Yams {Dioscorea spp. )• — Several varieties are cultivated by the natives; one 

 species jjrows wild. They are planted in April, tlie soil having l^een previously 

 dug deeply. The crop will Ije ready about December. The maturity of the 

 tubers is indicated by the turning yellow of the leaves. Yams are left in the 

 ground, to be dug as required for use. They will not keep like sweet potatoes, 

 and are therefore not suitable for taking on long voyages. For methods of 

 propagation see under Dioacorea (data.

Local names. — Mana (Guam); Asaua (Samoa). 

 A fern growing on the sabanas, or upland, grassy regions. In some islands of 

 Malanesia the wiry stipes are split and braided into baskets and into armbin('a or 

 other ornaments. In places where the sabanas have been burned over the stiff, erect 

 stipes project a few inches above the surface, and often cause wounds in the feet of 

 the natives, even when the latter are protected by leather sandals.

 petioled leaves arranged in two rows, closely veined beneath and shortly pointed at 

 each end. Flowers small in axillary clusters, shortly {)edicelled, aj)etalous, without 

 disk scales or glands; calyx of both sexes of 2 large and 3 minute sepals, that of the 

 female flower larger than that of the male; male flower without pistillode; anthers 

 3, growing together in an ol)long sessile column; female flower with 5-celled, globose, 

 smooth ovary; styles growing together in an elongated, subcylindrical column, grad- 

 ually narrowing from the base to the apex, 3 or 4 times as long as the ovary, the 

 apex shortly 5-toothed; capsule depressed globular, finally 5-lobed. This species

The type specimen of this species is from the island of Guam, where it was col-
