In this attempt at classifying the principal seedling mangos of 

 Cuba, an effort has been made to recognize relationship and degree 

 of relationship as well. The first and broadest division is there- 

 fore into groups for which I have used the term race; the second 

 is into types, of which several may be comprised in one race. This 

 classification has been made necessary by the fact that the manga 

 hlanca and manga amarilla of Cuba, though quite distinct, are evi- 

 dently more closely related to each other, judging by characteris- 

 tics of growth, inflorescence and fruit, than they are to any fruits 

 of the mango race. As they are seedlings, however, we cannot ap* 

 ply the term variety to them, and I have, therefore, termed them 

 types. Some of these types correspond to the divisions Prof. Rolfs 

 has termed groups, but for seedling fruits I believe the term type 

 is better. The word group rather implies an assemblage of related 

 horticultural varieties or forms, while these seedling types such as 

 manga amarilla, as seen in Cuba, are so constant that the term 

 group does not seem fitting. In considering horticultural varieties, 

 however, it would seem more natural to throw them together into 

 groups, each group containing a number of allied varieties, or those 

 having several characteristics in common. There is naturally some 

 slight variation within each type and any of these variations, if 

 propagated asexually (by budding or grafting) would constitute 

 a true horticultural variety. 



This classification would comprise, then, three divisions ; the first 

 and broadest one is races, the second seedling types, several of which 

 may be included in one race, and the third horticultural varieties, 

 which are propagated by budding or grafting, and of which sev- 

 eral may be included in one type. 



Key to the Principal, Cuban Mangos. 



A. Tree erect, height 60 to 70 feet ; crown open, oval or ovate 

 in form; panicle 8 to 12 inches long, the axis rather 

 slender, reddish maroon ; fruit strongly compressed 

 laterally, with curved and beaked apex, color yellow, 

 often blushed with crimson, the fiber long and coarse ; 

 season June to July. 



Race 1. Mango. 



AA, Tree not erect, but spreading, height only 35 to 40 feet; 

 crown not open, but dense, not oval or ovate but dome- 

 shaped or flat-topped ; panicle shorter, 6 to 10 inehei 

 long, the axis very stout, pale green, tinged red- 

 dish; fruit not strongly compressed, very plump, the 

 beak wanting, color yellow to orange without reddish 

 blush, fiber long and fine ; season July to August. 



Race 2. Manga. 



B. Fruit elongate, oval to ovate, deep orange-yellow, the 

 flesh bright orange. 



Type 1. Manga amarilla.
