SHADE TREES AND CATCH CROPS. 55 



Congo-pea. (See Cajamis 1 adieus.) 



Coral tree. (See Erythrina umbrosa, also Erytlirina poeppigiana.) 



Cotton. (See Gossypium.) 



Cowpea. (See Vigna catjang.) 



Dadap (Java). (See Erythrina subumbrans, also E. lithosperma.) 



Dadap djangoen. (See Erythrina lithosperma.) 



Dadap minjak (Java). (See Erythrina lithosperma.) 



Dadap serap (Malay). (See Erythrina indica.) 



Dapap solo (Java). (See Erythrina indica.) 



Dalbergia latifolia. 



Common names. — Biti (Coorg, India); Blackwood (British India); Rosewood 

 (British India.) 



In the Coorg district of western Hindustan the planting of coffee under forest 

 conditions has been undertaken to avoid the attacks of the parasitic fungus Hemileia. 

 The native trees which are thought to compete to the detriment of the coffee are cut 

 away; the others, and particularly the deciduous species, are left for protection. 

 Among these Dalbergia is the favorite, perhaps because of its valuable wood, but 

 also probably on account of the fact that, as a member of the Leguminosae, it assists 

 in maintaining the fertility of the soil. 



According to Cameron, some Coorg planters reject this in favor of the Australian 

 tree Grevillea robusta, but the custom of planting or permitting the growth of a large 

 variety of shade trees seems to be general, and there are no accounts of experiments 

 to determine their relative value. 



Dalbergia sissoo. 



A native of British India recommended by Cameron for shading coffee in stony 

 land, and said to flourish in the vicinity of Bangalore. 



Desmodium. (See Meibomia.) 



Dhal. (See Cajanus indicus.) 



Dioscorea. Yam. 



The tropical yam, of which there are numerous species, has been planted as a 

 catch crop with coffee, but would seem to be very poorly adapted to the purpose, 

 although the vines of the varieties not trained upon poles might cover the ground 

 and serve as a protection against drought. 



Dissochaeta cyanocarpa. 



Family Melastomataceae. A tree native in the Malay region; enumerated by Raoul 

 among those which have been recommended for coffee shade. It has also been used 

 for forest planting. According to the Index Keivensis, this species is a synonym of 

 Anj)lectrum glaucum. 



Djeundjing laut (Java). (See Albizzia moluccama.) 



Djohar (Malay). (See Cassia fiorida.) 



Djuas (Java). (See Cassia fiorida.) 



Dobera. 



Species of this genus of Salvadoraceae are used, according to Lecomte, for shading 

 coffee in Arabia.
