1 66 RIDLEY. 



Stamen-filament thick, fleshy. Anther oblong, crest small, sometimes 

 absent. 



Species about 30, Indo-Malayan or Siamese.

Khizome not seen. Leaves two, elongate, linear-lanceolate, obtuse, 

 thin, glabrous on the upper surface, beneath sparingly pubescent, 14 cm 

 long, 2 cm wide, the keel elevated at the rounded base ; petiole 5 to 9 cm 

 long. Spike central, 4 cm long, subcylindric. Bracts lanceolate, acumi- 

 nate, pubescent especially on the edges. Calyx spathaceous, short. 

 Corolla-tube slender, 4 cm long, the lobes lanceolate, acute, 8 mm long. 

 Lip a little longer, obovate, the margins crisped. Stamen half as long; 

 anther linear, the crest long, oblong, apex rounded, ovate. 



Mindanao, District of Zamboanga, Port Banga, For. Bur. 9110 Whitford & 

 Hutchinson. 



The first representative of the genus recorded from the Philippines, only one 

 specimen with a single flower seen. It belongs to the section Mesantha, and is 

 allied to G. lonyipes King & Prain. 



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 Linn. 



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.
