DRYANDRA LONGIFOLIA. 
(long-leaved DRYANDRA.) 
ORDER. 
MONOGYNIA. 
NATURAL ORDER. 
PROTEACE^. 
Generic Character. — Calyx of four parts or clefts. Stamens four, inserted in the ends of the seg- 
ments, which are hollow (concave). Scales four, situated below the ovai-ium (hypogynous). Ovary 
of two cells, each of which is furnished with one seed. Follicle woody, consisting of two cells, with 
a loose two-parted dissepiment. Receptacle flat. 
Specific Character. — Plant an evergreen greenhouse shruh, growing in some instances to the height of 
six feet, but more frequently from two to four. Leaves decurrent, very long, acute, pinnatifid. at 
the base attenuated and entire, upper side smooth, of a bright pea-green, beneath slightly hairy, 
and of an ash colour. Lobes of the leaves generally of an alternate triangular shape. Flowers of 
an orange brown or yellow. 
The natural order Proteacese^ of which the genus Dryandra presents a distin- 
guished feature, is easily recognised from all other orders in the Jussieuan system, 
first by the hard woody texture of their leaves ; secondly, by their irregular tubular 
calyxes, which in the bud state are valvate in aestivation, by which is meant^ they 
develope or open similar to the opening of valves ; thirdly, by the stamens being 
placed upon the lobes, and the fruit dehiscing, or opening. These remarks are at 
once characteristic of this valuable order, so much prized by every lover of plants 
for the beauty of their foliage, and neatness of their flowers. 
The present coloured representation is a plant of much beauty ; its erect growth, 
lobed and gracefully pendent foliage, render it a valuable acquisition to the green- 
house. These characters, combined with its singular yellow flowers, studding at 
intervals, a stem six feet high, stamp it with an eff'ect at once pleasing and attractive, 
and which recommends it to a place in every collection. 
In Manchester Botanic Garden, from whence we obtained the sample of our 
drawing, the plant flowered profusely in the greenhouse ; it stood full six feet high, 
and being well clothed with verdure, a remarkably pleasing eff'ect was produced by 
the contrasted colour of the flowers and foliage. 
New Holland is its native place, as it is likewise of all the other species in the 
CLASS.
