roots that are close to the surface of the ground and the 

 tree thrives best when planted close to irrigation canals 

 and on sheltered places. Chinese name 'Tchiu shu 1 , mean- 

 ing 'autumn tree.' (Meyer's introduction.) 



Citrus ndbilis deliciosa. (Rutaceae.) 38101. Seeds of a 

 mandarin orange from Lamao, Bataan, Philippine Islands. 

 Presented by Mr. P. J. Wester, Horticulturist in charge of 

 Lamao Experiment Station. "Seeds of a small, oblate, very 

 thin skinned mandarin of most excellent quality, that is 

 imported from China in considerable quantities. It is to 

 my mind greatly superior to all the mandarins I have eaten 

 here or in Florida with the possible exception of the 

 'Oneco', which it very much resembles in flavor. Con- 

 sidering how well the mandarin reproduces itself from 

 seed, at least a few seedlings of excellent quality should 

 be obtained from these seed." (Wester.) 



Citrus hystiix . (Rutaceae.) 38293. Seeds of the cabuyao 

 from Lamao, Bataan, Philippine Islands. Presented by Mr. 

 P. J. Wester, Horticulturist in charge, Lamao Experiment 

 Station. "A thorny tree from 6 to 12 meters in height 

 with a rather dense rounded head, frequently with drooping 

 branches; young growth more or less purplish, smooth. 

 Leaves 16-24 cm. (6-10 in.) long, broadly winged, the area 

 of the wings frequently exceeding the leaf area; fruit 

 variable, from oblate to pyriform turbinate or oblong, 

 smooth, to more or less corrugate, greenish lemon yellow; 

 rind medium thick, flesh greenish, juicy, sharply acid, 

 aromatic, contained in 12 to 15 locules; juice-sacs short 

 and blunt; seeds many, flat, reticulate. Range from 

 Malaysia including the Philippines to India. Like all 

 other Philippine citrus fruits, the cabuyao goes under a 

 multiplicity of names, varying with the tribal languages 

 of the archipelago and the different forms of the fruit; 

 some of these names are Suha, Balincolong, Biasong, Tibu- 

 lit, Colobot, etc. Excepting the citron the cabuyao is 

 perhaps less esteemed than any of the better-known citrus 

 fruits in the Philippines and can scarcely be said to be 

 cultivated. Some kinds are eaten with fish by the Fili- 

 pinos and make a fairly good 'ade 1 . Most forms are also 

 used in cleaning clothes and as a hair wash. The cabuyao 

 has scarcely been introduced beyond its native habitat and 

 is seldom seen even in botanical collections. For at- 

 tractive shapeliness certain forms of the cabuyao are sur- 

 passed by no other citrus fruit. Some of these forms un- 

 questionably will be recognized as subspecies or possibly 

 as separate species on closer study." (Wester, Bulletin 

 No. 27, Citriculture in the Philippines.
