Cult. Cherleria is a genus of very pretty alpine plants, 

 having the appearance of some species of Arenaria. 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. 



XXXVII. SPERGULA'STRUM (from spergula, spurry, and 

 astrum, an affixed signification, like.) Michx. fl. bor. amer. 1. p. 

 275. D. C. prod. 1. p. 421. Micropetalum, Pers. ench. 1. 

 p. 509. 



LIN. SVST. Decdndria, Tri-Telragynia. Calyx 5-sepallecl. 

 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 Spergula. This genus ought more 

 properly to have been placed in Paronychiece, from the perigy- 

 nous insertion of the stamens.

 densely pubescent ; leaves lanceolate, tapering into the foot- 

 stalk ; peduncles almost solitary, long, at length reflexed ; flowers 

 apetalous. I/. . H. Native of North America on the mountains 

 of Virginia and Carolina. Micropetalum lanuginosum, Pers. 

 ench. 1. p. 509. Stems densely clothed with very fine wool.

 late, length of sepals. 3 . H. Native of North America near 

 springs and on shady rocks, from New York to Virginia, Canada, 

 &c. Spergula longifolia, Hook. fl. bor. amer. p. 86. Spergula 

 graminea, Bigel. 1. c. Like Stellaria graminea. 



Grassy Spergulastrum. Fl. June, July. PL |- 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.? HYDROPI'TYON (from vtup, hydor, water, 

 and TTirvf, pitys, a pine-tree or fir ; water plants resembling the 

 pine tree in the fine whorled leaves.) Gsert. fruct. 3. p. 19. t. 

 183. f. 2. D. C. prod. 1. p. 422. 



LIN. SYST. Decdndria, 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 1 -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. ZEYLA'NICUM (Gaert. 1. c.) leaves pinnate, in whorls ; 

 stems arched ; flowers axillary, sessile. I/. ? S. W. Native of 

 the East Indies. Flowers red.

 whorls, pinnate ; stems straight ; flowers axillary on long pe- 

 duncles. H ? S. W. Native of the East Indies and Malabar. 

 H. calycinum, Gaert. Hottonia 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-fiowered Water-fir. PL foot. 



Cult. As neither of the species of Hydropityon 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 it 

 in this country.

 plant without beauty). Benth. mss. in Lin. soc. herb.
