written on the diseases of wheat, and the effects of light upon 
plants, &c.). D. C. prod. 4. p. 574, 
Lin. syst. Tetrdndria, Monogy’nia. Calyx with an ovate 
tube, and a 4-lobed limb; lobes nearly equal, without any acces- 
sory ones. Corolla funnel-shaped, with a glabrous throat, and a 
4-lobed limb. Stamens hardly exserted. Stigma 2-lobed. Cap- 
sule 2-celled, 2-valved, with an entire oval deciduous dis- 
sepiment ; valves concave, crowned by the teeth of the calyx, 
falling asunder from being cut vertically along the dis- 
sepiment. Seeds solitary in the cells, fixed to the middle 
dissepiment.—American herbs, clothed in every part, except the 
corollas, with tomentum or wool. Leaves opposite, sessile, 
lined by the nerves. Stipulas cleft into many bristles. Flowers 
axillary, sessile, few, verticillate, bracteolate-—This genus is 
nearly allied to Staélia from the structure of the fruit, but to 
Borréria or Diddia from habit.

rolla funnel-shaped, with a terete tube, and a 5-7-lobed limb; 
lobes oblong. Stamens 5-7, exserted from the throat, but 
shorter than the corolline lobes. Style filiform, thickened at the 
apex; stigma 2-lobed. Fruit egg-shaped, almost naked at the

CXCVIII. Gairtonra. CXCIX. Macnaonta, 
apex, containing 2 separable, 1-seeded, indehiscent nuts, — 
Hard, oppositely-branched herbs, velvety from fine down in every 
part, as also on the corollas. Leaves linear, ending in a cal- 
lous mucrone, opposite, bearing twin stipulas on both sides, 
which are sometimes short and truly stipula-formed, and some- 
times long and foliaceous, and in the latter case appearing like 
those of Galium. Flowers some in the forks of the branches, 
sessile, solitary, and naked, and others sessile at the tops of the 
branches, between the 2 superior leaves.—Habit of Aspérula, 
with a velvety aspect. This genus ought probably to be placed 
among Rubiaceae, sect. Stellate. 
1 G. Onve'rm (Rich. 1. c.) stem multiple, brachiate, and as 
if it was articulated; branches opposite; leaves distinct at the 
base, linear-subulate, spinescent at the apex; stipulas leaf- 
formed, distinct from the leaves. h.? %.? F. Native of 
Persia, between Teheran and Ispahan, where it was collected by

3 G. Szowírzi (D. C. prod. 4, p. 574.) stem branched at | 
top; branches erect: leaves subulate ; upper ones connate at the 
base, and adhering to the stipulas, and therefore appearing tri- 
furcate and trispinose at the apex. 2%. F. Native of Persia, 
in very arid, stony places near Nekhitcheven, where it was col- 
lected by Szowitz.— A very distinct species.

Cult. The species of Gaillénia should be grown in pots, half 
filled with pot-sherds, in a mixture of sand and peat, and placed 
among other alpine plants. They may be increased either by 
cuttings or seeds.
