grown extensively. Seedlings producing excellent fruit, some nearly 
seedless, have been found in several provinces. 
Samuyao, Citrus sp. A small, nearly round fruit, conspicuously dented 
at the apex, growing in Cebu. 
Sua, Citrus sp. An oblately-flattened citrus fruit grown in Cebu and 
other parts of the Visayas, possibly a variety of Citrus medica L. 
Messrs. Wester and Barrett inform us that these 12 forms 
represent only a small percentage of the total. The valid Philip- 
pine species, the natural hybrids, and the introduced species will 
total in the neighborhood of 100 more or less distinct forms. 
Mr. Merrill is of the opinion that various forms of Citrus found 
in the Philippines represent not more than 10 or 12 valid species 
from a botanical standpoint, possibly a less number than this. 
Some of these fruits might be made commercially important, 
but up to the present time only one or two species of Citrus have 
been cultivated in quantities sufficient to make the crops worthy 
of note. Nothing has been accomplished in the improvement of 
species, and very little in the education or encouragement of 
the native growers, and as a natural consequence the few citrus- 
fruits upon the market leave much to be desired, and many of 
the existing orchards present dismal pictures of ignorance, mis- 
management, and neglect. The Bureau of Agriculture is now 
working to remedy these conditions. 
The following investigations were undertaken to determine the 
value of the most promising species and to develop methods for 
their utilization. The manufacture of oil from orange peel 
and of paper from the pulp, and the bottling of orange, lemon, 
and lime juice have been studied in addition to the chemical in- 
vestigations of the fruit. As a result of our studies we believe 
that it will be possible to develop the production of orange- 
peel oil and the bottling of orange and lime juice upon a com- 
mercial basis, but not at the present time. No industry of this 
nature will prove profitable until the practical labor of improv- 
ing the species and the orchards is accomplished. 
THE ORANGE. 
Naranjita (Spanish), sintonis (Tagalog), is a green loose- 
skinned orange of the Mandarin type, Citrus nobilis Lour., a form 
*Mr. E. D. Merrill, chief botanist of this Bureau, offers the criticism 
that the correct name for lime occurring in the Philippines is Citrus 
lima Lunan, C. limetta Risso being a synonym, and that suha, spelled 
sua, above, is a common name in Luzon for the pomelo.
