branches terminating i in drooping panicles. The stems are gla 
below and pubescent above, becoming somewhat tawny- ee 
' tomentose in the inflorescence. The opposite leaves are green and 
nearly glabrous above, and Suds with a grayish-white tomentum 
n the under surfaces. They are two to six inches long, ovate- 
lanceolate or lanceolate, acute or acuminate, and have toothed 
margins. 
ish Leas Many cl preh of several flowers on short tomentose 
pedicels make up the curving panicles, which are three to seven 
inches long. ‘The small pubescent rere) has stag ate lobes. The 
corolla i is one half to three quarters of an inch long, the tube cylin- 
c, the four spreading lobes rounded. ‘The four short stamens are 
attached slightly above the middle of the corolla tube. ‘The short 
style is tipped with an ovate stigma. The two-celled capsule is 
less ies an inch long. 
The summer lilac, or butterfly bush, is one of the shrubs requiring 
some protection if cultivated very far north, but in our climate is prac- 
tically hardy. Although killed back to the ground during a severe 
winter, it recovers strongly the next spring, and sends up new shoots 
which flower the same season. Plants in the New York Botanical 
Garden hold the green wood until the first of February of an average 
winter. Its wide-branching habit, the grace of its panicles of lilac 
flowers with deep yellow eyes, its delicate fragrance, and the white- 
ness of the under side of its leaves, make it a very valuable shrub 
for late summer and early autumn. The varieties Veitchiana and 
magnifica are even more attractive. 
The genus Buddieia is quite extensive from Texas throughout 
tropical America, and in China and Japan, but is represented in cul- 
tivation by only a few species. B. Colville, B. officinalis and B. 
astatica are not hardy, but are grown under glass. The last is a 
white-flowered kind which is grown as a winter cut flower and is
