BRITISH PULMOXAEIAS 237 



quite half tlie leaf surface. The only other Dorset specimens I have 

 seen (East Morden, Mansell Pleydell : Herb. Mus. Biit.) have 

 conspicuous white spots. These Dorset plants have a facies rather 

 distinct from the Brockenhurst ones, hut since Bromlield describes the 

 same variation of spots for the Isle of Wight plants they are probably 

 the same. The distribution of this form requires to be investigated, 

 for none of the numerous Isle of Wight and New Forest specimens 

 seen hi Herb. Mus. Brit., Herb. Kew, and Herb. Bailey show the 

 confluent spots. 



The spotting is much more varial)le tlian Kerner would lead us to 

 suppose. In spite of his categorical statements, specimens from the 

 Khine provinces which he refers (to judge from the distribution 

 given) to P. tuherosa occasionally show very faint shadowy spots. 

 But the range of variation and the frequency of spots in the British 

 plant are evidently those of P. lom/ifolia, for Kerner says that of 

 this the spots are usually not numerous, sometimes on single leaves 

 only two or three, or very rarely none. 



P. anc/ustifolia (^aziirea) appears (to judge ex sicco) to be a very 

 distinct species. It is Avell rej^resented in numbered exsiccatai — - 

 Keichenbach 238, Schultz 323, 323 bis, Fries i. 14, Woloszczak (ti. 

 polon. exs.) 463, Dorfler 5137, Kerner (Fl. Exs. Austr.-Hung.) 927 ; 

 all as P. angustifolia except Reichenbach's which is named P. cizurea. 

 The broader- leaved southern fcjrm (var. latifolia Bouy) is perhaps 

 not identical : the fact that Kerner could draw no clear line between it 

 (r/! Paulin 169, as P. amjustifolia) and the typical form may be 

 merely due to the presence of crossing. The phrase " or oblong 

 lanceolate " in the description given of the radical leaves refers to 

 this plant. The typical form is very distinct in its habit and leaf 

 shape, and especially in its colour, a most beautiful blue. Ray (Hist. 

 i. 489: 1686) says " flores colore caeruleo adeo eleganti nitent, ut 

 GentianeUae vernae floris venustatem si non superare, attamen 

 proxime aemulari videantur." I have seen specimens of Pulmonaria 

 azurea from Miss Jekyll's garden of which the remark might well 

 have been made. I was unfortunately unable to compare this fresh 

 with British plants, but I think one might certainly call the latter 

 comparatively purplish-blue, although I thought them almost " azure " 

 before seeing Miss Jekyll's plant. 



Kerner' s other characters are of variable worth. The shape of 

 the radical leaves when mature is characteristic. The British plant 

 is evidently, on that character, P. loiujifolia, it being remembered 

 that, as Kerner points out, the leaves are very variable in breadth,- 

 the narrower simulating P. angustifolia, the broader P. tuherosa, 

 although they always have a somewhat different look which is difficult 

 to define. A series received fresh (July 23) were from 20 to 34 cm. 

 long, 3-5 cm. broad, the laminae mostly about 4-5 times as long as 

 broad, the whole leaf usually about 6 times, but sometimes 9 times : 

 in Herb. Mus. Brit, is a leaf 60 cm. long and 9 cm. broad. They are 

 usually longer than the fruiting stems, but there seems considerable 

 variation in this respect in all the species. The flower stems of 

 P. azurea are in wild specimens rather dwarf, but those from 

 Miss Jekyll's garden were over 20 cm. high. These latter have less 

 naiTow and less " erect " cauline leaves, just as small narrow-leaved
