Cult. The hardy shrubby kinds of this genus are amongst 
the most beautiful little shrubs for ornamenting rock-work. The 
frame and green-house kinds should be planted in pots in a mix- 
ture of sand, loam, and peat, so that they may be protected during 
winter by a frame; the smaller kinds of these may be planted 
out on rock-work during the summer months. -Ripened cuttings 
will strike root freely, if planted under a common hand-glass in 
a sheltered situation, in August or September; or they may be 
raised by seeds, which ripen in abundance. The perennial

and biennial herbaceous kinds should be grown in pots, (so 
that they may be protected by a frame during winter), in a 
mixture of sand, loam, and peat; they are easily increased by 
seeds. The annual kinds are all beautiful plants, and the seed 
requires to be sown in the open border : they prefer a light rich 
soil, All the species of Helianthemum deserve to be cultivated in 
every collection on account of the elegance and various hues of 
their blossoms.

mens in length. Stigma simple. Capsule 1-celled, 3-valved, 
1-3-seeded, oblong or obovate, coriaceous, smooth or pubescent.

pubescent ; stems suffruticose, 
erect; branches elongated ; leaves 
filiform, awl-shaped, rather imbri- 
cated; peduncles solitary, rising 
laterally from the leafy bud ; calyx 
cylindrical, obtuse; capsules pu- 
bescent, always l-seeded; valves

Willd. hort. berl. t. 15. Sweet, 
cist. t. 36. Leaves permanent. 
Stamens about 15. Peduncles 5 or 
8 lines long. According to Nuttal, 
this plant, which is a native of New 
Jersey, has aggregate instead of 
solitary peduncles ; therefore his 
plant may be a distinct species. 
Flowers yellow (f. 61.).

2 H. Nurra’tun (Sweet, cist. p. 19.) equally pubescent ;

rather imbricate, but distinct from the stem; pedicels lateral, 
crowded, when in fruit from 5 to 8 lines long ; calyx cylindrical,
