 Primulas, Primrose. To this genus belong the celebrated 

 Coivshp, Oxsli'p, Primrose, and the esteemed Auricula. 

 The double varieties of Primrose have originated from P. 

 vulgaris. These are such as carry their flowers on separate 

 pedicles, rising from the root on a small stem. The double 

 varieties are desirable for their beauty, but require the pro- 

 tection of a frame during winter. They are in color red, 

 white, yellow, lilac, purple, and crimson. P. eldtior is the 

 Oxslip, from which all the Polyanthuses have been grown. 

 They are in variety innumerable, and are those whose flow-

 P. suaveolens, P. decora, with P. scotica and P. farinosa, 

 both small, neat species. A shady situation agrees best with 

 them ', and they require loamy soil, free from any kind of 

 manure, except it be fully decomposed. The leaves of P. 

 veris have been recommended for feeding silk-worms. 



Plumhago Larpantea, Lady Larpants, Lead-wort, dark- 

 blue, flowering from July till frost; a very great acquisition 

 to the flower garden ; will require to be covered in winter in 

 the Eastern and Northern States. 



Potentillas are similar to the strawberry in habit and ap- 

 pearance. P. nepalensis, or foronosa, has rose-colored flow-
