December or January. No care is given the crop after 
the sowing. 
54290. 'Nang-dum. ' A recent introduction from Cam- 
bodia. Of the floating rice group, this is the only va- 
riety which yields white, fine rice; it requires only 
a medium amount of water. The grain falls easily from 
the short head. 
54291. ' Song-Ion. ' The oldest variety , extensively 
distributed from Cambodia. The large thick grains are 
in heads 7 to 9 inches long. 
54292. 'Nang-Rum-Nho. ' A variety from Saigon with 
a normal growing period of 120 days .maturing from De- 
cember 20 to January. 5, with a normal yield of 1,500 to 
2,167 kg. per hectare (1,379 to 1,932 lbs. per A.). 
Persea americana (Lauraceae) , 54270 and 54271. Avo- 
cado. Prom Ecuador. Collected by Mr. Wilson Popenoe, 
Agricultural Explorer. Quoted notes by Mr. Popenoe. 
54270. "(No. 626. Hacienda San Vicente, Ibarra, 
Ecuador.) Cuttings of Avocado No. 47. 'Tamayo.' The 
parent tree stands in one of the 'huertas' of the Ha- 
cienda about* half a mile north of the house at an al- 
titude of 6,100 feet. This variety, so far as can be 
judged by an examination of the parent tree, is either 
a very unusual Mexican, or else a hybrid between the 
Mexican and West Indian races. The fruit is of good 
size, about 18 ounces in weight, and of convenient 
oval form. It is fairly attractive , being smooth, with 
the surface light green, washed or overspread with 
maroon-purple at the stem end. The skin is not woody; 
it resembles both in thickness and texture that of 
such large-fruited Mexican varieties as 'Puebla' and 
'Gottfried.' The flesh is cream-colored with a very 
few, inconspicuous fiber markings. The quality is very 
good. The seed is small, and tight in the cavity. The 
tree appears to bear fair, but not heavy, crops." 
54271. "(No. 628. Ibarra, Ecuador.) Cuttings of 
Avocado No. 49. 'Egas.' The parent tree stands in one 
of the 'huertas' at the Hacienda San Vicente, about 
half a mile north of the house. This is a Mexican avo- 
cado, of much the same general character as 'Puebla, ' 
but having a relatively smaller seed than the latter. 
The fruit is broadly obovoid,8 to 12 ounces in weight 
and glossy maroon-purple when fully ripe. The. skin is 
of average thickness for a large-fruited Mexican avo- 
cado; the flesh is devoid of fiber and is of good qual- 
ity. The seed is tight in the cavity; in some speci- 
mens it is very small, in others, medium-sized. The 
parent tree is a very old one, and is said to be very 
productive."
