Gen. Char. Calyx (fig. 1.) inferior, of 1 sepal, flat, perma- 
nent, in 4 or 5 deep, spear-shaped segments. Corolla (see fig. 2.) 
of 1 petal, wheel-shaped ; limb nearly flat, in 4 or 5 deep spear- 
shaped segments, larger than the calyx. Nectaries (see fig. 3, a.) 
8 or 10, consisting of two small depressions, in the base of each 
segment of the corolla, on the upper side, encompassed with short 
upright bristles. Filaments (see fig. 2.) 4 or 5, awl-shaped, flat- 
tened, smooth, dilated at the base, rather spreading, shorter than 
the corolla. Anthers heart-shaped, deflexed, bursting lengthwise. 
Germen (see fig. 4.) superior, egg-oblong, cloven at the summit. 
Styles (see fig. 4.) 2, very short, distant. Stigmas blunt. Capsule 
(see fig. 5.) egg-shaped, pointed at each end, of 2 valves, and 
1 cell. Seeds (see figs. 6& 7.) numerous, small, roundish, com- 
pressed, bordered, attached to the edges of the valves only. 
The 4- or 5-parted calyx ; the wheel-shaped corolla with 2 
nectariferous glands at the base of each segment ; and the 1 -celled, 
2-valved capsule ; will distinguish this from other genera, with an 
inferior, monopetalous corolla, in the same class and order. 
One species British. 
SWE'RTIA PERENNIS. Perennial Swertia. Marsh Felwort. 
Marsh Gentian. Spotted Gentian. 
Spec. Char. Plant smooth. Stems upright, and as well as 
the peduncles 4-sided. Leaves almost all radical, egg-shaped or 
elliptic, nerved. Racemes panicled, terminal. Segments of the 
corolla 5, spear-shaped, pointed.

Localities. — In watery alpine meadows. — Hudson records it as having been 
found wild in Wales by Dr. Richardson, but some mistake is to be suspected, as 
no person has found it since ; and, as Sir J. E. Smith observes, so fine a plant 
could scarcely be overlooked.
