Composite.

— Stem with erect branches. Caul. Is more or less numerous 
(3—10) and gen. broader than in the last. Invol. Is with 
simple (often rather numerous; comp, the var.), but 
without stellate, hairs, or the latter only scattered; the 
outer Is spreading (?). Rad. Is gen. with entire edges. 
(Not to be confounded with H. scorzonerifolium calvum). 
•H. glaucum bupleuroides Grml., H. graminifolium Gaud, 
a. and b.!—b . juratense Grml. N. Beitr. Ill, 15- (gramini¬ 
folium legitimum Gaud, from Saleve!) Heads larger; 
invol. Is broad, very distinctly imbricate, without simple 
hairs, the outer ones appressed.—As the last, but more 
widely distrib. (in G. also); b. Jura! Saleve! Alp. of 
Bex! 7. bupleuroides Gmel. 1376. *) 
Section 2. Villosa. 
37 (33). L/8 firm as in the Glauca; when dried and held to 
the light only showing an indistinct net-work of veins; 
almost always glabr. above, with edges entire or 
toothed; the caul, narrowed or enlarged at the base. 
(Invol. Is fairly equal, i. e. the outer ones not sensibly 
broader) ......... 3S 
— Ls soft, showing a more distinct net-work of veins when 
dry, glabr. or hairy above, often more or less toothed, 
the caul., when present, gen. narrowed at the base. 
(Invol. Is fairly equal) ...... 30 
— Lis (distinctly glaucous) soft, showing a distinct net¬ 
work of veins when dry, gen. hairy on both sides and 
with entire (rarely toothed) edges; the caul, enlarged 
at the base, very often almost half-clasping. (Inner 
invol. Is fine-acuminate.) Type of H. villosum . 43 
38. Ls with entire edges or distantly denticulate, the rad. 
still fresh at the time of flowering; the caul. (2—4) 
lanceolate, gen. fairly broad at the base. Invol. ls acute 
or acuminate. This species has the narrow, somewhat 
firm ls of H. glaucum, the structure and hair qualities 
of the invols of H. elongatum. Stem stiff, rather flexible, 
often rather reddish as also the teeth of the ls. H. gla- 
bratum Koch.**) H. flexuosum var. c. and d. Gaud.! 
—Rarely varied; rather glabr., the invol. only slightly 
villous (v. calvum; a var. wicli needs not be confused 
with H. bupleuroides, the invol. ls of which are obtuse 
*) H. Tatrae Grisb. (bupleuroides glaberrimum Fr.) has the invols of 
H. juratense, but is hypophyllopodous, and has 15—20 caul, ls ; according to 
Levier, near Bormio.— H. porrifolium L. has very narrow Is (almost like 
grass), it is found by Lake Como ; but not in Switzerland. 
**) H. glabratum Hopp. Slender, often 1-headed ; ls glabr. ; invol. Is 
narrowed to a longer, but rather blunt, point. Hitertho we have only met 
with it in the Tyrol.
