Dovy ciiiuin is in six species from Mediterranean 
regions. They are tender evergreen sub-shrubby

perennials in Britain, with red, white or red and 
white flowers. D. suffruticosiim is perhaps as hardy 
as any of the evergreens. The herbaceous ones 
stand more cold. 
Lotus has from 50 to 100 described species (?) 
from Europe, Asia, Africa, America and Australia. 
They are mostly from the warmer regions, but sev- 
eral pass northwards, L. corniculatus and its varie- 
ties being well known. L. Porto-sanctanus is said 
to be a small evergreen shrub; I don’t know it, but 
L. peliorhynchus, with scarlet flowers, has recently 
been advertised and not very long ago introduced 
from leneriffe. L. Jacobasus comes as near to a 
black flower (sometimes) as anything known, and 
there are other small, tender evergreens perhaps 
useful as bedders. 
Aniorpha has eight species of shrubby or sub- 
shrubby plants, all from North America and with 
pretty purple or blueish flowers. 
Indigofer a is a large genus of 270 species, dif- 
fused over all the warm regions of the world. They 
are annual or perennial herbs or evergreen shrubs. 
often quite handsome. Among the latter I. decora 
and vars. is from China and Japan and I. Gerardiana 
(Dosua) from the Himalayas. These are hardy 
enough to live as herbaceous plants northwards. It 
is likely that such as pulchella, atro-purpurea, spi- 
nosa. etc., might also prove useful southwards. 
The four native species are from the Gulf states and 
are hairy herbs or sub-shrubs with loose panicles of 
pink or purple flowers. The indigo plant has natu- 
ralized south also, and was once largely cultivated 
there. 
Galega has but three species. They are tall 
herbs from Central Europe and Western Asia, with 
puiple, blue, and white flowers. 
Wistaria is in two or three species and a num- 
ber of varieties, some of them double flowered. 
They are natives of Eastern Asia and the Southern 
United States. Both the Asiatic and native spe- 
cies have white forms, and all are well-known, hand- 
some climbers . 
roraia in close affinity is 
from China. 
monotypic genus 
Robinia, ‘Locusts,” have five or six species from 
North America and Mexico. A large number of 
varieties have been selected in European gardens 
with pink and yellowish flowers and with odd habits 
of growth, such as vars. fastigiata, inermis, mono- 
phylla, tortuosa, etc. R. hispida and R. viscosa 
make handsome objects either as shrubs or grafted 
as low standards. Both are hardy to the lower lakes 
at least. 
Colntea has three or more species from Europe 
and Asia. C. arborescens is extremely hardy and 
makes a small tree under favorable conditions. 
AVISTARIA CHINENSIS ALBA. (Standard.) 
Haliiiiodendron argenteiim is monotypic and 
from Central Asia. It is grafted standard high upon 
the laburnum in English nurseries, and with it
