Order CXXXIV. SCITAMINEA. (By J. G. Baker.) 
Flowers usually hermaphrodite, rarely unisexual by abortion.

Sepals equal, free or united in a tube at the base. Corolla tubular

dreecium very irregular, normally in two rows of 3 lobes each; 
stamen usually single, linear, with a 2-celled or 1-celled anther. Ovary 
inferior, usually 3-celled; style long, often involute at the apex; 
stigma terminal; stylodia often present. Fruit crowned by the per- 
sistent calyx, usually 3-celled, capsular or indehiscent. Seeds 1 or 
many in a cell, albuminous ; albumen hard or farinaceous; embryo 
central, straight or horseshoe-shaped.—Herbs, rarely shrubs, usually 
perennials ; rootstock often horizontal, dry or tuberous. Leaves oblong 
or lanceolate, cauline or all radical. Inflorescence spicate, racemose or 
panicled, produced from the end or side of the leafy stem or direct from 
the rootstock. Petaloid staminodia often showy and brightly coloured. 
Species 500, spread through the Tropical regions of both hemispheres. 
Of the common officinal species of the order, Maranta arundinacea, Curcuma 
longa, and Zingiber officinale are widely cultivated throughout Tropical Africa. The 
specimen in the herbarinm of the British Museum of Zingiber dubium, Afzel., col- 
lected by Dr. Daniell, and cited as authentic by Horaninow, is not in flower, but, as 
far as it goes, agrees with Z. officinale.
