410 MR. C. C. LACAITA : A REVISION OF . 
Lapeyrouse of his pyramidale. The herbarium specimen, taken from a plant 
grown in Hort. Ups., consists of one leaf only and two flowering branches 
without the main stem, but is quite unmistakable. A list D of characteristic 
specimens of Æ. pyrenaicum will be found below. The following description 
is founded on French exsiecata from Toulouse, but the Apulian plant seems 
to be larger, with more stiffly horizontal branches; this, however, may be due 
to the impossibility of exhibiting full-sized French plants in herbarium sheets. 
What I must emphasise is that in Italy pyrenaicum and italicum are totally 
different, and inhabit separate areas, as was long ago pointed out by Tenore 
and Gussone (cf. Ten. Fl. Nap. v. p. 330, and Guss. et Ten, in Att. Ac. Nap. 
v. p. 431, 1843). 
It is notorious that pyrenaicum alone is found in Algeria ; it predominates 
in Spain, where italicum apparently only just crosses the border into Catalonia. 
In fact, it is in southern France alone that the two species are often found in 
proximity, and it is precisely there that puzzling forms occasionally occur— 
whether as hybrids I cannot say. 
The Balearic Islands furnish a form with extra hard bristles, but not 
otherwise distinguishable. This is Æ. italicum, var. balearicum, Porta & Rigo 
in N. Giorn. Bot. It. xix. p. 318 (1887), but it must be referred as a variety 
to pyrenaicum and not to italicum. 
ECHIUM PYRENIACUM ; (planta Tolosana) semper unieaule, caulibus 
secundariis nullis, aut rarissime prresentibus, 
Caules e. 50-60 cm. alti., ramosi, ramis inferioribus patentibus, (a) in 
planta luxuriante usque ad 45 cm. longis, ramulos floriferos 15-20 
gerentibus; ipsis ramulis aut simplicibus fere a basi floriferis, aut apice 
in eineinnos geminos fissis; (b) in planta debiliore non ultra 30 em. 
longis, basi usque ad 10 em. foliiferis non floriferis, superne cincinnos 
abbreviatos simplices, raro gominos, gerentibus ; ramis vero superioribus, 
simplicibus, ad cincinnum unicum elongatum reductis. 
Cineinni virginei parum scorpioidei (multo minus quam in Æ. italico), in 
ramis inferioribus laterales pauciflori, quasi ad florum glomerulos post 
anthesin parum elongatos reducti ; in ramis vero superioribus simplicibus 
10-20-flori, ideoque post anthesin usque ad 10-15 em. elongati, suberecti. 
Infldrescentia pyramidalis, latitudine in plantis evolutis altitudinem :equante 
vel etiam superante ; ramis aut horizontalibus, aut (quia inter plantas 
circumstantes constrietis 7) adscendentibus, ita ut plures altitudinem 
axis centralis attingant *. 
* [ suppose this is the character meant by the phrase “rameaux atteignant presque tous 
la méme hauteur, ce qui donne à la plante l'aspecte conique,” which Bonnet uses of his 
italicum, by which, as explained in a previous note, he intends pyrenaicum. But the same 
words are used by Rouy, who does not seem to have noticed that Bonnet transposes the 
two names, of his own italicum which is not pyrenaicum. I am afraid this takes away 
nearly all the value of Rouy’s account of these species. And, indeed, the phrase indicates 
an arrangement of branches which would not produce a cone, but an inverted cone,
