Fence and hedge plants. 



The following are the most common plants used in Guam for inclosing garden 

 patches. Large fields and plantations are seldom inclosed, but are defined by rows 

 of coconuts, or by lines of physic nut bushes {Jniropha curcas) or textile screw-pines 

 {Paudanus tectoriiis) . A prickly pear (Opuntia) and an Agave have been intro- 

 duced, but they have not established themselves. On the other hand, the orange 

 berry {Triphasia irifoliata), sappan wood {Biancaea sappan), and the lead tree {Leu- 

 caci}(( glauca) have in places spread into thickets. Lawsonia alba, the Egyptian privet, 

 or henna, a favorite hedge plant in some countries, grows well in Guam, but the 

 natives do not use it for hedges. See under Gardens.

 Ferns. 



Among the true ferns, or Filicales, the Ceratopteridaceae are represented by the 

 widely spread aquatic Ceraiopteris thaUctroides (L.) Br ogn. , the fronds of which in Japan 

 are eaten as a pot herb; the Schizaeaceae by the climbing marsh fern Lygodium scan- 

 dens Swartz, called also alamhrillo, or wire fern, which reappears on the undrained, 

 treeless, savanna lands, and Lygodium circinatain (Burm. ) Swartz, the stems of which 

 are braided by the Filipinos into hats; the Gleicheniaceae by Gleichenia dichotoma 

 (Hook.), (PI. L) (see in place); and the Cyatheaceae, or tree-ferns, by Alsophila 

 haenkel Presl, which grows along the banks of streams in the forests. In the family 

 Polypodiaceae the Acrosticheae are represented by the great simply pinnate marsh 

 fern Acrostichum aureum L. ( " lagiigayao " ) (PI. IV) and by Belriskt spicata (L.) 

 Mirbel, a species with simple fronds, on the contracted apex of which the spores are 

 borne; the Vittarieae by the simple-fronded, plantain-like Anfrophyuni plantagineum 

 Kaulf., and by Vittaria ckmgata Swartz, which grows like tufts of grass on the limbs 

 and trunks of trees; the Polypodieae by the climbing Phymatodes phymatodes (L. ) 

 Maxon (PI. LXIII), called "kahlau" or "kahlao," with fronds like huge lobed oak 

 leaves, Cyclophorus adnascens (Sw.) Desv. (PI. XLVII), also climbing, but with small 

 linear-lanceolate or linear fronds, and Microsoriuin irioides (Lam.) Fee., a terrestrial 

 species with large broadly linear or sword-shaped fronds dotted with sori on the back; 

 the Pterideae by Pteris marginata Bory, Pteris qnadriaurita Retz., and Reris hlaurita L. ; 

 tne Asplenieae by Blechnum urkntale L., Asplenium falcatum Lam., A. laserpitiifolimn 

 Lam., A. monanthemum L., A. nilidum Sw., and the great epiphytal " bird's-nest fern," 

 Neottopteris nidus (L.) J. Sm., in Guam called ".galak" or "galag," the sword-like 

 simple fronds of which are called " sables" by the Filipinos; the Dryopterideae by 

 Dryopteris dissecia (Forst. ) Kuntze, and D. parasitica (L.) Kuntze; and the Davallieae 

 by Odnntosoria retusa (Cav. ) J. Sm. and Schizoloma ensifolium (Sw. ) J. Sm., which 

 grow on the savannas, the epiphytal Nephrolepis acuta (Sw.) Presl and the closely 

 allied N. Itirsiitula (Sw.) Presl, the long, narrow, simply pinnate fronds of which
