LEPARGYRAEA ARGENTEA. Buffalo berry. Large shrub 

 or small tree with edible red or yellow fruits the size of a currant. 

 These are not considered very palatable raw, but make a very 

 superior jelly. Fruits are gathered when they begin to shrivel by 

 shaking the trees, the berries being caught on sheets. Much resem- 

 bles the so-called Russian olive (Elaeagnus spp.) in foliage. Native 

 of the Missouri River valley and westward. Collected by Dr. David 

 Griffiths.

LEUCAENA GLAUCA. From C. D. Stearns, Pago Pago, Ameri- 

 can Samoa. An unarmed acacialike shrub or small tree, with glob- 

 ular heads of whitish flowers. Propagates readily from cuttings. 

 For this reason and because cattle do not relish the leaves, it is a 

 favorite hedge plant in many countries. However, it is reported 

 that boiled crushed seeds are used for forage in Mauritius. 



41485. LICANIA PLATYPUS. Forest sansapote. From 



Carlos Werckle, Costa Rica. Very large and handsome forest tree, 

 valuable for its timber and its edible fruits. The lumber is said to 

 be considered nearly as valuable as that of cedrela, and the fruits, 

 though smaller, and with less flesh than those of other sansapotes 

 (Licania spp.), are reported to have a very pleasing flavor. 



38807. LIGUSTRUM QUIHOUI. Privet. From F. N. Meyer, 

 Shensi, China. Well-rounded, deciduous, bushy shrub of somewhat 

 diffuse habit, up to 6 feet high, with narrow leaves 1 to 2 inches 

 long, slender downy panicles of fragrant white flowers and masses of 

 purplish or black fruits that contrast with the fine evergreen foliage. 

 Used as stock for Oleafragrans by the Chinese. 



26877. LIGUSTRUM VULGARE. Privet. From F. N. Meyer, 

 Baidari, Crimea, Russia. Reported as a variety seemingly able to 

 stand more drought and heat than the usual forms. Found grow- 

 ing in very dry exposed places. Recommended as of possible value 

 as an ornamental shrub in regions with long, dry summers and fairly 

 mild winters. 



LITCHI CHINENSIS. Litchi. Handsome evergreen tree, about 

 25 feet high, indigenous to South China. Produces in midsummer 

 nearly round reddish fruits, about 1| inches in diameter, with a rough, 

 brittle rind and juicy white flesh of delicious flavor. Important 

 commercial fruit in South China. Fruits are eaten fresh, canned, 

 or dried, in which last form they are called "litchi nuts." (Pis. 

 VI and VII.)
