PLANTS OF ABANDONED CLEARINGS. 59 



(Oestrum pallidum), the lemoncito or orange berry (Triphasia trifo- 

 liata), and the piod or beach plum (Ximenia americand), which they 

 spread in the same wa}^. Pineapples continue to grow for years where 

 they are planted, and in old garden spots are found plants of the intro- 

 duced arrowroot (Maranta arundinaced) (PL XXV), the 'native arrow- 

 root (gabgab), Taeca pinnatifida, turmeric, wild and cultivated ginger, 

 and the cassava plant, or mandioca (Mcmihot manihot). Among the 

 trees and shrubs which do not spread of their own accord in Guam are 

 the tamarind, the cashew nut (Anacardium, occidentale), the tree which 

 in Honolulu is called the "golden shower" (Cassia fistula], the pome- 

 granate, the scarlet hibiscus, and the ornamental Phyllaureas, Aralias, 

 and Acanthaceae of the gardens. It is interesting to note that of the 

 three Annonas introduced into the island the custard apple or bullock's- 

 heart (A. reticulatd) is the only species found wild, the soursop 

 (A. muricata) (PI. XXXIV), and the sweet-sop or sugar apple (A. 

 squamosa) (PL XXXV), growing only where planted. 



Among the plants which on account of their sterility must be planted 

 by man are the textile screw pine or aggag (Pandanus tectorius}, 

 only one sex of which grows on the island; the seedless breadfruit 

 or lemae (Artocarpus cornmunis)', taro (Caladium colocasia) and yams 

 (Dioscorea spp.), which are seldom known to produce seed; sweet 

 potatoes, which are propagated by cuttings, and bananas and plan- 

 tains, which are seedless and must be grown from root suckers. 

 Young plants of Agave vivipara, which the natives call " lirio de palo " 

 or the "tree lily," are often found growing in circles, with the dead 

 mother plant at the center. 



Whole fields are overgrown with guava bushes, just as in the 

 Hawaiian Islands and many other tropical countries; but the common 

 lantana (Lantana camara) and the sensitive plant (Mimosa pudica), 

 which are pests in so many parts of the world, have, fortunately, not 

 yet found their way to Guam. 



Among the plants which have escaped from gardens are the pretty 

 blue pea (Clitoria ternated)', the crimson-flowered cypress vine (Qua- 

 moclit quamoclit), which the natives call "angel's hair" (cabello del 

 angel); Lochnera rosea, sometimes known as the Madagascar peri- 

 winkle; the marvel of Peru, or four o'clock ( Mirabilis jalapa), and 

 the touch-me-not or garden balsam (Impatiens balsamind). Tomatoes 

 bearing small fruit, either oval or globular, are also found growing 

 near abandoned gardens, and occasionally gourd vines (Lagenaria 

 lagenaria) are seen bearing bottle-shaped fruit. 



On the edges of clearings, growing in partial shade, are two bur- 

 bearing plants called "dadangse" (stickers) by the natives: Urena 

 sinuata, a malvaceous shrub with five-lobed leaves and rose-purple 

 flowers, and Triumfetta rhomboidea, belonging to the Tiliaceae, with 

 simple leaves and inconspicuous yellow flowers. The fruit of both is
