Cult. Cherleria is a genus of very pretty alpine plants, 
having the appearance of some species of Arendria. They 
should be grown in small pots, well drained with potsherds, in 
a mixture of sand, loam, and peat, and placed among other 
alpine plants. They are increased by dividing the plants at the 
root, or sometimes by seed.

astrum, an affixed signification, like.) Michx. fl. bor. amer. 1. p. 
275. D. C. prod. 1. p. 421. Micropétalum, Pers. ench. 1. 
p. 509. 
Lin. syst. Decéndria, Tri-Tetragynia. Calyx 5-sepalled. 
Petals 5, very minute, entire or wanting. Stamens 10, perigy- 
nous. Stigmas 4, sessile, ligulately-setaceous. Capsules ovate, 
longer than the calyx of 4-valves.—North American herbs, with 
the habit of Stellaria or Spérgula. This genus ought more 
properly to have been placed in Paronychiew, from the perigy- 
nous insertion of the stamens. 
1 S. tanucindsum (Michx. fl. bor. amer. 1. p. 275.) plant 
densely pubescent ; leaves lanceolate, tapering into the foot- . 
stalk ; peduncles almost solitary, long, at length reflexed ; flowers 
apetalous. 2. H. Native of North America on the mountains 
of Virginia and Carolina. Micropétalum lanugindsum, Pers. 
ench. 1. p. 509. Stems densely clothed with very fine wool. . 
Woolly Spergulastrum. Fl. June, July. Clt. 1821. Pl. 3 ft: 
2 S. Lanceoxa'tum (Mich. fl. bor. amer. 1. p. 275.) plant

panicled; petals ovate, very short. 2. H. Native of North 
America on moist rocks from Canada to Carolina. Micro- 
pétalum lanceolatum, Pers. ench. 1. p. 509. Spérgula borealis,

very smooth; leaves linear, erect ; panicle loose ; petals lanceo- 
late, length of sepals. Yy.H. Native of North America near 
springs and on shady rocks, from New York to Virginia, Canada, 
&c. Spérgula longifdlia, Hook. fl. bor. amer. p. 86. Spérgula 
gramínea, Bigel. 1. c. Like Stellaria graminea. 
Grassy Spergulastrum. Fl. June, July. Pl. 4 foot. , 
Cult. A genus of weed-looking plants, not worth culti- 
vating except in general collections. ‘They should be grown in 
pots in a mixture of peat and sand. They may be either in- 
creased by dividing the plants at the roots or by seed. 
XXXVIII.? HYDROPITYON (from vdwp, hydor, water, 
and mrve, pitys, a pine-tree or fir; water plants resembling the 
pine tree in the fine whorled leaves.) Geert. fruct. 3, p. 19. t 
183. f. 2. D. C. prod. 1. p. 422. 
Lin. syst. Decándria, Monogynia. Calyx of 5 sepals. Pe- 
tals 5,ovate-roundish. Stamens 10; filaments thick and pilose ; 
anthers cordate. Ovary oblong. Style 1. Stigma orbicular. 
Capsule I-seeded. Seed naked.—East Indian water herbs, 
with whorled pinnate leaves, and small axillary flowers. This 
genus most probably ought to be removed from this order. . 
1 H. Zeyza’nicum (Gert. l. c.) leaves pinnate, in whorls; 
stems arched ; flowers axillary, sessile. 22S. W. Native of 
the East Indies. Flowers red. 
Ceylon Water-fir. Pl. floating. .

whorls, pinnate; stems straight; flowers axillary on long pe- 
duncles. 2%? S. W. Native of the East Indies'and Malabar. 
H. calycinum, Gert. Hottdnia I’ndica, Lin. spec. 208.—Burm. 
zeyl. p. 121. t. 55.—Rheed. hort. mal. 12. p. 71. t. 36. Petals 4, 
greenish-red. The whole plant has a somewhat grateful odour. 
The flowers mixed with ginger and cardamon in milk-whey are 
used in Malabar as an anti-dysenterical medicine. 
Stalked-flowered Water-fir. Pl. 4 foot. 
Cult. As neither of the species of Hydropítyon has ever 
been introduced into Europe in a living state, it is difficult to 
say what mode of cultivation they require. We think from the 
nature of the plant that it will be impossible ever to cultivate 1t 
in this country.
