322 Borraginacee—A nchusa, 
There are numerous other species, but the above is the only 
ornamental plant of any value. 
5. PULMONARIA. 
Perennial tufted herbs with simple flowering stems and 
terminal cymes. Calyx angular, deeply 5-partite. Corolla 
funnel-shaped, 5-lobed, with 5 tufts of hairs alternating with 
the stamens, the latter included. Nuts 4, turbinate, smooth, 
sessile on a flat receptacle. There are five species, natives of 
Europe and North Asia. The name is from pulmo, the lungs, 
in allusion to the supposed efficacy of these herbs in lung com- 
plaints ; hence the English name Lungwort. 
1. P. officindlis.—Leaves radical, ovate-lanceolate, on long 
petioles, often spotted with light green. Flowers red, changing 
to blue or purple. This is a common plant in old gardens, and 
generally known by the blotched leaves, though there is a 
variety without blotches and another with white flowers. A 
native of various parts of Europe, and occasionally found in 
a semi-wild state in Britain. 
P. angustifolia, similar to the last, with narrow leaves and 
pink ultimately bright blue flowers, is believed to be truly 
indigenous in Hants and Dorset. P. Sibiriea is of more 
slender habit, with uniformly green leaves and deep blue 
flowers. They all flower in Spring. 
Merténsia Virginiea, Virginian Cowslip, is an allied per- 
emnial plant from 1 to 2 feet high with smooth pale green 
foliage and pale blue, puiple or white flowers in terminal 
clusters. It is separated from Pulmondria on account of the 
stamens exceeding the corolla-tube, and the nuts being fleshy 
when fresh. Jf. maritime is a native species, found on the 
western coast. 
Ondsina Teiricum is a handsome tufted herbaceous plant 
less than a foot high, with lanceolate hispid leaves and large 
golden yellow flowers in drooping clusters. The stamens 
exceed the naked corolla, and the nuts are stony. There are 
several other species, but this is one of the best. 
6. LITHOSPERMUM. 
Hispid or hairy annual or perennial herbs, sometimes shrubby 
at the base, often of prostrate babit. Flowers in bracteate 
cymes. Calyx 5-lobed to the base. Corolla funnel- or salver- 
shaped ; throat naked, or with 5 tumid folds; limb spreading.
