some New Species of Portulacea^. 355 



tiiargine revolutis angu«tissimis,) pedunculis basi bibracteolatis 

 fructiferis arcuato-deflexis axillaribus racemum simplicem aemu- 

 lantibus, capsula globosa, stylo filiformi, stigiiiatibus, 3 patulis. 



T. polygaloides. Gill. mss. 



Hab. In the Jarillal, and along the foot of the mountains 

 near Mendoza ; elevation above the sea from 3000 to 4000 feet. 

 (October to February, 1822.) 



Flowers about a fourth of an inch in diameter, yellow, 

 becoming red, as in some species of CEjiothera, by drying. 

 Placenta stipitate, central. Seeds numerous, cochleate, or almost 

 reniform, longitudinally furrowed : as they are not sufficiently 

 mature, we have not observed their internal structure. The 

 stem is brittle ; it appears to be not at all carnose, but rather 

 woody, if one may judge of it in the dried state. 



Calandrinia. 



1. C. cistijlora. — Tota glabra, caule adscendente sufFructicoso^ 

 ramis basi foliosis versus apicem nudiusculis, foliis lineari- 

 ianceolatis acutissimis, racemo terminali paucifloro, pedicellis 

 elongatis, bracteis minutis foliaceis, sepalis ovatis acutis, stami- 

 nifeus plurmis. 



C. cistiflora. Gill. mss. 



Hab. On the Andes of Mendoza and Chile, at the following 

 stations: — El Portezuelo del Valle Hermosa, La Quebrada de 

 Fray Carlos, La Cuesta del Inga, El Alto del Chueco de San 

 Pedro Nolasco ; elevation above the sea from 9,000 to 10,000 

 feet. (March, 1826.) 



The flower is pretty large and purple. This species appears 

 to me to rank next C. lingulata D.C. 



2. C. affinis. — Glabra acaulis, foliis elongatis linearibus obtusis 

 in petiolum attenuatis, petiolis in basin induratam inbricatis 

 dilatatis, pedunculis radicalibus unifloris nudisfolio dimidio 

 brevioribus, staminibus 15. 



C. affinis. Gill. mss. 



Hab. On the Andes of Chile at El Cerro de San Pedro 

 Nolasco, April, 1826. 



This is closely allied to C. acaulis H.B.K. ; but in addition to 

 other characters, seems to differ materially in the number of 

 stamens : it was, however, very difficult to see how many there 

 were in the specimen 1 possess of C. affinis; there are cer- 

 tainly more than ten, and in one flower I observed fifteen. 



3. C. diffusa. — Caulescens glabra diffusa, ramis basi foliosis 

 superne nudiusculis l~2-floris, foliis spathulato-lanceolatis acutis 

 integerrimis, floribus terminalibus, sepalis orbiculatis margine 

 integerrimis. 



C. diffusa. Gill. mss. 



Hab. On the Andes of Chile near El Paso de los Peuquenes; 

 elevation above the sea about 10,000 feet. (March, 1826.)
