-tART II. PRUNELLA— PULMONARIA. 301 



In addition to the Primroses above described, P. spectabilis, 

 a handsome kind with purphsh flowers and smooth leaves ; 

 P. carniolica ; P. intermedia, allied to farinosa and longijlora ; 

 P. sibirica, allied to P. cortusoides j P. pedemontana and P. 

 Dinyana, are amongst the best of the sorts in cultivation, but 

 most of them are very rare. The singular P. verticillata, . of 

 Arabia, covered with silvery farina and with yellow flowers in 

 whorls, is not hardy. P. Tkomasini, macrocalyx, intricata, 

 suaveolens, stricta, auriculata, Allioni, Clusiana, and mistassi- 

 nica, are either not sufficiently distinct from other and superior 

 sorts or are not ornamental enough to be recommended for 

 general cultivation. 



PRUNELLA GRANDIFLORA.— Z<zr^« Self-heal. . 



A HANDSOME and vigorous plant, with rather soft, sparsely- 

 toothed, ovate leaves, the lower ones about two inches and a half 

 long, and with channeled footstalks longer than the leaves, the 

 upper leaves smaller, and with the footstalks shorter than the 

 leaves. It is, however, not likely to be mistaken for any other 

 plant, and is readily distinguished by its large flowers from the 

 common British Self-heal, which is unworthy of cultivation. 

 There is a white as well as a purple variety, both handsome 

 plants, that thrive in almost any ground, but prefer a moist and 

 free soil and a position somewhat shaded. They are apt to go 

 off in winter on the London clay, at least on the level ground. 

 Well suited for the mixed border, for banks, or for naturahsation 

 in copses, &c. A native of Continental Europe ; flowering in 

 summer. 



PULMONAELfi. OyFIClNALlS.— Lungwort. 



A SOMEWHAT rare British plant, but often grown in cottage gar- 

 dens, and, if hot sufficiently ornamental for the rock-garden, very 

 desirable for borders and spring gardens. It has coarsely hairy 

 root-leaves, nearly oval in outline and acute at the apex, abun- 

 dantly marked on the upper surface with white blotches ; the 

 flowers at first rose and then blue, on stems from six inches to a 

 foot high, abundantly produced in spring. The blue-flowered 

 P, angustifolia is by some botanists united with this species, and 

 there is a white and a spotless variety in cultivation. The Lung- 

 wort and its varieties are very vigorous and hardy, thriving on
