" A shrub with compressed branchlets, ovate-elliptical, leathery leaves

 by small orange-colored fruits." (Tutcher.) 



Distribution. — Found on the wooded hills in the vicinity of Hongkong, 

 China. 



"The Hongkong kumquat (Fortunella hindsii) differs from the round 

 kumquat (F. japonica), the oval kumquat (F. margarita), and the 

 Meiwa kumquat (F. crassifolia) in a number of morphological characters, 

 some of them of decided taxonomic significance in this group. It may be 

 regarded as constituting a new subgenus. 



"Protocitrus Swingle. Differs from Eufortunella (1) in having the 

 ovary hypoinerous (3 or 4 celled, not 5 celled) ; (2) in the ovary wall 

 of the mature fruits having on the inside between the stalks of the pulp 

 vesicles a number of minute wartlike pale-yellow, cellular masses; (3) 

 in having the dissepiments of the fruit dry and the peel thin and not very 

 fleshy; (4) in having shorter, broader, more brachytic flowers; (5) in 

 having leaves with the veins more prominent on both faces, and less 

 pallid below. 



"The two most important characters distinguishing the subgenus Pro- 

 tocitrus from Fufortunella are the few-celled ovary and the dimorphic 

 emerg< ncen from the ovary wall of the fruit, viz. ordinary pulp vesicles 

 and verruciform tufts of loosely aggregated more or less colored cells. 



"The Hongkong kumquat. which, as already indicated, is the sole 

 Species el' the subgenus Prolocilrux, may be described as follows: 



"A spiny shrub or small tree; twigs slender, angled when young; 

 leaves oval-elliptical, tapering sharply at both ends, dark green above and 

 faintly venose, paler and venose below; petioles winged, often merging 

 Into the lamina of the leaf without a separative joint. Flowers short,
