Var. MIARAY (Wester) comb. nov. 
Citrus miaray Wester in Philip. Agr. Review 10 (1917) 457. 
Mindanao (Bukidnon), Wester. Cultivated. 
Local name: Miarai (Buk.). 
Citrus miaray Wester, here reduced as a variety of C. aurantifolia 
Swingle, is probably a hybrid between C. aurantifolia and some other 
species. Of Wester’s species I have seen only specimens with very young 
fruits. Citrus excelsa Wester is apparently also a hybrid with C. auran- 
tifolia Swingle as one of its parents.

Citrus longispina Wester, whieh I refer to C. aurantium Linn., is perhaps 
hybrid between Citrus aurantium and some other species.

Northern Luzon to Palawan and Mindanao, in most or all islands and 
provinces. In secondary and primary forests, sometimes in or near settle- 
ments, at low and medium altitudes, often rather common and truly native 
of the Archipelago. Widely distributed in the Malayan region.

The type of Citrus hystrix DC. (histrix) was a sterile specimen from 
a tree cultivated at Montpelier, originating in Mauritius. It may well have 
been of Malayan origin. Citrus papeda Hassk. is doubtless the same.

Bohol, Wester 4824, 2525, cultivated. This is clearly but a slight variant 
of C. hystrix DC. and is apparently very close to if not identical with 
Citrus celebica Koord. in Meded. Lands Plant. 19 (1898) 370, 639, Koorders
