DIFFERENT VARIETIES OF COCOA 7 



rather deeply ribbed. Mature fruits of a clear yellow 

 colour, short, length only from 10 to 12 cm. (4 to 4| in.), 

 almost spherical, perfectly round at both extremities, 

 and even sometimes a little depressed at the summit. 

 Surface smooth, showing ten ribs well marked in the 

 upper part, but disappearing towards the centre ; the 

 lower half is completely round, without furrows. 



Habitat ; common in cocoa-plantations in San Thome. 



Distinguishing Features of the Forastero and Criollo 

 Varieties. For convenience of reference attempts have 

 been made to divide up the varieties of T. cacao into 

 three divisions, which have been named respectively 

 Forastero, Criollo, and Calabacillo. The varieties in- 

 cluded under the Forastero and Calabacillo divisions 

 are more robust than those belonging to the Criollo 

 division, and are generally more hardy. The several 

 varieties are, however, best differentiated by the char- 

 acters of their fruits and beans. The different forms 

 which the fruits of the Forastero varieties assume are 

 clearly shown in Plates 1 and 2, which are repro- 

 duced from photographs recently taken by the writer 

 in San Thome. The fruits marked respectively I, II, 

 m, and iv all belong to the Forastero division, and 

 clearly show the extraordinary manner in which they 

 differ in size and form. Fruits marked i, n, and iv 

 are fairly representative of the varieties generally classi- 

 fied as Liso Colorado, Liso amarillo, and Amelonado. 

 The fruit marked in is a form of Amelonado which the 

 writer proposes to distinguish as Amelonado pequeno, 

 and that marked vi is a fruit representative of the 

 Calabacillo division. If each of these varieties con- 

 stantly produced the form of fruit by which it has been 

 here distinguished, identification would be an easy 

 matter ; but this is by no means the case, for the forms 

 of fruit on a single tree frequently show such variation 

 that it is possible to select fruits representative of two 

 or even three of these varieties. Again, the colour of 

 the fruits of a particular variety is also inconstant, as 

 it varies from red to bright yellow, and it is not un- 

 common to see both red and yellow fruits on the same 

 tree. 



The fruits of the Criollo varieties likewise exhibit 

 similar diversities in form, size, and colour. The differ-
