fats I A japonic A. — Gardening, 
Fatsia has three species, two from Japan and 
one from Northwestern America. F. Japonica has 
two or three variegated and varying forms. These 
are fairly hardy in the Southern States and in the 
south of England. The specimen we illustrate is 
reported to have stood four or five winters at Wash- 
ington, D. C. F. papyrifera is the true rice-paper 
tree, a native of Formosa, and more tender than 
the others, but doing well at southern points, espe- 
cially in Southern California. F. horrida is found 
not only in the Northwest United States, but also 
in Northeast Asia. 
Didymopanax is in two species, one from Japan, 
the other from the Himalayas, and some of the au- 
thorities give a third species from Mexico. 
Helivingia is in two curious and seemingly 
anomalous species from the same regions. The 
flowers are borne on the midribs of the leaves 
(much as in Ruscus), but approximate in structure 
to plants of this tribe. 
Trcvesia is a genus of small and slender trees 
with large, handsome foliage, growing in four spe- 
cies in India and the adjacent islands. The plant 
known as Gastonia in cultivation and having curious 
umbels of yellowish flowers growing from the stems 
below the leaves is T. palmata. It ought to be a 
good sub tropical plant in shady places. 
Elentherococcus is also monotypic, a native of 
China, and hardy in the south of England. 
Heptaplcurum is a more extensive genus of fifty 
— ■ ■ — 
or more species, natives of the Himalayas south- 
wards through tropical Asia, Africa, the Pacific 
Islands and Australasia. H. impressum, from the 
Himalayas, is in European gardens and hardy in the 
south of Plngland. H. venulosum, also East In- 
dian, is sold as aralia digitata. 
PIcdcra has but two species accorded it, one the 
well-known and very variable northern plant, the 
other Australian. There are seventy or eighty 
well-marked forms of H. Helix in cultivation, and 
properly used they are handsome plants indeed. 
The common lorms do well on trees in Central New 
Jersey, and are superb at the South. There used to 
be a splendid specimen of “argenta marginata” ( if I 
remember right) growing on the northwest corner 
of the Smithsonian at Washington, and it is per- 
haps at about that latitude that the finer forms have 
their limit of usefulness. At any rate the Veitch’s 
of Chelsea sent a splendid collection to the Phila- 
delphia Exhibition in 1876, and particular inquiry 
at Fairmount Park last year failed to reveal them. 
Where they do well they should be grown as speci- 
mens, studded over a groundwork of the common 
kind, and supported on rockwork or balloon frames 
of wire. The ordinary forms endure well on walls 
as far north as Yonkers, N. Y., while as trailers on 
the ground, especially under the shelter of larger 
growths, they are good to the Lakes. The “tree 
ivies’’ are shrubby kinds propagated from fruiting 
branches, such as H. Id. chysocarpa. One of the 
ivies appears to have naturalized in Northern Cali- 
fornia. 
Marlea is in four or five species, from tropical 
and sub-tropical Asia and its islands and the cooler 
partsof Australia. M. plantanoides, from Chinaand 
CORNUS MAS VAR1EGATA.* CORNUS FLORIDA, FLORA RUBRA. 
'The flowers oi this species are produced before the leaves.
