50626. (Coffea arabica maragogipe Froehn. 



This variety is distinguished by the larger size and thicker character 

 of the leaves and fruit, and in these points it tends toward Coffea liberica. 

 It was discovered by Crisogono Jos6 Fernandez in 1870, and because of the 

 fine flavor of the beans has been introduced into Brazil and the ICngUsh 

 colonies. (Adapted from Engler, Botanische Jahrbiicher, vol. 25, p. 263.) 



50627. Coffea arnoldiana Wildem. 



A Belgian Kongo plant with deep-green obovate or oblong leaves, shining 

 above, becoming a deep reddish brown when dry. There are one to five 

 flowers to an involucre in the axillary inflorescence; the calyx is glossy and 

 the disk prominent in the fruit. (Adapted from Wildeman, Mission Emile 

 Laurent, p. 325.) 



50628. Coffea aruwimiensis Wildem. 



A sturdy tree with oblong or oblong-lanceolate leaves, obtuse at the 

 apex, the tip shortly acuminate, cuneiform at the base, brown when dry, 

 paler beneath. The flowers with short involucres are in axillary globular 

 clusters. The persistent sepals completely inclose the fruit, which is 

 surmounted with a short cylindrical disk. The inflorescence is covered 

 with a thick varnish, which is shining when dried. Native to Belgian 

 Kongo. (Adapted from Wildeman, Mission Emile Laurent, p. 321.) 



50629. Coffea canephora sankuruensis Wildem.

 base and summit, dull and paler beneath, shining above. The 5-parted 

 flowers are in dense cymes united in a common involucre of which the 

 stipulelike bracts are triangular and keeled. There are three to four 

 inflorescences in each leaf axil. The fruits, with one or two seeds, are in 

 dense, almost sessile clusters. (Adapted from Wildeman, Mission Emile 

 Laurent, p. 330.)

A Belgian Kongo plant with leaves 20 centimeters long and inflorescences 

 either solitary or two or three in each leaf axil. The bracts enveloping the 

 inflorescence are short and linear or long and broad. The flowers are five 

 or six parted. A fruiting cyme may bear five slender-pediceled fruits in 

 a cluster. The fruiting pedicel is always longer than the bract. (Adapted 

 from Wildeman, Mission Emile Laurent, p. 335.) 



50631. Coffea dewevrei Wildem. and Dur, 



A tree 15 meters high with shining gray bark and obovate-elliptic leaves,
