must be taken not to water it too copiously. The old roots of this species, like those of many of its allies after a time 
lose their vitality, and, by their continued increase, become a nidus of support to the succeeding younsr roots - but i 
cultivation it is advisable occasionally to turn the plant out of the pot & ^ b > "ut in 
and divest it entirely of the old roots, at the same time cutting away 
the lower part of the caudex, which will also be found to be dead. The 
plant on being repotted will soon emit young roots, and show a more 
vigorous growth. It is increased by offsets, and our plant shows at 
this time the appearance of producing perfect seeds.— ^of.^a^.^t 4591. 
354. Spiraea. Doxjglasii. Ho 
A very fine hardy 
shrub, with deep rose-coloured flowers. Native of Oregon, 
Belongs to Eoseworts. (Fig. 178,) 
This brilliant addition to our Shrubberies is one of the hardiest of 
the North American Flora, naturally growing as far to the Northward 
as the straits of St. Juan de Fuca. Douglas found it on the plains 
of Oregon. In general appearance it resembles tlie J^pircBa tomentosa 
of the United States, from which it differs in the following particulars : 
It grows as well, if not better, in common garden soil as in peat It is 
twice as robust a plant. Its leaves are longer, narrower, serrated 
not crenate, and white not brown underneath. The flowers are a 
deeper rose colour, and therefore handsomer, and form a larger and 
closer panicle, which always terminates in a round extremity, and is 
not taper-pointed. Moreover the carpels are perfectly smooth, and 
not buried in long down. It is one of the best shrubs in the Garden 
of the Horticultural Society, where our drawing was made in July. 
355. Acacia guandis. Ilenfrey. A 
!New Holland shrub, of the Leguminous 
Order, from the Swan Eiver Colony. <^ 
Flowers in yellow balls, in the spring. 
This seems to be in no respect different from 
Mr. Bentham's ^. lasiocarpa, published years ago, 
as far as can be ascertained from the materials 
laid before the public. It may be described in 
popular terms as a good variety of A. pukhdlof 
with larger and more copious balls of flowers. 
356. Epidendrum coriifolium. Zind- 
Uy. A greenhouse epiphyte, nati\e of 
Central xVmerica. Flowers green. Intro- 
duced by the Horticultural Society. 
This singular plant is, in all its parts, of a tough, 
thick, leathery texture, and is generally glazed, 
as it were, with a shining exudation. The narrow 
stiff leaves are blunt, about six inches long.
