succeeds well even in the low regions of New Britain [R. Parkinson]. 

 Southward Eastern sub-tropical Australia is still adapted for the 

 culture of this important plant. A new prolific variety has come 

 into use in Brazil, the " Maragogyne " [Christy]. In America, 

 Coffee-plantations have suffered not only from the attacks of an 

 erysiphoid fungus, but also the Cemiostoma-fly. Coffee-leaves have 

 recently come into use as a substitute for tea. 



Coffea Liberica, Bull. 



Guinea. The Liberian Coffee-plant, distinguished already by 

 Afzelius. According to Dr. Imray this species has shown immunity 

 from the Cemiostoma-fly, and it is less affected by the Hemileia- 

 mould. It grows to the size of a real tree, is a rich bearer, and the 

 berries are larger than those of the ordinary Coffee-bush but the 

 (useless) pulp is about twice as large in proportion to the seeds. The 

 fruit requires a longer time to ripen (a year), but this species can be 

 grown in hot tropical countries down to the coast [Lietze, Regel]. 

 This species is highly ornamental in foliage and its flowers are 

 deliciously scented. 



Coix Lachryma, Linn<$. 



South-Asia, New Guinea, Polynesia. "Job's Tears." This plant 

 is cultivated for food by the eastern hill-tribes of India and supplies 

 a staple-article of diet to the Tankhul Nagas of Manipur ; it is also 

 grown in Burma. The form cultivated for food has an easily break- 

 able deeply furrowed shell, that of the wild plant being extremely 

 hard and shining. Seeds require long soaking before they are sown 

 [Dr. Watt]. The plant likes humidity ; it comes to perfection at 

 Port Phillip. C. tubulosa (Hackel) is a Papuan species. 



Cola fl.ryiTmirm.tfl., Schott and Endlicher. (Sterculia, acuminata, Beauvois.) 



Western Africa. A small or middle-sized tree, perhaps hardy like 

 many of the allied Sterculias, also outside the tropics in mild regions. 

 In Jamaica it is cultivated up to an elevation of 3,000 feet [W. 

 Fawcett]. It furnishes the famed Cola-seeds, already brought under 

 notice by Caspar Bauhin. They have highly stimulating properties, 

 reminding of those of Coca, and can be made into an agreeable 

 unfermented beverage, against the pernicious custom of indiscrimi- 

 nately treating with alcoholic liquids. Prof. E. Heckel, of Marseille, 

 converts the nuts as " Cola-paste " into an exceedingly concentrated 

 nutritious product [T. Christy]. Used now also for clearing beer 

 [Armstrong]. Medicinally recommended in cases of chronic diarrhoea 

 and of inebriety ; might be tried also in diabetes. The fruits of a 

 second species described by Professor Max. Cornu occur intermixed 

 with the ordinary kind in commerce.
