02 USEFUL PLANTS OF GUAM. 



he said to lie (•(Hiipanilivcly simple w i(h llic (iws of triii|»erate cliniateH, wlioro forests 

 are nmiparativeiy oi»eii and lietjueiitiy coiiiiKWed of only a few kinds of trees or, 

 perhaps, of a sinj^le species. In the Tropics a natural forest of one species is practi- 

 cally unknown; Imndreds of kinds grow indiscriminately mixed together. Crowded 

 logctlicr in tropical forests trees have nothing like the shapes or hal)itH they would 

 assume if standing alone. All an- ]tutliMg forth, as it were, their hest efforts to grow 

 tall :tii<l thus secure as niucli sunlight as possible. Tlu'ir leaves and hranches are 

 inextricably confused, interlaced with clindiing plants, and encuml)ered with ])ara- 

 sites and eitiphytes. To cut down a particular tree may be impossi])le unless one is 

 willing to clear a large neighboring area to permit it to fall. Unless the })otanist 

 finds a clearing his opportunities for securing even the desired fragments of branches 

 with leaves, flowers, and fruit may be extremely few. Hence, our knowledge of 

 tropical trees is still in the early pioneer .stages." 



Amonof the trees mentioned by Gaudicliatid under their vernacular 

 names arc the itil, fa^o, aahan, chopag-, chuti (tchiuti), seyati (sidjiati), 

 kadehi, hiuoiti, liodda (odda), tagcte (tagaiti), nunii, liayun-lago; and 

 in the list of woods forwarded by Governor Olive to the captain -gen- 

 eral of the Philippines are agatelang, agaliyan-halonitano, aguanac, 

 ahgao, alom, amahayan, angilao, aplokhating, brea, chosgo, faka, fago, 

 fafiog, gausale, guaguaot, gulos, hayunmananas, ha3'un-palaoan, lalaha, 

 lalanyog, langiti, lana, lenaya, luluhut, makupa, mahlokhayu, mapuiiao, 

 nimo, fiolon, paepac, palma brava, panago (or banalo), pengua, kelitae 

 (or palaga-hilitae), sayafo (or seyafe), sumai, sumaclacla, umumo, 3'oga. 

 Only a few of these trees have been identified. Good specimens of 

 all are desirable for herbaria. 



Among the unidentified shrubs are several species which Gaudi- 

 chaud referred to the genus Pavetta, called ,by the natives " utud," 

 "otud" or "utug," "sesbu" or "sosbu," and "guaguabug." Another 

 shrub not 3^et determined, having a disgusting fetid odor and flowers 

 growing in axillary and terminal umbels, is called by the natives 

 "pau-dedo." 



GROUPS WHICH ARE NOT WELL KNOWN. 



Certain families of plants have not been well worked up, such as the 

 Apoc3^naceae, Rubiaceae, Verbenaceae, Urticaceae, and Pjuphorbiaceae. 

 Among the first there are certain seaside shrubs allied to Cerbera 

 referred to by Gaudichaud under the name of Rauwolfia and Pluniiera. 

 One of these is probably Ochrosla »iar!annensls^ but the others are not 

 yet known. Among the Rubiaceae are .several small shrubs allied 

 to the genus Ixora. Among the Verbenaceae the Guam plants belong- 

 ing to the genera Premna and Vitex should be compared with series 

 from other localities, and it is probable that there is a second species 

 of Clerodendron, with bitter leaves, which has not 3^et been recorded. 

 There are several species of Phyllanthus, Euphorbia, and Glochidion 

 which have not yet been collected as well as a few Myrtaceae.
