oblong-ovate, obtusish, concave, the outer (pag. infer.) subtri- 
quetrous, without longitudinal groove, glabrous, 1% lines long. 
Peduncles axillary, solitary, one flowered, filiform, glabrous, 2-3 
lines long, erect, flower nodding, fruit erect. Calyx 5-parted, 
glabrous; the divisions ovate obtuse. Corolla campanulate, 5- 
parted to the middle; the lobes very obtuse; more than three 
times greater than the calyx, 3 lines and more long. Stamens 
10, the length of the pistil. Filaments a little dilated at the 
base. Anthers two celled, two awned, opening by an apical 
pore. Ovary ovate, glabrous, a little longer than the style, 
rigido superatum. Capsule small, oval, 5-valved; valvlets ob- 
long, obtuse, provided with a longitudinal dorsal sulcus, open-

‘ Habit of 4. ¢e¢ragona, but wholly glabrous. 
Andromeda tetragona difiers from our plant: the leaves 
larger, shorter, pubescent and ciliate (not glabrous), inside (pag. 
super.) more concave, subcarinate, outside (pag. infer.) a little 
convex with a dorsal groove; the branches finally pubescent (not 
glabrous). 
Habitat similar to the following [Axdromeda Stelleriana} 
in alpine places, where they thickly cover the ground. 
CLADOTHAMNUS nov. gen. 155. 
Calyx subgamosepalus, 5-parted, persistent. Petals 5. Cap- 
sule 5 (rarely 6) celled; valves opening on the margin. 
CLADOTHAMNUS PYROLIFLORUS. Tab. I. 155. Shrub saepe 
orygalis, much branched. Branches terete, leafy, the younger 
ones whitish, glabrous. Leaves few, sessile/elliptical or oblong, 
rather attenuate at the base, obtusish with a short cusp, entire, 
glabrous, the inargins of the younger ones ciliate, at length glab- 
rous, glaucescent beneath, veined; veins prominent; an inch or 
an inch and a half long, about 5 lines broad at the middle. Flow- 
ers axillary, solitary. Calyx. persistent, green, scarcely gamo- 
sepalus at base, 5 parted; lobes elliptical, a little unequal, not at
