blance to those of the English gorse (Ulex europaeus) . The 
deep green, glabrous , trifoliolate leaves are large and 
similar in shape to those of I well-grown broad beans 
(Vieia faba) . (Adapted from The Gardeners' Chronicle, 
3d ser.> vol. 43, p. 178.) 
Pittosporum erassifolium (Pittosporaceae) , 49474. 
Prom San Francisco , Calif . Seeds presented by Mr. John 
McLaren, superintendent, Golden Gate Park. "An ever- 
green tree introduced from Australia. It is of easy 
culture, not particular as to soil, and is very effec- 
tive as a lawn ornamental, either single or . in groups; 
it also makes a good hedge plant. It is propagated by 
seeds." (John McLaren. ) 
Mr. McLaren has recommended this shrub as one 
which would probably endure the sea breeze and salt 
spray of the Florida coast. 
Strychnos sp. (Loganiaceae ) , 49599. From Kafue, 
Northern Rhodesia. Seeds collected by Dr. H. L. Shantz, 
agricultural explorer. "No. 310. The small-fruited, 
sweet variety which is relished by the natives. It Is 
lemon-orange in color, has a thick stony rind yellow- 
ish brown inside, and is rather juicy with a tart but 
very agreeable flavor. It is unlike any fruit I have 
eaten, is much easier to eat than an orange and, I 
should say, as agreeable to the taste. In eating, the 
seeds are rejected as are those of pomegranates. The 
fruits are borne in great abundance, and apparently 
are possessed of excellent keeping qualities. I think 
this is well worth trying out in cultivation. " (Shantz). 
Letters from Explorers in the Field. 
Mr. Wilson Popenoe , agricultural explorer , writes 
from Guatemala, Guatemala, February, 27, 1920, the fol- 
lowing report on the chayote in Guatemala: 
"While it is true that the chayote (Chayota edulis) 
cannot be likened to the Irish potato in food value, 
yet it occupies a position in the dietary of the Gua- 
temalan Indians somewhat analogous to that occupied by 
the potato inmany northern countries. This analogy is 
evidenced by the abundance in which the chayote is seen 
on Guatemalan markets in the fall and winter months ; 
no other vegetable Is so conspicuous and no other is 
sold in such quantities. 
"The Cultivation of the plant is not limited to 
any particular zone in Guatemala, but is more extensive
