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' , mean- 
ing 'autumn tree.' (Meyer's introduction.) 
Citrus nobilis 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 hystrix. (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'. 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.
