The first representative of the genus recorded from the Philippines, only one 
specimen with a single flower seen. It belongs to the section Hesantha, and is 
allied to G. longipes King & Plain. 
Species of this genus are comparatively seldom met with in flower in forests 
owing to the fugacity of their flowers, and these plants are seldom obtained by 
collectors of herbarium specimens. There are probably more species in the 
Philippines, but the only way to obtain satisfactory material is to bring in the 
living plants and cultivate them. 
5. CURCUMA L inn. 
Herbs with aromatic rhizomes and tuberous or fibrous roots. Leaves 
oblong or obovate, usually tufted, rarely solitary. Spikes peduncled, 
from the rhizome, with the leaves or not. Bracts persistent, forming a 
cone, usually brightly colored, the uppermost ones often empty, longer 
and of a different color. Flowers several in each bract, with several 
bracteoles, short-lived. Calyx short, cylindric, toothed. Corolla-tube 
broad, funnel-shaped, the lobes ovate or oblong. Stamen oblong, peta- 
loid. Lip orbicular or obovate. Filament of stamen short, broad. 
Anther-cells parallel, sometimes spurred at the base, crested or not. 
Style filiform. Ovary 3-celled, many-ovuled. Capsule membranous, 
globose, 3-valved. Seeds arillate, ovoid or oblong. 
Species about 35, India to Siam, Malaya, and Australia. 
The greater part of the genus is Indian and Burmese, and of these species 
several have been widely distributed in the East in cultivation, and have there 
occasionally established themselves in and near villages, or persisted long after 
the villages have disappeared. Such are the species occurring in the Philippines.
