CLASS V. ORDER I.] PULMONAUIA. 221 



b!y with the liue blue or varied purple of the full expanded blossoms, 

 densely crowded into a long terminating spike: it would be a much 

 greater ornament to the flower border than numerous other plants that 

 are cultivated with much care and great trouble. 



The rigid hairs with which the whole plant is covered, are deserving 

 the student's minute examination, those of the stem arising from a 

 dark rounded callous tubercle, while those upon the leaves are from 

 the centre of a flatfish circular scale, of a vitreous appearance, delicately 

 striated with lines radiating from the centre, and having a minutely 

 crenated margin. 



Varieties are occasionally met with, having the corolla white, and 

 sometimes rose colour ; the length also of the corolla, as well as the 

 stamens, is various, and frequently the whole appearance of the plant 

 is much altered as it advances to maturity, by the elongation of the 

 spikelets, which are sometimes lengthened into leaf branches six or 

 eight inches long, and the segments of the calyx, as the seeds ripen, 

 are elongated. 



We have several times found luxuriant plants growing in a warm 

 situation, near Worksop, Nottinghamshire, having much the character 

 of E. pustulatum, which is distinguished by being rougher, the tubercles 

 larger, the tube of the corolla as long again, the stamens inserted 

 higher in the tube, and more spreading. It is not of uufrequent oc- 

 currence on the continent, and it is not improbable that it may be 

 found in England. In the northern parts of Portugal I have found it 

 very abundant, together with E. violaceum, a species readily distin- 

 guished from either of the above, and introduced into the British Flora, 

 from having been found at Jersey. We can scarcely admit its claims 

 to this rank, but its character may be a guide to the student E. vio- 

 laceum. — Linn. Stem herbaceous, branched, hispid, leaves ovate, 

 lanceolate, the lower petiolated, the upper oblong, cordate, and some- 

 what amplexicaul at the base, spikes simple elongated, stamens as 

 long as the corolla. 



Habitat. — " Plentiful on the sandy grounds about St. Hilary, 

 Jersey. — Kay. Since found in the same spot by Captain Fiulay, and 

 by Mr. Trevelyan." — Hooker. 



Annual or biennial ; flowering in August. The spikes are lax, few 

 flowered, of a beautiful violet-blue colour. 



GENUS II. PULMO'NARIA.— Linn. Lungwort 



Nat. Ord. Boragi'ne^. De Cand. 



Gen. Char. Calyx bell-shaped, with five angles, five cleft. Corolla 

 funnel-shaped, five-lobed. Stigma obtuse. — Name from Pulmo, 

 the lungs, froui its supposed virtue in affections of the lungs.
