( Contmiicd. ) 
Ligustrum “Privet” is in 25 species and a num- 
ber of varieties in Europe, temperate and tropical 
Asia and Australia. L. vulgare is naturalized in 
the Delaware valley and other places at the north. 
L. ovalifolium has supplanted it as a hedge plant, 
and is also a good sub-evergreen summer flowering 
shrub, but not so hardy. 
There are several other useful deciduous species 
for the north and evergreens for the south, some of 
which are prettily variegated. 
Amsonia, in 4 species, are natives of North 
America and Japan. They are herbs with cymes of 
blue flowers. 
Taberncsmontana is a large genus of 150 species, 
many of which are good sized trees and shrubs. 
They are found throughout the tropics. T. coronaria 
fl. pi. does well in southern California, and some 
others are being tried in South Florida. They are 
often handsome fragrant shrubs with white or 
creamy flowers. 
Neriiun “oleander” has 2 or 3 species in Medi- 
terranean countries, sub-tropical Asia and Japan. 
There are many varieties, and, although often 
unsuspected, their juices are venemous poisons. 
Apocynum, “flytrap,” “Indian hemp,” etc., is 
in 5 species, natives of the south of Europe, North 
America and temperate Asia.

Trachelospermuin Jasminoides aL the Lower South. 
permum” by Lindley, has six or seven species in 
the East Indies, the Malay Islands, Eastern Asia 
-and North America. T. jasminoides and its varie- 
ies are well known fragrant white flowered climbers

hardy in the lower south. T. difforme, the native 
species, is found from the middle Delaware valley 
southward. It has herbaceous stems, inconspicuous 
flowers, and is of little use unless perhaps for 
hybridizing experiments. 
Beainnontia, in 4 species, are handsome East 
Indian and Malayan climbers v/ith fine white flow- 
ers, but somehow they are rarely seen in cultiva- 
tion, although I imagine they might succeed in the 
warmest parts of the south. 
Adeniiiin, in 4 species, may pass with a similar 
remark, but are very di fferent plants. x\. obesum, 
sometimes seen in gardens in the Eastern tropics, 
is a native of Aden and other parts of iVrabia. It 
is like a huge leafless sugar beet, with a thumb- 
like branch or two at the top, tipped off with a few 
leaves and a little bunch of pink oleander like 
flowers. I think it might succeed somewhere about 
the Gila valley. 
Dipladenia in 40 species, natives of tropic. 1 
America, are often superb climbers, but our south- 
ern friends do not seem to have given them much 
attention. • There is no good reason why they 
should not succeed as summer climbers, or even 
permanently in the parts of Florida where Echites, 
Andrewsei and Vallaris dischotoma succeed. 
Mandevilla has 30 species, but the deliciously 
fragrant white flowered M. suaveoleus is the only one 
cultivated. Several are quite small flowered, and 
others are confused with Echites, I fancy. I don’t 
know about the ability of M. suaveoleus to stand
