olum. The latter, from which our present drawing was 

 made, excited very great interest at the meeting of the 

 London Horticultural Society on the 4th of October of the 

 present year, 1842, and, after some high compliments had 

 been paid to the successful cultivator, the Society's silver 

 medal was awarded to Mr. Veitch, for this interesting addi- 

 tion to our greenhouse plants. The tubers were sent over, 

 only two months previously to the day of exhibition, from 

 Chili, by Mr. Veitch's Collector, Mr. Lobb. I am not 

 aware that a description is anywhere given of this plant ; 

 but there is no reason to doubt its being the T. azureum of 

 Mr. Miers' e( Travels." The species has not the gay ap- 

 pearance that we are accustomed to see in the species of 

 Indian Cress previously known to us : but it is a graceful 

 and elegant plant, and with the foliage somewhat resem- 

 bling that of T. tricolorum, it has flowers much more like 

 those of the common violet. In the structure of the blos- 

 soms, however, it very much resembles T. brachyceras 

 (Bot. Mag. tab. 3851). 



Descr. Roots tuberous. Stems slender, herbaceous, 

 much branched and twining, glabrous, as is every part of 

 the plant. Leaves alternate, peltate, divided almost to the 

 base into about five, lanceolate or linear segments ; their 

 petioles cirrhiform. Peduncles flexuose, slender, longer than 

 the leaves. Calyx of five deep, almost ovate, slightly 

 spreading segments, tapering at the base into a short, coni- 

 cal spur. Petals five, clawed, nearly equal, obcordate, vio- 

 let-blue colour (deep violet when dry), emarginate and 

 slightly erose. Stamens eight, oblique. Germen three- 

 lobed. Style short, thick. Stigma dentate.
