 syst. veg. but not of Thunb. Portulaca paniculata, Lin. spec. 2. 

 p. 640. Talinum fruticosum, Willd. spec. 2. p. 864. The 

 calyx is said to be of 5 sepals, but this assertion we suspect to 

 be erroneous.

 p. 141. T. patens ft, Willd. spec. 2. p. 863. T. dichotomum, 

 Ruiz et Pav. syst. fl. per. p. 118. This species is very nearly 

 allied to T, patens, but differs in the flowers being yellow, not 

 red or purple, as in that plant, and the plant is probably bien- 

 nial.

 journ. vol. 3. p. 354.) stem shrubby, erect, branched a little ; 

 branches striated, angular ; leaves flat, linear, mucronate (when

 simple raceme. Tj . D. G. Native of Chili, in the Jarillal, and 

 along the foot of the mountains near Mendoza, at an elevation 

 of 3000 to 4000 feet above the sea. Flowers about a fourth of 

 an inch in diameter, yellow, fading to red. The stem appears 

 not to be at all fleshy, according to the dried specimens.

12 T. POLYA'NDRUM (Ruiz et Pav. syst. fl. per. p. 115.) leaves 

 roundish-obovate, acuminated ; flowers racemose, polyandrous ; 

 petals obcordate, quite entire. . F. Native of Peru, on the 

 hills called Lomas towards Pongo. Herb a foot high, noxious 

 to cattle. The rest unknown. 



Polyandrous Talinum. PI. 1 foot. 



13 T. CRENA'TUM (Ruiz et Pav. 1. c.) leaves roundish-ob- 

 ovate, acuminated ; flowers racemose ; petals crenulated ; sta- 

 mens about 20. Native of South America, on hills about 

 Pongo in the province of Atiquipa. Herb a foot high, and is 

 called by the natives Langua de Vaca, as well as the preceding 

 plant. The rest unknown.

 caulescent; leaves linear-spatulate : lower ones on long petioles; 

 margins naked : superior ones and sepals acutely keeled, glan- 

 dularly ciliated on the back ; flowers pedunculate, axillary. . 

 H. Native of the north-west coast of America, south of Co- 

 lumbia. The habit is that of a species of Talinum, without hav- 

 ing seen the flowers ; it may, however, when better examined 

 turn out to be a species of Calandrinia. Root annual, rather 

 fusiform. 



Menzies's Talinum. PI. -^ foot. 



Cult. Pretty succulent plants, most of which require the 

 heat of a stove ; a mixture of loam, peat, and sand, or any 

 light soil will suit them ; and cuttings of them are very readily 

 rooted. The seeds of the annual species may be reared on a 

 hot-bed, and afterwards planted out in the open border about the 

 end of May.
