a kind of whorl. I/ . G. Native of Mexico. Flowers purplish 

 inside. 



Purplish Cerdia. PI. pr. 



Cult. These plants will grow well in a mixture of loam and 

 sand, and are easily increased by dividing at the root, by cut- 

 tings, or by seeds. 



Tribe IV. 



POLLICHIE'^E (this tribe only contains the genus Pollichia'). 

 D. C. prod. 3. p. 377. Calyx 5-toothed ; tube urceolate. Sta- 

 mens 1-2, inserted in the throat of the calyx. Petals wanting. 

 Stigma bifid. Fruit or utriculus valveless, 1-seeded. Bracteas 

 and calyx becoming large and fleshy after flowering, and forming 

 something like a berry. Suffruticose herbs, with opposite, sub- 

 verticillate stipulaceous leaves.

 M.D., author of a History of the native plants of the Pala- 

 tinate of the Rhine). Sol. in Ait. hort. kew. (1789) 1. p. 5. ; 

 3. p. 505. Juss. mem. mus. 2. p. 388. but not of Med. nor 

 Roth, nor Willd. Neckeria, Gmel. syst. (1796) 1. p. 16. but 

 not of Hedw. nor Scop. Meerburgia, Mcench, suppl. (1802) 

 p. 116. 



LIN. SYST. Mondndria, Monogynia. Calyx campanulately 

 urceolate, 5-toothed, permanent. Petals wanting, unless the 

 scales at the throat are to be taken for them. Stamen 1 (ex 

 Moench. rarely 2) inserted in the throat of the calyx. Style 

 filiform ; stigma bifid. Capsule valveless, 1-seeded, inclosed 

 in the thickened tube of the calyx. A suflfruticose branched herb. 

 Leaves linear, opposite, but at first sight appear verticillate, in 

 consequence of 2 rameal leaves rising in each axil, furnished 

 with scarious acute stipulas. Flowers small, aggregate, sessile, 

 bracteate. 



1 P. CAMPE'STRIS (Ait. I.e. Smith, spicil. 1. t. 1.). Tj .? 7;.? 

 F. Native of the Cape of Good Hope. Neckeria campestris, 

 Gmel. 1. c. Meerburgia glomerata, Mcench. 1. c. Flowers 

 greenish. Bracteas mixed with the flowers, ciliated ; scales full 

 of sweet juice. 



Field Pollichia. Fl. Sept. Clt. 1780. PI. i foot. 



Cult. The seeds of Pollichia must be raised on a hot-bed ; 

 and when the plants are 2 inches high, they may be planted out 

 singly into pots, placed among the greenhouse plants, and after- 

 wards treated like them. 



t Genera placed in Paronychiece, but are not sufficiently known. 



XVIII. LITHO'PHILA (from \idoc, lithos, a stone, and 

 4><\o>, phileo, to love ; this plant delights to grow among stones). 

 Swartz, fl. ind. occ. 1. p. 47. t. 1. D. C. prod. 3. p. 380. 



LIN. SYST. Diandria, Monogynia. Calyx profoundly 3- 

 parted, acute. Petals 3, ovate-lanceolate. Scales, nectaries, 

 or abortive stamens 2, opposite the segments of the calyx. 

 Stamens 2, at one side of the ovarium. Style thick, bluntly 

 emarginate at the apex. Fruit unknown. A very minute gla- 

 brous herb. Leaves stem-clasping, linear, obtuse. Flowers 

 white, crowded. 



1 L. MUSCO!DES (Swartz, 1. c. p. 48.). Native of the desert 

 island of Navaza, among rocks. 



Moss-like Lithophila. PI. 1 inch. 



Cult. This plant is not worth cultivating, unless in botanic 

 gardens. Should it ever be introduced to our gardens, we would 

 recommend its being grown in a pot filled with broken stones, 

 having the crevices filled with vegetable mould. It may pro- 

 bably be propagated by seeds. 



XIX. SELLOWIA (in honour of Frederick Sello, a Ger- 

 man botanist, who was lately drowned in some creek of the 



Amazon ; and who has sent home many fine collections of Bra- 

 silian plants). Roth. nov. spec. p. 162. D. C. prod. 3. p. 380. 



LIN. SYST. Pentdndria, Monogynia. Calyx urceolate, 5- 

 cleft, membranous, 10-ribbed ; lobes short, lanceolate ; ribs 

 bearing alternately a petal and a stamen. Petals 5, oval, altern- 

 ating with the calycine lobes. Stamens 5, fixed in the middle 

 of the calycine lobes, and shorter than them ; anthers didy- 

 rnous. Style 1 ; stigma obtuse. Capsule 3-valved, 1 -celled, 

 1-seeded. A quite glabrous herb, with the habit of Illecebrum 

 verlicillatum. Leaves opposite, oblong-oval. Flowers 1-2 in 

 the axils of the leaves, small, white, and somewhat pedicellate. 

 It is not known whether the leaves are stipulaceous or naked. 



1 S. ULioiNbsA (Roth. 1. c. p. 163.). Native of the East 

 Indies, in bogs. 



Bog Sellowia. PI. proc. 



Cult. Place a pan of water under the pot in which this plant 

 is grown. 



ORDER CXII. SCLERA'NTHE^ (plants agreeing in im- 

 portant characters with Scler&nthus). Link. enum. p. 417. 

 Bartl. ex Mart, nmarant, p. 67. Paryonychiese, Tribe V. Scle- 

 ranthese, D. C. prod. 3. p. 377, &c. 



Flowers hermaphrodite. Calyx 4-5-parted(f. 24. a.). Stamens 

 from 1 to 10, inserted in the orifice of the tube (f. 24. a.). Ova- 

 rium simple, 1-seeded. Styles 2 (f. 24. e.) or 1, emarginate at the 

 apex. Fruit a membranous utricle, inclosed within a hardened 

 calyx. Seed hanging from the apex of a funicle, which arises 

 from the bottom of the cell. Embryo cylindrical, curved round 

 farinaceous albumen. Small herbs. Leaves opposite, without 

 stipulas. Flowers axillary, sessile. This order has been re- 

 ferred by De Candolle to Paronychiece, from which it differs in 

 the absence of petals and stipulas, and therefore appears to con- 

 stitute a distinct order, more nearly related to Chenopbdece than 

 Paronychiece, from which the plants chiefly differ in the indu- 

 rated tube of the calyx, from the orifice of which the stamens 

 proceed, and in the number of the latter exceeding that of the 

 divisions of the calyx. The tribe Minuartiece is probably not 

 distinguishable from Sclerdnlhece, notwithstanding the supposed 

 presence of petals, which would perhaps be more properly 

 called abortive stamens. All the plants contained in this order 

 are uninteresting weeds, of no known use.
