DESCRIPTIVE CATALOGUE. 283 



Yams (Dioscorea spp.). Several varieties are cultivated by the natives; one 

 species grows wild. They are planted in April, the soil having been previously 

 dug deeply. The crop will be 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 undei; Dioscorea alata.

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 armb.mc's 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.

A smooth evergreen shrubby plant with alternate, oblong-elliptic, entire, shortly 

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

 each end. Flowers small in axillary clusters, shortly pedicelled, apetalous, 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 oblong 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 

 has also been collected in Samoa and in the Aru Islands. a Its wood is fine-grained 

 and very strong, and is used by the natives for cart shafts. 



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

 lected in 1819 by Gaudichaud. It was described by Miiller of Aargau, first in Lin- 



a Warburg, Beitriige sur Kenntniss der Papuanische Flora, Engler'g Bot. Jahrb., 

 vol. 13, p. 355, 1890-91.
