CLASS I PLANTS WITH TWO COTYLEDONS (DICOTYLEDONEiE). 
THE ROSE TRIBE (rOSACE^). 
Crataegus tanacetifolia. Tansy-leaved Hawthorn. A fine species of 
hawthorn, known from Crataegus odoratissima and orientalis by its yellow 
solitary sessile fruit, to which a small number of leafy bracts adhere irregularly ; 
but also by its regularly pinnatifid leaves, the fine toothings of which are all tipped 
with a gland. Like those species, this is hardy and very handsome ; it is 
multiplied by grafting on the common hedge hawthorn. jBot. Reg.-, 1884. 
Crataegus odoratissima. Sweet-scented Hawthorn. This species forms a 
common bush on the hills adjoining the Black Sea, and elsewhere in the Crimea. 
It is described by Bieberstein as growing to the size of the common hawthorn ; in 
this country when grafted upon that species it acquires a dense round-headed habit, 
which diminishes its beauty in some degree ; this is, however, compensated by its 
multitude of deliciously perfumed flowers, and the rich clusters of red fruit with 
which it is loaded in the autumn. Bot. Reg.., 1885. 
THE primrose TRIBE (PRIMUL ACEJE.) 
Douglasia NIVALIS. Snow-Douglasia. This elegant little plant was dis- 
covered by Mr. Douglas, when crossing the Rocky Mountains in April 1827, in 
latitude 52 degrees north, and longitude 118 degrees west; at an estimated 
elevation of 12,000 feet above the level of the sea. The plant forms a thick tuft, 
consisting of numerous perennial branched stems ; which are round, of a bright 
purplish brown, covered with rigid branched hairs. Leaves are opposite, linear, 
glaucous green, covered with hairs. Flowers proceeding from the axils of the upper 
leaves, from three to six on each little branch ; at first sessile, but the footstalks 
lengthen by degrees until the fruit is ripe, when they are three quarters or a full 
inch in length, also covered with hairs. The corolla is of a vivid purple, funnel-
