Lachen^ia tricolor; tender bulb from Cape of Good Hope; with 

 lanceolate soft leaves blotched Avith purple, and a raceme of small, rather sin- 

 gular than handsome, greenish-purple and yellow flowers, its erect divisions 

 connivent, the three interior longer.

 flowered bulbs, chiefly from California and Oregon, hardly any quite hardy N.
