DESCRIPTIVE CATALOGUE. 371 



sparse sprinkling of ironwood ( Casuarina equisetifolia) . Among the ferns are Gleiche- 

 nia dichotoma, Blechnum orientale, Odontosoria retusa, Pterin biaurita, Pteris marginata, 

 and Lygodium scandens. The coarse labiate Mesosphaerum capitatum ("batunes"); 

 Glossogyne tenuifolia, a composite like Bidens; and the yellow-flowered Stemmodontia 

 biflora and S. canescens occur, the last with thickly canescent leaves. Among the 

 shrubs are Lobelia koenigii and Pemphis acidula, and the grasses include Dimeria 

 chloridiformis, a small variety of Echinochloa colonum, Panicum distachyura, and Cen- 

 totheca lappacea. The little yellow-flowered Hypoxis aurea grows on the mountains 

 back of Agafia, and on Santa Rosa are patches of Lycopodium cernuum. 



Sayafi or sayiafi. 



An urticaceous shrub or small tree resembling Boehmeria. Collected by Gaudi- 

 chaud but not identified. Also written "i sedyiafi," "i seyafi." 

 Scaevola koenigii. Same as Lobelia koenigii. 

 Scaevola velutina. Same as Lobelia koenigii. 

 Schizophyllum. See Fungi. 

 Schychowskya interrupta. 

 Family Urticaceae. 

 Local names. — Palilalia (Guam); Mangeso (Samoa); Salato-nithoro (Fiji). 



An annual nettle-like herb with deep green, long-petioled alternate leaves, which 

 are 3-veined at the base, and clusters of small green unisexual flowers borne on long 

 slender peduncles. Stem 60 to L20 cm. high, erect, flexuous, branched, furrowed; 

 whole plant more or less covered with scattered stinging hairs; leaves 6 to 9 cm. 

 long, broadly ovate, acuminate, coarsely crenate-serrate, membranous, base cuneate, 

 rounded or cordate, 3 to 5- veined, lateral veins 3 to 5 pairs; petiole long, very slen- 

 der; stipules connate in j>airs; flowers in cymes or spikes which are very variable, 25 

 cm. long, bearing rather distant pedicelled clusters of minute flowers; flower branches 

 short, or long and very slender; male sepals 4, concave; pistillode minute; female 

 flower with pedicel decurved, swollen above; achene cordate, compressed, keeled on 

 one side, the keel decurrent on the pedicel. Common in cultivated fields and waste 

 places. A weed widely distributed throughout the East Indies, China, Abyssinia, 

 and the Pacific islands. Easily distinguished from the following species by its acu- 

 minate leaves and the hairs on the stem and leaves. Although this plant bears a 

 bad reputation in Fiji, and in Samoa, where its common name signifies "stinging," yet 

 in Guam it is comparatively harmless. It bears a close resemblance to S. aestuans 

 (Fleurya aestuans Gaudich. ), which in Porto Rico is called "picapica."

The type species of Fleurya belongs to the earlier genus Urticastrum, and the name 

 Fleurya must therefore be abandoned. 

 Schychowskya ruderalis. 



An annual glabrous herb with leaves 3-veined at the base. Leaves alternate, 

 obtuse, truncate, or subcordate at the base, ovate, scarcely acuminate, coarsely 

 crenate-serrate or crenate, 2.5 to 10 cm. long; flowers unisexual, in androgynous 

 clusters which are shorter or longer than the petiole; tufts loosely flowered, approxi- 

 mate; pedicels not dilated; male flowers 3 to 5-sepaled; stamens 3 to 5, inflexed in 

 bud; pistillode small; female flowers with 4-lobed or 4-parted perianth, posticous 

 lobe largest; ovary oblique, decurved, style subulate, very short, ovule erect; achene 

 half inclosed in the persistent perianth, obliquely ovate, compressed, gibbous, 

 pericarp membranous, endosperm scanty, cotyledons broad, radicle short, straight.
