flexed, harcQy exceeding groove of internerve. 

 Lts. obovate. Stip. subulate, dentate, a. 4, 5.

 tened at each. end. Leg. obHeiuely rcticolate.

 not furrowed. 

 i. Edges touching each other. 



27- muricata. Prostrate. Helix subglo- 

 bose, (outer sutm-e nearly flat, Guss.,) not fur- 

 rowed. Spines conical. Seeds somewhat reni- 

 form, hay. Lts. rhombeo-ovate, dentate. Stip. 

 ciliato-dentate, (or entire, Guss.) (Margins of 

 Turns not touching, Koch.)

 compact. Outer Suture thick, flat, fm-rowed. 

 Spines conical, short. Lts. rhombeo-obovate. 

 Stip. laciniate. Stallcs many-flowered, a. 4, 5. 

 Fields, s. Eur. 



29. oliviformis. " Villous. Helix cylin- 

 drico-ellipsoid. Outer Sutui'c at last flattened, 

 1-nerved. Spinules thick, conical, straight. 

 Stalks 1-2-flowered. Stip. dentato-ciHate. a. 

 4, 5. Fields, s. Sic." — Guss. The descrip- 

 tion indicates this to be very near to M. 

 sphserocarpa. 



30. Murex. Villous. Helix cylindrical, 

 flat at each end, compact, hairless. Outer Su- 

 ture broad, keeled. Spines subadpressed. a. 

 4, 5. s. Sic. 



ii. Edges not touching. 



8L tribuloides. Prostrate, hairy. Helix 

 cylindrical, of five tm'ns. Leg. lacimoso-rngose, 

 with radiating veins in the middle. Middle 

 nerve narrow, rising above insertion of the 

 thick, divergent, hooked, and generally groove- 

 less spines. Stalks 1-2-flowered, much shorter 

 than L. Standai'd twice as long as keel. Stip. 

 laciniato-dentate. a. 4, 5. Fields, s. Em*. In- 

 cludes M. Mm'cx of Gussone. 



32. littoralis. Helix cylindrical, compact. 

 Suture broad, from the large, rounded, lateral 

 nerves. Tm-ns about 5. Spines radiating, very 

 sKghtly grooved. Veins few, radiating, not 

 prominent. Fl. 2-6. Standard equal to keel. 

 Stip. ovate, setaceo-dentate. a. 4-6. Sandy 

 shores, s. Em*. Includes M. arenaria. 



33. Gerardi. Prostrate. Helix compact, 

 oblate, veiuless, covered (with glandular hairs, 



Guss.) with small points, and often with tufts 

 of hairs. Suture thick, rounded. Upper spines 

 not grooved, hooked, a. 4, 5. Uncult. s. Eur. 

 Includes M. agrcstis. 



84. ne^lecta. " Villous. Helix globoso- 

 eUipsoid, closely covered with glandular hairs, 

 compact. Outer suture acute, pitted. Spines 

 spreading. Stip. ciliato-dentate. Stalks 1- 

 flowered, exceeding L. a. 4, 5. Low fields. 

 Sic." — Guss. This and Sp. 35 are perhaps 

 varieties of M. Gerardi. 



85. rigidula. Prostrate. Helix cylindri- 

 cal. (Spines hardly diverging, DC.) Lts. obo- 

 vate. Stip. dentate at base. Stalks 2-8-flow-' 

 ered. a. s. Fr. Gussone considers this as 

 perhaps his olivifonnis ; Bentham, as a variety 

 of Gerardi ; Koch, of tribuloides, but the ri- 

 gidula of Thulliers he puts to M. Gerardi. 



36. marina. Densely tomentose. HeHx 

 cylindrical, rather loose. Margin obtuse. Mid- 

 rib almost sunk between the lateral nerves. 

 Veins oblique. Spines radiating, remote, some- 

 times wanting, not grooved. Seeds yellow. 

 Lts. and Stip. quite entire. Fl. numerous, p. 

 5, 6. Sandy shores, s. Em\ Koch says 

 that the helix- is open in the centre ; I find 

 it so only in the upper curves. 



13. Spines furrowed. 

 i. Bach of Legume keeled. 



37. lappacea. Helix loose, of 3^ tiu^is. 

 Leg. obliquely reticidate. Sntm'e thin, some- 

 what acute. Spines long, hooked. Seeds 

 yellow. Lts. obeordate. Stip. ciliato-den- 

 tate. a. 4, 5. Grass and fields. Sic. 



ii. Back of Legume rounded. Base of 

 Spines extending to centre. 



a. Legume not veined on the margin. 



38. minima. Hehx spherical, somewhat 

 loose, of 3-5 tm-ns, all armed. Leg. hairy, 

 veinless. Spines deeply grooved. Seeds yellow. 

 Lts. obovate or obeordate. Upper Stip. nearly 

 entii'e. Stalks about 3-flowered. a. 5, 6. Dry 

 grassy. 



j8. grceca, DC. b. or p. Abruzzi. 



7. recta, Guss. a. Leg. somewhat veined. 



39. laciniata. Helix globose, compact. 

 Lateral Nerves small, close. Spines numerous, 

 straight, hooked, grooved. Seeds bay. Lts, 

 cuneato-lineax, inciso-dentate, trimcate. Stip. 

 ciliato-dentate. a. 5, 6. Port Juvenal.
