 there is every possibility of a new race of hardy Prim- 

 roses, distinguished by their remarkable orange- 

 scarlet-colored flowers, being developed from these 

 two species. A shady position, fairly heavy loam, 

 cow dung, and an abundance of water at the roots 

 are the essentials for the successful culture of these 

 Primroses. An ideal spot is the side of a woodland 

 stream free of rank weeds. 



The third species (P. Veitchii) is a true perennial, 

 with leaves resembling those of P. obconica but with 

 a dense felt of white hairs covering the underside. 

 The flowers are of a pleasing bright rose color and are 

 freely produced in whorls on scapes from one to one and 

 a half feet tall. A hardy P. obconica with non-poison- 

 ous leaves sums up P. Veitchii. A light loamy soil rich 

 in leaf-mold and a moderately dry situation are neces- 

 sary for its successful cultivation and under such con- 

 ditions it will naturalize itself. 



Although not hardy except in the warmer parts of 

 this country Corydalis thalictrifolia and C. Wilsonii 

 deserve mention here. The first has leaves rather 

 fleshy in texture in shape resembling those of a 

 Maidenhair Fern, and very numerous erect racemes 

 of large clear yellow flowers. The other is a smaller 

 plant with finely cut leaves, covered with a white
