176 MANUAL OF TROPICAL AND SUBTROPICAL FRUITS 



lished by W. E. Safford in the Standard Cyclopedia of Horti- 

 culture. This comprises the following five forms : 



Finger-printed (botanically known as forma impressa). Called in 

 Costa Rica anona de dedos pintados. The fruit is conoid or subglobose 

 in shape, and has a smooth surface covered with U-shaped areoles 

 resembling finger-prints in wax. Many seedlings of this type are of 

 good quality, and contain few seeds. 



Smooth (forma Icevis). Called chirimoya lisa in South America 

 and anon in Mexico City. This form is often mistaken for Annona 

 glabra and A. reticulata because of the general appearance of the fruit 

 and on account of the name anon, which is also applied to A. reticulata. 

 One of the finest types of cherimoya.

Tuberculate (forma tuberculata) . One of the commonest forms. 

 The fruit is heart-shaped and has wart-like tubercles near the apex of 

 each areole. The Golden Russet variety belongs to this group. 



Mammillate (forma mamillata). Called in South America chiri- 

 moya de tetillas. Said to be common in the Nilgiri hills in southern 

 India, and to be one of the best forms grown in Madeira. 



Umbonate (forma umbonata). Called chirimoya de puas and anona 

 picuda in Latin America. The skin is thick, the pulp more acid than 

 in other forms, and the seeds more numerous. The fruit is oblong- 

 conical, with the base somewhat umbilicate and the surface studded 

 with protuberances, each of which corresponds to a component carpel. 



Hybrids between the cherimoya and the sugar-apple (Annona 

 squamosd) have been produced in Florida by P. J. Wester and
