128 MR. C. C. LACAITA ON TWO 
.13 by ? mm. The only real discrepancy is in the * margine revolutis ” of 
Velenovsky, and he was not deseribing Athos specimens. 
(4) Bentham says * suffrutex semipedalis," but of the pieces on Sibthorp’s 
sheet two measure just 8 inches (20:5 cm.) ; Pichler’s and Coumary's plants 
10-22 inches without the base of the stem. Grisebach places T. heterotrichus 
among his *frutieuli erecti vel ascendentes, rhizomate descendente," dis- 
tinguished from * suffrutices, ramis primariis demum decumbentibus, flori- 
feris adscendentibus." Indeed, the whole plant is obviously a much taller 
and more erect plant than T. Chaubardi or any of our forms of T. ovatus 
(T. Chamedrys). 
(5) The rather stiffly hairy calyx is set, as in so many Mediterranean 
thymes, with beautiful ruby glands, some of which also stud the outside of 
the corolla. Hitherto no one seents to have noticed that a certain number 
of similar glands are found on the upper part of the stem itself. These are 
conspicuous in Pichler’s and Coumary's plants, but are very difficult to see 
on Sibthorp’s. However, I have detected a few. 
The Thymus to which this species seems more nearly related by its 
remarkably small calyx and corolla is T. montanus, Waldst. & Kit., as figured 
in Pl. Rar. Hung. t. 71, and represented Fl. Exsicc. Austr. Hung. no. 2142 
and by the Slavonian specimens from Mt. Veliky Gradac, distributed by Dr. 
S. Kupeok. his, however, has the leaves of. T. ovatus (=T. Chamadrys), 
glabrous stems and ealyces hardly, if at all, glandular. But it would . 
require a complete study of the thymes of the Balkan peninsula to establish 
the precise affinities and the limits of distribution of Thymus Sibthorpit. 
(2) CREPIS RUTILANS, sp. nov., e Sect. Barkhausia, Radix verticalis, nescio 
an biennis seu annua. Caulis solitarius, erectus, 85-65 cm. altus, villis albis, 
mollibus, tenuibus et pilis robustioribus rubro-purpureis, basi dilatato in- 
sidentibus, preeditus. Folia pilosa, mollia, inferiora in exemplari (A) 
simplicia, leviter repando-dentata, dentibus retrorsis, in (B) runcinato- 
pinnatopartita segmento terminali maximo ; caulina media amplexicaulia, 
oblonga, superiora e basi sagittata lanceolata. Pedunculi etiam ante 
anthesin erecti, sub anthesi breves (1-2:5 cm.), in fructu elongati (1:5-3 em.), 
pilis rubro-purpureis aliisque pallidis brevioribus, nonnullis glanduliferis, 
crebre vestiti. Capitula mediocria, eis C. setose eequalia, illis. C. fatide 
dimidio minora. Involueri phylla externa subadpressa, pilis longis rubro- 
purpureis barbata, interiora sparse cano-tomentosa, dorso etiam in fructu vix 
indurato. Achenia tenuia, omnia in rostrum tenuissimum, ipsis vix brevius, 
abeuntia, pappo niveo involücrum vix superante. 
Differt ab omnibus C. fætidæ varietatibus caule non a medio ramoso, 
panicula corymbosa, alabastris erectis, capitulis minoribus, acheniis cum 
pappo duplo brevioribus.
