a EF, floribinda H. B. et Kunth is a native of New Granada, on the Andes, 
with white flowers, and shining leaves, which are clammy when young. The 
plant of this name, in the British gardens, appears to be only a variety of the 
preceding species. 
a E. resindsa Pers., Stereédxylon resindsum Ruiz et Pav., is a glabrous 
shrub, a native of Peru, on the cold parts of hills. A plant of this species has 
stood against a south wall, in the Kew Gardens, since 1832. 
# FE. pulverulénta Pers., Steredxylon pulveruléntum Ruiz et Pav., is a 
shrub, hairy in every part, with white flowers ; growing to the height of 8 ft. or 
10 ft. It is anative of Chili; and plants of it have been in the Horticultural 
Society’s Garden since 1831. 
Twenty other species ave described in Don’s Miller., iii, p. 193. to p. 195., all 
natives of South America, and probably as hardy as those above mentioned ; 
but it does not appear that any of them have been introduced. 1 

CHAP. LVII. 
OF THE HARDY AND HALF-HARDY LIGNEOUS PLANTS OF THE 
ORDER SAXIFRA‘GEX, TRIBE HYDRA’NGEA. 
Tue only woody plants contained in this order are included in the tribe 
Hydrangez, which contains the well-known green-house, or rather cold- 
frame, plant, Hydrangea Horténsia, that may be considered as half-hardy ; and 
some species, natives of North America, which are quite hardy. There are 
also some half-hardy species, natives of Asia. They are all easily propagated 
by cuttings, and will grow freely in any soil that is rather moist.

Identification. Lin. Gen., 557.; Dec. Prod., 4. p. 13.; Don’s Mill, 3. p. 232, 
Synonymes. Wydrangea, and Horténsza Juss. 
Derivation. From hudér, water, and aggos, a vessel; with reference to some of the species which 
grow in water; or, as some suppose, from the capsule resembling a cup. 
Gen. Char. Flowers generally deformed; but some of them hermaphro- 
dite and fertile. Tube of calyw hemispherical, 10-ribbed, rather trun- 
cate, adnate to the ovarium; limb: permanent, 5-toothed. Petals 5, 
regular. Stamens 10. Styles 2, distinct. Capsule 2-celled, with intro- 
flexed valves, crowned by the teeth of the calyx and styles, flattish at the 
top, opening by a hole between the styles. Seeds numerous, reticulated. 
(Don’s Miill., iii. p.232.)—Shrubs, with opposite leaves. Flowers corym- 
bose, pink, or yellowish white; the marginal ones sterile, and large, in con- 
sequence of the teeth of the calyx being dilated into broad, petal-like- 
coloured segments; the rest of the sterile flower having the other parts 
partially abortive.
