success appears to be In the continuous layering of the 
shoots. As soon as the young growths are an inch or so 
long, the previous summer's branches are weighed down to 
the ground by placing stones on them. A little soil may 
come between. By this system the whole plant is always 
renewing its root system at the younger parts. At Glasne- 
vin I have seen a patch 8 feet across, in the rudest 
health. This system is, no doubt, helped by the moist, 
equable climate of Dublin. As this shrub is found on cal- 
careous rock, stones of the same character would appear to 
be preferable for layering, but Sir P. Moore tells me he 
does not consider this Daphne needs lime. He recommends 
good loam or peat and leaf -soil and partial shade ." (Abridg-

Euonymus spp. (Celastraceae. )40696-698. Seeds of spin- 
dle woods from Kansu, China. Three species, one forming 
heavy trunks when allowed to grow unmolested, another low- 
growing, and the third of very small, creeping growth, 
found on shady places amongst scrub and moss, at altitudes 
of between 7000 and 8000 feet." (Meyer's introductions and

Gentiana lutea L. (Gentianaceae . )40670. Plants of the 
yellow gentian from Ploraire, near Geneva, Switzerland. 
Presented by Mr. H. Correvon. "A tall, stout, hollow- 
stemmed perennial herb of open or partly open grassy places 
on the mountains of southern and central Europe. Its 
large flowers are bright-yellow and spotted, and occur in 
axillary clusters. The underground portion is frequently 
a yard in length, and may have several long branches. It 
is commonly collected in flower. To prevent its extermi- 
nation the Austrian government imposed a heavy fine for 
collecting a root not at least 2 cm. (nearly an inch) In 
diameter at the top, this ordinarily requiring a three 
years' growth and insuring Its previous propagation by 
seed. The United States supply comes chiefly from Eu- 
rope. "(The National Standard Dispensatory.) 
Hippophae salicifolia D.Don. (Elaeagnaceae .) 40715 . Seeds 
of a sea-buckthorn from near Pao dji, Kansu, China. "A 
species of sea-buckthorn, reaching a height of 40 feet, 
with a trunk 2 feet in diameter; leaves larger than in 
E. rhamnoides ; berries of pale waxy color, very sour. Oc- 
curring in mountain ravines and on pebbly creek bottoms, 
sometimes to the exclusion of almost everything else. Of 
value as an ornamental park tree, suited especially for
