CHELONEZX. II. Cuetons. SIBTHORPIACEZE. I. Sisrsorria. II. Disanpra. 
Broad-leaved Chelone. Pl. 1 to 2 feet. 
5 C. nemorosa (Dougl. in bot. reg. 1211.) branched, gla- 
brous; leaves ovate, acuminated, serrated : superior ones stem- 
clasping, cordate ; peduncles 3-flowered, downy ; calycine seg- 
ments and bracteas subulate, and are, as well as the corolla, 
rather downy. 4. H. Native of North-west America, in 
mountain woods, near springs and rivulets. Corolla ventricose, 
of a rosy purple colour; anthers woolly. Habit of a species of 
Pentstémon. 
Grove Chelone. Fl. July, Sept. Clt. 1827. Pl. 1 foot. 
Cult. The species of Chelóne are extremely handsome 
border flowers; they grow in any common garden soil, but 
prefer peat, and are readily increased by dividing at the root.

D. Don, in edinb. phil. journ. vol. 19. no. 37. July, 1835.— 
Scrophularínez genera of authors. 
Calyx 4-8-parted, permanent. Corolla rotate, 4-8-cleft, re- 
gular, deciduous, imbricate in estivation. Stamens 4-8, equal, 
alternating with the lobes of the corolla; anthers 2-celled ; cells 
parallel. Style one; stigma capitate, undivided. Capsule 2- 
celled, 2-valved, many-seeded ; placenta large, spongy, globose. 
Seeds erect; testa membranous; albumen copious, dense, 
fleshy. Embryo terete, erect, inclosed. Radicle long, cylindri- 
cal, obtuse, contrary to the umbilicus, centripetal.—Herbs, with 
alternate undivided leaves, and axillary, solitary, pedunculate 
flowers. This small family is intermediate between Scrophula- 
"inece and Primulacee ; and is distinguished from the first by 
the regular symmetrical flowers, and globose placenta; and 
from the last, in the stamens being alternate with the lobes of 
the corolla, not opposite them, and in the 2-celled capsule.

reniform leaves, and axillary, solitary, pedicellate, inconspicuous 
flowers.

on long petioles, reniform, 7-9-lobed ; flowers tetrandrous, some- 
what didynamous. XY.

2 S. Picutncne’nsts (H. B. et Kunth, nov. gen. amer. 2. p.

niform, 7-9-lobed: lobes obtuse; flowers pentandrous. %. F. 
Native on the burning mount of Pichinca, in rugged places 
between the plains of Verdecuchu and Chorro de Cantuna, at 
the altitude of 1800 hexapods. Flowers purple. Seeds very 
minute. Habit of S. Europea. 
Pichincha Sibthorpia. Pl. creeping. 
3 S. nzrU'sa (H. B. et Kunth, |. c. p. 391. t. 177.) plant his- 
pid, creeping ; leaves on long petioles, reniform, many-lobed : 
lobes retuse; flowers pentandrous. %. F. Native of New 
Spain, near Tiangillo, at the altitude of 1500 hexapods. Leaves 
twice or three times the size of those of S. Europea. Flowers 
double the size of those of S. Pichinchénsis, purplish violet. 
Retuse-lobed Sibthorpia. Pl. creeping. 
Cult. Sibthórpia is a genus of singular plants, but of no 
beauty ; they are, therefore, only grown in botanic gardens, or 
those of the curious. "They succeed best in peat soil and moist 
situations, and are readily increased by division. S. Pichinchén- 
sis and S. retusa require protection from frost in winter.
