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 (Jalropha curcas) or textile screw-pines 

 (Pandanus tectorius) . 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 trifoliata), sappan wood (Biancaea sappan}, and the lead tree (Leu- 

 caena 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. 



Acacia farnesiana. Aromo; used occasionally. 



Agati grandiflora. Sometimes used; large flowers and long legumes edible; in 



Guam called ' ' katiirai. " ( PI. VI. ) 



Bambusa sp. Piao; if placed in the ground green, the stems root at the nodes. 

 Biancaea sappan. Sibukao; often used. 

 Citrus hystrix acida. The lime (called "limon"); often used, forms dense 



hedges; always full of fruit. 

 Citrus medica limon. The lemon (called "limonreal"); fine for hedges; always 



full of fruit. 

 Erythrina indica. The coral tree (called "gabgab"); green stakes root readily; 



flowers bright red. 

 Jatropha curcas. Physic nut (called in Guam "tubatuba"); very often used; 



green branches root readily. (PL LV. ) 

 Leucaena glauca. The acacia-like lead bush, or lead tree (called in Guam "tan- 



gantangan" ); one of the commonest hedge plants; cattle will not eat it. 

 Pithecolobium dulce. Kamachiles; pods eaten by cattle, bark used for tanning. 

 Triphasia trifoliata. Orange berry (in Guam called ' ' lernoncito " ) ; forms dense, 



thorny hedges. 



Fennel. See Foeniculum foeniculum. 

 Ferns. 



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

 widely spread aquatic Ceratopteris thalictroides(L.) Brogn., 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 alambrillo, or wire fern, which reappears on the undrained, 

 treeless, savanna lands, and Lygodium circinatum (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 

 haenkei 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. ( ' ' lagrigayao " ) (PI. IV) and by Belvisia 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 Antrophyum plantagineum 

 Kaulf., and by Vittaria elongata 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, Cydophorus adnascens (Sw.) Desv. (PL XLVII) , also climbing, but with small 

 linear-lanceolate or linear fronds, and Microsorium 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 quadriaurita Retz., and Pteris biaurita L. ; 

 tne Asplenieae by Blechnum orientale L., Asplenium falcatum Lam., A. laserpitiifolium 

 Lam., A. monanthemum L., A. nitidum 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 dissecta (Forst.) Kuntze, and D. parasitica (L. ) Kuntze; and the Davallieae 

 by Odontosoria 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. hirsutula (Sw. ) Presl, the long, narrow, simply pinnate fronds of which
