 axillary ; leaves linear-lanceolate, pubescent, glandless. Native 

 country unknown. Leaves revolute, sessile, strigose above, but 

 clothed with stellate tomentum beneath. Peduncles branched, 

 bractless. (ex Spreng. syst. 1. p. 942.) . 



Entire-leaved Turnera. PL ? 



47 T. VIRGA'TA (Willd. rel. 1. c.) leaves ovate, serrated, pli- 

 cate, biglandular at the base ; flowers bibracteate ; bracteas 

 linear-setaceous. Q- S. Native of Brazil. 



Twiggy Turnera. PI. -| to 1 foot. 



48 T. CORCHORIFOLIA (Willd. rel. 1. c.) leaves oblong, doubly 

 serrated, tomentose beneath. O- S. Native of Brazil. The 

 rest unknown. 



Corchorus-leaved Turnera. PI. -| to 1 foot? 



49 T. DESVAU'XII (D.C. prod. 3. p. 348.) stem suffruticose, 

 branched ; branches assurgent, hairy ; leaves ovate, obtuse, cre- 

 nately toothed at the base, rather pilose beneath ; flowers axil- 

 lary, on long peduncles. Native of Guiana. T. hirta, Desv. 

 in Hamilt. prod. p. 33. but not of Willd. 



Desvaux's Turnera. PI. 1 foot. 



Cult. All the species of Turnera are elegant plants when in 

 flower, and thrive well in any light rich soil. They seed freely 

 in this country, and may be propagated by that means : cuttings 

 also root freely, under a hand-glass, in heat. The seeds of 

 annual species may be reared on a hot-bed in spring ; and some 

 of the plants may be planted out into the open border, in a warm 

 sheltered situation, where they will probably flower and ripen 

 their seeds, if the summer prove dry and warm. 



II. PIRIQUE'TA (meaning not explained by Aublet). Aubl. 

 guian. 1. p. 298. t. 117. Juss. gen. 294. H. B. et Kunth, 

 nov. gen. amer. 6. p. 127. D. C. prod. 3. p. 348. Burghartia, 

 Neck. elem. no. 1186. Burcardia, Scop, ex Schreb. gen. no. 

 530. but not of Schmied. nor Duham. nor Neck, nor R. Br. 

 Turnera species, Lam. and Willd. 



LIN. SYST. Pentdndria, Tri-Hexagy'nia. Calyx campanu- 

 late. Style 6, or 3 bipartite ones ; stigmas multifid, flabellate. 

 Capsule 3-valved from the apex to the base. Perhaps this 

 genus is sufficiently distinct from the preceding. Habit of Tur- 

 nera racemosa, but which plant is only furnished with 3 styles, 

 not 6. Flowers pedicellate, in the axils of the upper leaves. 

 Pedicels bractless, articulated above the middle. 



1 P. VILLOSA ( Aubl. 1. c.) leaves ovate-oblong, erosely toothed, 

 wrinkled, clothed with rufous villi. Q. S. Native of Guiana, 

 in sand by the sea-side. Turnera rugosa, Willd. spec. 1. p. 

 1504. Poir. diet. 8. p. 145. Turnera villosa, Raeusch. Co- 

 rolla yellow. 



Villous Piriqueta. PI. 2 feet. 



2 P. TOMENTOSA (H. B. et Kunth, nov. gen. amer. 6. p. 128.) 

 leaves oblong, acutish at both ends, irregularly crenate-serrated, 

 pubescent above, clothed with soft hoary tomentum beneath. 

 O- S. Native of South America, between Atures and May- 

 pures, on the Orinoco. Turnera tomentosa, Willd. rel. in 

 Rcem. etSchultes, syst. 6. p. 678. but not of H. B. et Kunth, 

 Corolla yellow. 



Tomentose Piriqueta. Shrub 1 to 2 feet. 

 Cult. The culture and propagation of these plants are the 

 same as for the annual species of Turnera, see p. 70. 



ORDER CIX. FOUQUIERA'CE^E (plants agreeing with 

 Fouc/uiera in important characters). D. C. prod. 3. p. 349. 

 Portulaceis affines, H. B. et Kunth, nov. gen. amer. 6. p. 81. 



Calyx of 5 permanent sepals ; sepals imbricated, ovate or 

 roundish. Petals 5, combined into a tube, inserted in the bottom 



of the calyx or torus ; limb of corolla 5-lobed, regular. Sta- 

 mens 10-12, inserted with the corolla, exserted ; anthers 2- 

 celled. Ovarium free, sessile. Style filiform, trifid at the 

 apex. Capsule trigonal, 3-celled ; valves bearing dissepiments in 

 their middle, which go as far as the centre of the fruit, and there- 

 fore the capsule is 3-celled. Seeds compressed, winged, fixed 

 to the centre of the fruit or axis, few when the capsule is 

 mature, but numerous when it is in a young state. Embryo 

 straight, in the centre of a fleshy albumen, with flat cotyledons. 

 Trees or shrubs, natives of Mexico. Leaves in fascicles 

 when young, in the axils of spines or cushions, quite entire, 

 oblong, and rather fleshy. Flowers scarlet, disposed in a ter- 

 minal spike or panicle. 



This order is separated from Portulacece by De Candolle, as 

 he tells us, (Mem. portul. p. 4.) for the following reasons : first, 

 because their petals cohere into a long tube, of the same nature 

 as that of gamopetalous Crassulacece ; second, because their 

 capsule consists of 3 loculicidal cells, that is to say, which 

 separate through the middle, forming 3 septiferous valves ; and 

 thirdly, because their embryo is straight, with flat cotyledons, 

 and stationed in the centre of a fleshy albumen. They approach 

 the monopetalous Crassulacece in the structure of their flowers ; 

 and Turneracece and Loasece in the form of their fruit. 



Synopsis of the genera. 



1 FOUQUIE'RA. Sepals ovate, mucronate, free, 2 exterior 

 and 3 interior. Limb of corolla spreadingly reflexed. Stamens 

 10-12, hypogynous. 



2 BRONNIA. Sepals roundish; limb of corolla erect. Sta- 

 mens 10.

 M. D. of Paris, and Professor of Medicine there). H. B. et

 Echeveria species, Moc. et Sesse, icon. ined. 



LIN. SYST. Decdndria, Monogynia. Calyx coloured ; sepals 

 ovate, mucronate, 2 exterior and 3 interior, free. Corolla 

 hypogynous ; tube cylindrical, a little arched ; limb spreadingly 

 reflexed, nearly regular. Stamens 10-12, hypogynous, ex- 

 serted ; filaments ciliated below, and cohering together ; an- 

 thers cordate. Ovulas 18, on each placenta, in 2 rows. Fruit 

 unknown. A somewhat spinose shrub. Spikes terminal, erect. 

 Flowers scarlet. Leaves oblong, rather fleshy. 



1 F. FORMOSA (H. B. et Kunth, 1. c.). ^ . S. Native of 

 Mexico. Echeveria spicata, Moc. et Sesse, fl. mex. icon. ined. 

 Flowers flesh-coloured, an inch long. Leaves scattered, accord- 

 ing to Kunth's figure ; but according to the figure in the fl. mex. 

 they are a little narrower and in fascicles : therefore the 2 figures 

 mentioned are very unlike each other. 



Showy Fouquiera. Shrub 6 to 10 feet. 



Cult. A light rich soil will suit this very showy shrub ; and 

 young cuttings will root freely under a hand-glass, in heat.
