Caulis aphyllopodus 40—50 cm altus striatus subpilosus v. inter folia 
media densius pilosus, superne dense-, inferne parcefloccosus, eglandu- 
` losus, crassiusculus, basi violaceus. Folia caulina inferiora emarcida, 
reliqua 12—18 lanceolata elongata ad 12—15 cm longa 2 cm lata, sursum 
sensim decrescentia, summa magis remota et in bracteas inflorescentiae 
decrescentia, omnia utrimque attenuata sessilia, acuta v. acutiuscula, 
denticulata v. subdentata, gramineo-viridia, subrigida, in margine sub- 
revoluta + dense ciliata, 2—4 mm, et floceis dispersis obsita, utrimque 
subpilosa, in. nervo dorsali praecipue basin versus densius longiusque 
pilosa, superiora in parte aversa subfloccosa, pilis basi bulbiferis. In- 
florescentia laxe paniculata, acladium ad 25 mm longum, rami primarii 
3—5 v. complures, remoti, erecti; ordines axium 3; capitula (5—)8—15 
(v. compluria, sed partim aborta) Involucrum fere ut in H. wmbellato, 
crasse ovatum subcylindricum denique late depressum c. 12 mm longum 
atroviride; squamae sublatiusculae obtusiusculae, exteriores sublaxae multo 
breviores angustioresque, interiores in margine obscure virides, omnes 
pilis dispersis ad 1,5 mm longis, glandulis mediocriter numerosis sae- 
pissime minutis et basin versus floceis parum numerosis obsitae, Pedun- 
culi graciles apice leviter incrassati, dense floccosi v. canotomentosi, 
pilis dispersis basi obscuris ad 2,5 mm longis et glandulis subsparsis 
minutis obtecti, Caulomata superne subpilosa, 3—4 mm, et dense floc- 
cosa. Bracteae 2—3 lineares obsure virides. Flores lutei, ligulae apice 
glabrae, stylus concolor, achaenia atro-brunnea. 
Prov. Terek: In cacumine m. Beschtau pr. Pjatigorsk 1440 m, in 
consortio H. wmbellati, beschtavici et simplicicaulis. 
Habitus H. umbellati var. submonticolae. Verosimiliter inter hanc et 
subspeciem simplicicaule intermedia vel olim hybrida. Ab H. dacico typico 
praecipue foliis angustioribus differt. 
Variat: 8) subpilosum, folia supra pilis ad 2—4 mm longis subpilosa, in 
margine sat dense ciliata, subtus subpilosa, in nervo dorsali praesertim 
basin versus densius longiusque pilosa. Caulis inter folia media dense 
pilosa. — In m. Beschtau 640 m. 
Huc pertinet etiam Hieracium microtum Boiss. = sparsiflorum > um- 
bellatum Zahn (in Dagestania: supra Ratlu in pineto a cl. Ruprecht! 
lectum), capitulis minoribus (9--10 mm), H. sparsiflori prorsus similibus, 
stylis denique nigris. 
36. Hieracium Litwinowianum Zahn, nov. spec. 
Aphyllopodum. Caulis c. 40 cm altus crassiusculus substriatus ob- 
scure viridis v. praesertim basin versus + violaceus, infra medium pilis 
rigidiusculis curvatis brevibus in basi ipsa subnumerosis obsitus, fere 
usque ad basin subfloccosus, eglandulosus, sublignosus. Folia caulina
