CITRUS FRUITS IN THE PHILIPPINES. 15 



petiole 24 to 38 millimeters long, with narrow wing margin, in large leaves 

 sometimes 17 millimeters broad; flowers not seen; fruit roundish oblate, 

 about 45 millimeters across, somewhat corrugate, 8 loculed. 



Budwood and fruits of the cabugao were forwarded to the 

 Bureau by Mr. A. M. Burton, from the Mountain Province. 

 The writer did not have the opportunity of examining the fruit, 

 of which, however, an excellent photograph was made, and, 

 to date of writing the plants at Lamao not having bloomed there 

 has been no' chance to examine the floral characters. The 

 general character of the plant and fruit indicates that the 

 cabugao is a form of the alsem. 



Through a typographical error in Bulletin No. 27, Plate XVI 

 (a), the cabugao is credited to Bohol. 



B. A. No. 2266 (Benguet, Mountain Province). 



Citrus longispina. TALAMISAN. 

 (Pis. Ha, Ilia.) 



An arborescent, very thorny shrub about 5 meters tall, with numerous 

 suckers and interlocking branches, the spines on the stems frequently 10 

 centimeters long; young growth bright green, nearly always angular; 

 leaves 6.5 to 10 centimeters long, 3 to 4.8 centimeters broad, ovate to 

 broadly elliptical, crenate; base obtuse to broadly acute; apex acute to 

 rounded, usually emarginate; petioles 19 to 25 millimeters long, rather 

 narrowly winged, though in large leaves the wings are up to 18 milli- 

 meters broad; flowers not seen; fruit roundish, somewhat flattened at 

 apex, 58 millimeters in diameter, smooth, deep lemon colored; skin thin; 

 locules 11 to 15; pulp very juicy, mildly acid, with a tinge of orange yellow, 

 aromatic and pleasantly flavored; juice cells large, plump, blunt or pointed 

 at one end; seeds rather few, of medium size, fairly plump, more or less 

 reticulate, polyembryonic, and of poor germinating qualities. 



The talamisan is exceedingly rare, and is found in cultivation 

 in Bohol (one plant has been seen in Cebu) and is fairly produc- 

 tive. Excepting the mandarin, which is also of rare occurrence, 

 it is much superior to all other citrus fruits grown in these two 

 islands, and is eaten by the inhabitants; it is nevertheless very 

 rare and of no economic importance at present. The fruit 

 ripens in January and February, and is a poor keeper. Intro- 

 duced into cultivation, the fruit of the talamisan could to ad- 

 vantage be used as an ade fruit, and with a little sugar it would 

 make a good breakfast fruit. The dense growth of the plant, 

 with numerous suckers, armed also with formidable spines, 

 would make it a good live fence. 



The talamisan, or tamisan as it is also called, is one of the most 

 interesting citrus fruits that has come to the attention of the 

 writer. Its angular growth, formidable spines, broad, some-
