 petals, and but only one style, and stigmas have been per- 

 ceived. 



Bristle-bearing Rupture-wort. PI. prostrate.

 humble, much branched, tufted ; branches short, villous ; leaves

2. Polygonoldece (plants with the habit of Polygonum). 

 Stems erect, dichotomous at the apex. Flowers glabrous, disposed 

 in loose cymes. Perhaps a proper genus. 



12 H. POLYGONOIDES (Cav. icon. 2. t. 137.) erect, glabrous, 

 shrubby ; branches dichotomous at the apex ; leaves ovate, cus- 

 pidate, distant. Jj . H. Native of Mauritania, near Mascar ; 

 and on the hills of Spain, in Valentia, as well as in Provence. 

 Illecebrum suflruticosum, Lin. spec. p. 298. Paronychia suf- 

 fruticosa, Lam. fl. fr. 3, p. 230. Herniaria erecta, Desf. alt. 1. 

 p. 214. H. Joanneana, Roem. et Schultes, syst. 6. p. 297. 

 This species differs from Paronychia, in the fruit being indehis- 

 cent. The habit is very dissimilar from the other species of 

 Herniaria, but emulates Anychia and Paronychia.

f Species not sufficiently known. 



13 H. DICHO'TOMA (D. C. prod. 3. p. 368.) stems erect, nu- 

 merous, dichotomous, herbaceous ; leaves distant, oblong, mutic, 

 and are, as well as the branches, powdery from short down ; 

 flowers cymose. 2/ . ? H. Native country unknown. Parony- 

 chia dichotoma, D. C. in Lam. diet. ency. 5. p. 25. Illecebrum 

 dichotomum, Pers. ench. 1. p. 261. "Calyx glumaceous, striat- 

 ed at the base and pubescent, profoundly 5-cleft ; segments 

 bluntish, with scarious margins ; sterile threads 5, alternating 

 with the sepals, and 5 antheriferous ones opposite them, hardly 

 shorter than the sterile ones. Style bidentate at the apex. Ova- 

 rium attenuated at the base. Ovulum one, pendulous, suspended 

 from the top of a thread, which arises from the bottom of the 

 capsule." Adr. Juss. in litt. 1827. 



Dichotomous Rupture-wort. PI. ^ to ^ foot. 



14 H. LENTICULA'TA (Thunb. fl. cap. p. 245.) suffruticose, 

 hairy, decumbent, clothed with cinereous villi ; leaves ovate, 

 fleshy. Tj . G. Native of the Cape of Good Hope. H. incana 

 Capensis, Pers. This is a very obscure species. The Linnean 

 plant under this name, according to Vahl and Smith, is Cressa 

 Cretica ; but we know not what Thunberg's plant is. 



Lenticular Rupture-wort. PL procumbent. 



Cult. All the species are weedy looking plants, most of them 

 with the habit of wild-thyme, and therefore are only worth culti- 

 vating in botanic gardens. The plants grow best in dry light 

 sandy soil, and are increased by seeds.

 Kapiros,karpos, a fruit). Forsk. descr. p. 65. icon. t. 10. Desf.

LIN. SYST. Pentandria, Monogynia. Calyx almost 3-parted, 

 permanent ; segments coloured inside. Petals 5, emulating sterile 

 filaments. Stamens 5, inserted in the bottom of the calyx. 

 Style one, crowned by a simple stigma. Capsule valveless, 1- 

 seeded, covered by the indurated calyx. Diffuse subshrubs, 

 with opposite stipulaceous leaves, usually bearing fascicles of 

 rameal leaves in the axils. Pedicels axillary, solitary, opposite, 

 appearing crowded at the tops of the branches, from the inter- 

 nodes being short. The name of this genus is spelt variously 

 by authors, viz. Gymnocarpos (Forsk.), Gymnocarpus (Viv.), 

 Gymnocarpon (Pers.), Gymnocarpum (Steud.).
