surface smooth; color greenish yellow to lemon yellow; rind medium thick; 

 pulp greenish, juicy, sharply acid, aromatic; juice sacs rather short and 

 blunt, usually containing a more or less distinct nucleus; seeds usually 

 many, flat, reticulate. 



This fruit, commonly called cabuyao by the Tagalogs in cen- 

 tral Luzon, is without question the "copahan" of Bohol. Near 

 Manila the tree has been found in 

 flower in September, while in Bohol 

 flowers were collected in May. The 

 fruit may be used in making ade, but 

 is inferior to the lemon or lime. The 

 native inhabitants eat it together 

 with fish, and also use the fruit in 

 washing. It is of practically no im- 

 portance. 



The "amongpong," found in Bohol, 

 and considered a distinct fruit from 

 the copahan by the native inhabit- 

 ants, differs chiefly in having only 

 26 to 30 stamens, and a large oblate 

 ovary with a short and slender style. 

 The first has not been examined by 

 the writer and is said to be smooth 

 and short, pyriform, 10 centimeters 

 in diameter. Flowers examined in 

 May. 



"Calo-oy" is another fruit also 

 found in Bohol considered by the in- 

 habitants as distinct from the "co- 

 pahan" and "amongpong." The leaf 

 characters in the calo-oy scarcely dif- 

 fer sufficiently to entitle it to rank 

 even as a subspecies; the flowers 

 were just gone when the visit was 

 made to Bohol. The fruit is said to 

 be globose, smooth and about 8 centi- 

 meters in diameter. 



"Amontay" (PL IV6) is still another form of C. histrix 

 found in Bohol. This plant was also out of its flowering stage 

 at the time of the visit. The fruit, forwarded to the writer in 

 February by Mr. Southwick, is about 88 millimeters in diameter, 

 irregularly globose, with flattened or depressed base, and rounded 

 apex, smooth, lemon yellow; oil cells mostly raised; skin thick; 

 the pulp, contained in 10 to 12 locules, juicy, and rather pleas-
