Seeds fixed to the central placenta, A small smooth herb, na- 

 tive of North America. Radical leaves 3, entire, linear-lanceo- 

 late, acute. Scape 1 -flowered, length of leaves. This genus 

 is hardly known, but it only appears to differ from Montia in 

 the want of petals. 



1 L. AUTUMNA'LIS (Rafin. 1. c.). Q.B. H. Native of North 

 America, on the banks of the Ohio. 



Autumnal Leptrina. PI. ^ to i foot. 



Cult. The seeds of this plant only require to be sown in the 

 open ground, in a moist situation ; and if the plant is allowed 

 to scatter its seeds, there will be plenty of plants each year. 



XIV. COLOBA'NTHUS (from KoXofios, kolobos, maimed, 

 and avdos, anthos, a flower ; in reference to the want of petals). 

 Presl. in reliq. Haenk. 2. p. 13. t. 49. f. 2. 



LIN. SYST. Tetra-Hexdndria, Telra-Pentagynia. Calyx 4-5- 

 parted. Petals wanting. Stamens 4-6, alternating with the 

 segments of the calyx. Stigmas 4-5. Capsule 4-7-valved, 

 many-seeded. Both Bartling and Kunth insert this genus in the 

 order Caryaphylleae, while the stamens are decidedly perigynous, 

 and therefore ought to come among the Portulacece. 



1 C. ARETIOIDES (Gill. mss. ex Hook, et Arn. in bot. misc. 3. 

 p. 246.) root perennial, with a multiple neck ; calyx 5-parted ; 

 segments ovate; capsule 5-valved. y.. F. Native of Chili, 

 at Los Hornillos, El Paramillo San Isedro, and on the Andes of 

 Mendoza.

 segments lanceolate; capsule 5-valved, O- H. Native about 

 Quito, and on the Cordillera of Chili. Sagina Quitensis, H. B.

LIN. SYST. Pent&nd? M, Trigy'nia. Calyx 5-parted ; lobes 

 oval, permanent, petaloid on the inside and at the margins. Pe- 

 tals wanting. Stamens 5, inserted in the bottom of the calyx, 

 and alternating with its lobes ; anthers 2-celled, inserted by the 

 base. Ovarium surrounded at the base by a 5-lobed fleshy 

 scale. Style wanting. Stigmas 3, crest-formed. Capsule 3- 

 valved, 1-celled. Seeds numerous, fixed to the central placenta. 

 Cape subshrubs. Leaves irregularly verticillate, opposite or 

 alternate, filiform or linear, furnished with scarious stipulas at 

 the base. Peduncles axillary, elongated, bearing umbels of pe- 

 dicellate flowers at the apex ; branches of umbels numerous, 

 divided, many-flowered. This genus differs from Pharnaceum 

 and all the other Caryophyllaceous genera in the stamens being 

 perigynous, and in the leaves being usually alternate ; and from 

 all the genera in the order Paronychiece in the stamens alter- 

 nating with the sepals, not opposite them.

Cult. A mixture of loam, peat, and sand will answer the spe- 

 cies of this genus ; and the pots in which they are grown should 

 be well drained with sherds. The best way of propagating 

 them is by seeds.
