The spur on the calyx oiA.fasciculata was, 

 I believe, first noticed by M. Boissier. In the 

 ' Prodromus ' of De Candolle, this writer de- 

 pends much on the hairiness of the calys, con- 

 fined to the ribs, or spreading over the whole 

 surface. I find that in species with the latter 

 character, the hairs are stronger and more nu- 

 merous on the ribs than in the intervening 

 spaces 1 and in those with the former, that a 

 few small hairs sometimes occur in the inter- 

 val, and those on the ribs in the upper part of 

 the tube occupy so wide a space that the inter- 

 , val is often hai-dly perceptible. Still, I think 

 it is in general a recognizable character, and, as 

 such, have noticed it. The hollow at the base 

 of the calyx also, fii-st made use of by him, ap- 

 pears to me to be almost always nearly round, 

 or broadly ovate, or oval. I have only noticed 

 it when it is stated to deviate considerably 

 from this form.

A. Calyx furnished with a spur. 



1. fasciculata. Smooth, shruhby, densely 

 leafy. L. linear, entire, channeled, 1-nerved, 

 acute. Cal. ending rather abruptly in 5 very 

 short awns. w. 5, 6. Sandy shores. Cors. Sard. 



2. Soleirolii. " Stem shrubhy ; upper 

 part leafy. L. fascicled, revolute beneath, 

 finely channeled, very narrow linear, somewhat 

 pungent. Scape quite smooth, three or four 

 times longer than L. Bracts somewhat acute. 

 Teeth of Cal. aristato-acuminate, much shorter 

 than corolla. s.S. Maritime rocks. Calvi." 



— DuBY. The Spur is not mentioned ; I only 

 suppose it to exist from analogy. 



B. No Spur to Calyx. 

 i. Spicules sessile. 

 a. L. all similar. 



* L. \-nerved, the sides almost parallel 

 throughout . 



3. pubigera. " Shrubby at base. Stems 

 short, naked at base, tufted. L. in rosettes, 

 short, linear, about as wide as the scape, 1- 

 nerved, rigid, somewhat 3-edged, rather blunt; 

 upper part channeled, dotted, obtusely keeled. 

 Heads small. Bracts altogether scariose : the 

 lower shorter, ovate, somewhat acute ; the 

 others obtuse, sometimes with a mucro. Pedi- 

 cel half as long as tube of calyx. Basal Pit 

 oblong. Tube of Cal. haiiy all over : border 

 longer than tube. Div. ovate, short, ahruptly 

 awned. xf. Isl. of StaflTa." — Boiss. 



4. ruscinonensis. " Quite smooth (shrub- 

 by at base, Boiss.). L. much crowded, linear 

 or somewhat lanceolato-linear, dentate, quite 

 entire, flaccid. Scape about twice as long as 

 L. Bracts rather broad ; outer generally fall- 

 ing short of flowers, cuspidato-acuminate ; in- 

 nermost equalling flowers, emarginate or entire 

 (sometimes with mucro, Boiss.). Ribs of 

 tube of Cal. hirsute (only on nerves, Boiss.). 

 Teeth with a mucro twice as long as them- 

 selves, p. 5, 6. Port Vendre. CoUioure." — 



GlRAED. 



5. maritima. Outer Bracts broad, obtuse, 

 somewhat cuspidate ; inner pointless. Tube of 

 Cal. hairy all over. M. lilac, p. 7, 8. Sea- 

 coasts. 



6. pubescens. Outer Bracts shortly tri- 

 angular, the herbaceous back forming a point 

 beyond the membrane ; inner longer and very 

 obtuse. Pedicel as long as the tube of calyx. 

 Tube hairy only on the ribs. p. 7, 8. Sea- 

 shores. — -Boiss. 



7. Halleri. " L. short, somewhat chan- 

 neled, without a mai'gin. Outer Bracts smaE, 

 ovate, with a short mucro; inner twice as 

 large, ovato-subrotund, with a broad mai'gin, 

 equalling calyx of fruit. Pedicel half as long- 

 as tabe of calyx. Tube hairy only on the ribs. 

 p. Hartz. Perhaps a var. of A- elongata."'

8. leucantha. Outer Bracts lanceolate, 

 acuminate ; inner obtuse, pointless : all shorter 

 than head, PL brilliant white, p. Very high..
