Coronilla is a pretty genus of some 20 species 
of hardy perennial or shrubby plants^with an oc- 
casional trailer. C. 
varia has naturalized 
in a few places in the 
Atlantic States; its 
juice is poisonous. C. 
emerus is hardy south- 
wards, so also would 
probably be C. juncea 
and C. emeroides. C. 
glaucaand its variega- 
ted form were once 
popular sweet scented 
evergreen tender 
shrubs, and others 
from the south of 
Europe should not be 
ERYTHRINA CRISTA-GALL I. ^ s ; ght Qf where 
pretty low evergreens are desirable. They 
would be especially useful for cemetery purposes in 
California. 
Onolrychis, “saintfoin,” has 70 or 80 species in 
Europe, Asia and Africa. They have mostly pur- 
ple and reddish — sometimes yellow flowers, and 
are best treated as annuals from seed. A few such 
as O. cornuta are evergreen. The British O. sativa 
is not only handsome but an excellent fodder plant. 
Desmodium has no fewer than 155 species from 
North and South America, and the warm parts of 
Asia, Australia and Africa. Thirty-two or three 
forms are native to the United States, quite a num- 
ber of which are northern. The flowers are gener- 
ally in some shade of purple, and sometimes rather 
handsome. They are known, as “tick trefoils.” 
Of the Asiatic shrubby kinds E. tiliaefolium seems 
to be the only one in cultivation at Kew; it is 
Himalayan. D. gyrans is the curious East Indian 
‘‘moving plant.” 
Lespedeza is in 35 species of herbs and shrubs 
from North America (half a dozen in the Atlantic 
States) and also from the temperate and tropical 
parts of Asia. L. bicolor and L. Sieboldi are in 
gardens, often sold as desmodiums. L. Delavayi 
and other Japanese ones are known, and the Hima- 
layan L. criscaspa is evergreen. A few are an- 
nuals. 
Lathyrus has 100 or more species, mostly in 
the northern hemisphere, and in South America. 
It is to this genus that many of the most popular 
flowering peas belong. L. odoratus is the sweet 
pea; L. latifolius the everlasting pea; and there are 
many other very handsome climbers. Some are 
dwarf perennials or annuals, and L. pubescens from 
the Argentine Republic is said to be an evergreen 
shrub with blueish purple flowers Many species 
vary prodigiously, but there does not appear to be 
many hybrids. A dozen or so of species are natives 
and the best are by no means to be despised. L. 
pratensis the English “meadow pea” is yellow flow- 
ered and naturalized at northern points. It is a 
good fodder probably, for cows eat it out whenever 
they can reach it, and will almost climb a thorn 
bush for it! 
Centrosema , Clitoria, etc . , are handsome climb- 
ers called often “Butterfly peas.’’ They are natives 
of North America, Mexico and other parts of the 
world. 
Erythrina has 45 species widely diffused over 
the tropical and warm regions of the world. One 
or two extend to southern parts of the United 
States. Several of the East Indian and South Afri- 
can kinds are naturally arborescent. E. Crista- 
Galli is one of these latter, but becomes semi-her- 
baceous in climates whose seasons are adverse to its 
endurance. If protected around the stool by pine 
needles or saw-dust there is no doubt but it would 
stand as far north as Richmond, Va. 
Butea is a genus of East Indian trees in 2 or 3 
species. I have mentioned but few tropical species, 
but cannot pass over these. 
They have had no sufficient justice done them, 
nor have they been figured except I think by Major 
Beddome in his Flora Sylvatica of South India. 
To my mind B. frondosa is far and away ahead of 
the famed Amherstia. Fancy a tree whose contour 
is that of an apple tree and running in the same 
sizes. In the dry 
season it loses its 
leaves — wholly 
or in part — 
sometime half 
the tree loses 
them and the 
other half retains 
them, when the 
bare half only 
flowers. But the 
whole tree com- 
monly loses its 
leaves as is com- 
mon and then 
about the new 
year the bare branhes arekfiothed with flowers in 
bunches of three or four like a Cercis, as large as 
Erythrina Crista-Galli — and more glowing than 
Clianthus puniceus. Not only are the twigs clothed 
LATHYRUS LATIFOLIUS ALBUS.
