rather small, rounded or cuneiform toward the base, acuminate at 

 the apex; petiole thick, 15 mm. long; blade up to 25 cm. long by 10 

 cm. wide; paired lateral veins 10 to 13, usually 12, stout and promi- 

 nent on both surfaces. Inflorescences in compact heads with double 

 calycules surrounding i to 6 flowers, commonly 4 in one group. 

 Flowers 5-merous ; corolla-tube 5 mm. long in adult flowers, about 

 as long as the corolla-lobes, occasionally longer. Fruit i cm. long, 

 furrowed, nearly sessile ; seed 7 mm. long by 4.5 mm. to 5 mm. wide, 

 distinctly smaller than the seeds of C. canephora Pierre ex Froehner. 



Diagnostic Characters of the Variety. — Leaves vary, on different 

 specimens and on the same plant, from a rounded to a cuneiform 

 base. Leaves are longer, more elliptical, with more accentuated cross 

 veins than in C. canephora Pierre ex Froehner. Corolla is as large 

 as that of C. canephora Pierre ex Froehner but the lobes are usually 

 a little longer than corolla-tube in this variety. 



Geographical Distribution : — Indigenous in Mayomke and Kouilou. 

 Cultivated in Luvituku and Mayomke, Gabon, and especially along 

 Kouilou. 



History: — This variety was collected by R. P. Klaine (No. 1928a) 

 in August, 1900, and (No. 1928b) in January, 1901, in Gabon. 

 M. Pierre distinguishes three subvarieties ; namely, C. canephora 

 Pierre ex Froehner var. kouilouensis Pierre mss. ex DeWild. sub- 

 varieties grisea, flavescens^ and iati folia which are separated mainly 

 on the leaf characteristics of hue and size, both of which are tre- 

 mendously variable in this variety and species; so much so that I 

 hardly consider it justifiable to utilize these distinctions in this regard. 

 This variety itself deserves and is receiving Increased attention in 

 cultivation. 



Use: — As a substitute for the seeds of C. arabica L.
