the long Fl.-stalks and Phyll. rather with C 

 canum. In the small L. of the flowering- 

 branches, and in the Bracts, it is intermediate. 

 Another form differs from C. oleraceum in 

 having somewhat deciUTent L., more sjjines at 

 base, and narrower and shorter braets. Moist 

 m,eadows. e. G. — N^egeu in Koch. 



13. carniolicum. Fl. sessile, crowded, 

 3 or 4 together, somewhat globose. Bracts 

 linear, pectinato-eiliate. PhyH. linear, pubes- 

 cent, without a keel. L. cUiato-spinose, bearing 

 nifescent hairs on the nerves, not webby.

14. spmosissimum. PL sessUe, crowded. 

 Bracts laciniate, very spinose, far exceeding 

 flowers. Phyll. ending in spines as long as 

 themselves. L. elliptico-lanceolate, sinuato- 

 lobate. p. 7, 8. Moist mountains. Alps.

HYBRIDS. 



1. oleraceo-s^inosissimum. L. of C. olera- 

 ceum. PI. of C. spinosissimimi. Bracts in- 

 termediate. Moist meadows in the Bavonnax 

 at Bex. 



2. sjtinosisshno-Tinsithales. L. oiC.Erisi- 

 thales, but narrower and more thorny, with 

 shorter and broader segments, and the sinuses 

 between the teeth more obtuse. PL of C. spi- 

 nosissimimi, but the Phyll. shorter and more 

 spreading, and less thorny. Bracts interme- 

 diate. Meadows, s. Tyrol. 



Another form, more closely resembling Eri- 

 sithales, occm'red in the garden at Erlangen, 

 from seeds of C. spinosissimum. — N^geli in 

 Koch. 



3. rivulari-spinosissimum. L. resembling 

 those of C. spinosissimum. PL and Inflores- 

 cence more like those of C. rivulare. Mea- 

 dows. Mt. Cenis. — N^geli in Koch. 



4. heterophyUo - spinosissimzim (C. rigens, 

 DC; C. antarcticus,'^iiiL). Lower L. some- 

 what webby beneath, and resembling more 

 those of C. spinosissimum. Upper L. and PI. re- 

 sembling those of C. heterophyllum. Braets 

 intermediate. PL milky or pm-ple. 



Another form approaches more to Q. spino- 

 sissimum, with PL often yellowish. Moist 

 mountain meadows. Sw. — N/Egeli in Koch, 

 C. controversum, DC, probably belongs to this 

 hybrid. 



5. acauli-spinosissimwm. Some specimens 

 have nearly the L. of C. spinosissimum and PL 

 of C. acaule ; in others the characters are 

 more intermediate. Mountain pastures. Sw. 

 rare. — NiEGELi in Koch, 



15. Bertolonii. PL few, crowded. Bracts 

 pectinate, vei^ spinose. Phyll. lanceolato- 

 linear, acuminate, mucronate. Stem branched. 

 L. bipinnatifid, very spinose. b. 8. Mts. of 

 Carrara. 



16. glabrum. PL crowded, on short, stalks. 

 Bracts pinnatifid, spinose, hardly exceeding 

 flowers. Phyll. erect, spinescent. Stem simple. 

 L. pinnatifid, spinoso-dentate, hauless. p. 

 Torrents. Heas and Venasque, eentr. Pyr. 



17. microcephalum, " L. lanceolate, pin- 

 natifid, at first webby above, densely tomentose 

 beneath. Stem-L. auriculato-semiamplexicaul. 

 Segm. of all bipartite, spinoso-subulate. Cal. 

 webby. Outer Phyll. lanceolate, on an ovate 

 or oblong base, spinose, somewhat narrowed ; 

 innermost lanceolato-Linear, spinescent. p. 7, 8.

18. Erisithales. PL crowded, nodding, 

 yellow. Stalks densely pubescent, nearly leaf- 

 less. Phyll. lanceolate, spreading horizontally 

 from the middle; glutinous, not webby. L. pin- 

 natipartite. Segm. lanceolate, acuminate, re-

HYBRIDS. 



1. palustri-Erisithales. Eoot, Stem, and 

 L. very like those of C. Erisithales, except 

 that the latter are decm-rent and more thorny. 

 PL Kke those of C. palustre, but rather 

 larger, and with somewhat spreading phyUaries. 

 Inflorescence intermediate. Garden at Tvu'in. 

 — N^GELi in Koch. 



2. Erisithali-heterophyllum (C. paucijlorus, 

 DC). The L., webby beneath and green 

 above, and the tomentose staUv, recall the cha- 

 racters of C. heterophyllum ; the crowded, nod- 

 ding, subrotund PL and glutinous Phyll. are 

 like those of C ^mi^/iffto. El. purple. Moun- 

 tain meadows. Alps. — NiEGELX in Koch.

 crowded, erect. Sialics white, woolly. Phyll.
