44 SHADE IN COFFEE CULTURE. 



For the sake of ready reference all the common names used for 

 shade trees and crops grown with coffee in the various coffee regions 

 have been introduced in the form of an alphabetical index. 



Acacia albicans. 



Common name. — Huizache (Mexico). 

 This species is said to be desirable because it produces a moderate shade, "with its 

 small leaves and elevated top." Gomez objects to it, however, on the ground that 

 it stains the leaves of the coffee tree, though the extent and nature of the injury are 

 not explained. 



Acacia angico. (See Piptadenia colubrina.) 



Acacia julibrissin. (See AJMzzia julibrissin.) 



Acacia montana. 



A tree native in the mountains of Java; recommended for coffee shade according 

 to van Gorkam. 



Acacia virginalis. (See Piptadenia colubrina.) 



Acajou. (See Anacardium occidentcde.) 



Acajou amer (Guadeloupe). (See Cedrela odorata.) 



Acajou de Saint Domingue (Guadeloupe). (See Swietenia makagon i). 



Acajou du pays (Guadeloupe). (See Cedrela odorata.) 



Achiote (Spanish America). (See Bixa orellana.) 



Acrocarpus fraxinifolius. 



Common name. — Howlige (Coorg, India). 

 A leguminous forest tree left standing for shade in coffee plantations. (Cameron. ) 



Acupa (Colombia). (See Hum crepitans.) 



Adenanthera pavonina. 



Accordiug to Morren this species, though little known for coffee shade, has several 

 very desirable qualities. The leaves are dropped twice in the year, at the beginning 

 and at the end of the rainy season, but the new foliage appears in a few days. The 

 leaves close at night like those of Pithecolobium soman, permitting access of air and 

 dew; the roots are deep; the wood is hard, of beautiful color, and suitable for cabinet- 

 work. It is not stated, however, that the present species excels in rapid growth. To 

 insure prompt germination the seeds need to have the outer shell cut or filed through 

 and to be soaked in water from six to twelve hours. 



Agati grandiflora. 



Synonym. — Sesbania grand [flora. 



Common names. — Baculo (Porto Rico); Gallito (Porto Rico). 

 This beautiful leguminous ornamental, though growing to a height of from 10 to 20 

 feet and becoming a small tree in size and form, is scarcely more than herbaceous in 

 structure and lives but a year or two. In India the bark is used as an astringent med- 

 icine, while the leaves, flowers, and fruit are used as a vegetable or as an ingredient 

 of curries. The leaves and shoots are also eaten by cattle. The bark also yields a 

 fiber and the trunks serve for firewood and as a substitute for bamboo. From the
