ZILLA (the Arabic or Egyptian name of the plant). 
Orv. Crucifere. A small genus (four species) of half- 
hardy, suffrutescent herbs, inhabiting North Africa, Arabia, 
and Persia. Flowers white or violet, solitary or loosely 
racemose, ebracteate. Leaves oblong, toothed, rather 
thick. Two of the species have been introduced, but 
probably they are not now in cultivation. 
ZINGIBER (from the Greek Zingiberis, used by 
Dioscorides, which is in its turn derived from the Sanscrit, 
and means in that language horn-shaped; probably in 
reference to the form of the rhizomes). Including Zerum- 
bet. TRIBE Zingiberem of ORD. Scitaminee. A genus 
comprising about twenty species of stove or greenhouse, 
perennial herbs, with horizontal, tuberous rhizomes, in- 
habiting the East Indies, the Malayan Archipelago, and 
the Mascarene and Pacific Islands. Flowers one to three 
to a bract, borne in spike-like, dense, cone-formed, or 
rather long thyrses; calyx tubular, shortly three-lobed ; 
corolla lobes narrow, the upper one erect, incurved, the 
lateral ones spreading; lip or lips entire or shortly bifid, 
Sometimes slightly crisped. Stems leafy, floriferous or 
sterile. Several of the species are grown in our hot- 
houses as curiosities. The rhizomes of Z. officinale furnish 
the well-known spice called ginger. The plants here 
described thrive in a compost of loam, peat, and sand, 
and require stove heat. They may be increased by 
divisions. During the winter many die down, and then, 
ar growth begins again, water should be almost with- 
eld.
