388 MR. C. ©. LACAITA: A REVISION OF 
méo. Echium pustulatum Ten.* in herb. Mus. Paris (in arvis siccis circa 
Neapolim a Tenorio lectum) alia planta est, /ccAio vulgari longe atftinior, 
foliorum pube eum hoe vulgari conveniens, diversa satis in bracteis, foliorum 
margine et eosta dorsali rigidioribus lucidis, strigulis brevissimis rigidis 
adpressis bractearum dorsum occupantibus, etc." 
This intermediate var. grandiflorum is represented by the following, 
among many other, examples :— Ò 
11. Portici al Granatello (near Naples), from Tenore as Æ. vulgare in 
Hb. Kew. 
12. Ibidem, from Gussone as Æ. tuberculatum in Hb. Kew. 
13. M. Gargano, from Tenore as E. vulgare in Hb. Kew. 
14. “ In collibus aridis totius Dalmatie," Unio It. 1829 as X. pustu- 
latum in Hb. Kew. 
15. Veglia (Dalmatia), leg. Bauer as Æ. pustulatum in Hb. Kew. 
16. Zara (Dalmatia), leg. A. Braun as £. pustulatum in Hb. Kew. 
The last three obviously represent Koch's conception of E. pustulatum. 
Like typical vulgare this form occasionally occurs with pink corollas, when 
it has been mistaken by Italian botanists—e. y., Bertoloni, Fl. It. ii. p. 347— 
for Æ. angustifolium, Mill. (hispidum Sibth.), which is not Italian t. 
Although I have looked through—somewhat hurriedly—all the French 
specimens of Echium in the Paris Museum and those of M. Rouyt, I have 
found none among them that are undoubtedly identical with Sibthorp’s 
pustulatum. Most so-named Spanish examples are referable either to 
E. Coincyanum, mihi — E. creticum, Willk. et auctt. hisp., non Linn., or to 
E. hispanicum, Asso§ = Anchusa angustis villosis foliis hispanica, Barr. Ic. 577, 
but I cannot speak positively as to others. 
The systematic value of Æ. pustulatum as represented by Sibthorp’s type, 
and its relation to the other forms referred to, remains doubtful. What 
is clear is that the vulgare of northern and central Europe is replaced in the 
Mediterranean, not by one equivalent form, but by sundry * little species,” 
differing from each other as much as from typical vulgare, and that these 
have hitherto been very superficially studied. Herbarium specimens are 
* Tenore usually sent out this form from the vicinity of Naples as vulgare, sometimes as 
tuberculatum, occasionally, as in the specimen here referred to, as pustulatum. True 
pustulatum he sometimes sent out under that name but sometimes as tuberculatum, so that 
his specimens, for which a precise locality is rarely indicated, are valueless for nomenclature, 
I have seen Schouw's Etna plant in hb. Desfontaines, now at Florence; it is like no. 5 
above, and undistinguishable from Sibthorp's specimen.

generously welcomes those who wish to study his magnificent collections.
