft wood and corky bark, the young parts 

 pubescent : Ivs. mostly 3-pinnate, 1-2 ft. long, all parts 

 stalked: fls. whitish, stalked, fragrant, 1 in. across: pod 

 often l]/i ft. long, 9-ribbed, bearing 3-angled, winged 

 seeds. India, but now spontaneous in parts of the W. 

 Indies. — The Horse-radish Tree is so named from the 

 pungent taste of the root, which is sometimes eaten. 

 The young fr. is also edible. The seeds (called ben- 

 nuts ) yield an oil, whicli is more or less used in the arts.

MORHODES (Greek, a grotesque creature). Oreki- 

 (friicir. This genus is remarkable for the interesting 

 form of its flowers, which suggested the name given to 

 the genus by Lindley. The plants are rather large, 

 with long, tapering pseudobulbs sheathed by the dry 

 bases of the fallen Ivs. : Ivs. long, plaited, deciduous in 

 the autumn; raceme from the base of the pseudobulbs 

 bearing many showy fls.: sepals and petals subequal, 

 mostly narrow; labellum firmly united with the column, 

 with revolute margins, rarely concave, turned to one 

 side; column without appendages, twisted in the oppo- 

 site direction from the labellum. Distinguished from 

 the closely related genus Catasetum by its perfect fls. 

 and wingless column. 



Mormodes are commonly found in poor condition 

 among the collections, which is the result of neglect 

 rather than difliculty of cultivation. They should be 

 grown in small baskets suspended from the roof, in a 

 compost of equal parts of clean chopped peat-fiber, sphag- 

 num and sod, interspersed by nodules of charcoal, and 

 the whole pressed in firmly around the roots. The roots 

 like to work among the charcoal, and this also serves 

 the purpose of dividing the compost, thereby allow- 

 ing it to dry out more readily. Mormodes do not require 

 an abundance of water at any time, and the compost 

 should frequently be allowed to dry out during the 

 growing season. When at rest, an occasional ap- 

 plication will suffice to keep the soil moist and 

 the pseudobulbs from shriveling. Rebasketing 

 should take place at the commencement of new 

 growth in spring. They ail require warmbouse 

 temperature; the Cattleya or Cypripedium depart- 

 ment affords them a proper location regarding 

 temperature and moisture.
