A morphologically very closely related species is Convolvulus coch- 
learis Griseb., originally described (Spic. FI. Rumel. 2, 76, 1844) 
from Eastern Anatolia (legit Donietti). A type-specimen has not 
been seen by the writer but there seems no doubt from the description 
that the Greek plants referred to this species by Boissier (FI. Or. 
4 , 98) and by Halacsy (Consp. FI. Gr. 2, 306) are specifically identical 
with it. The name Convolvulus parnassicus was given by Boissier and 
Orphanides (Diagn. Ser. 2, 3, 125) to the Greek plant, but later this 
name was reduced by Boissier to a synonym of C. cochlearis Griseb. 
While the majority of specimens from Spain of C. nitidus can be 
easily separated from the Anatolian and Greek C.. cochlearis by the 
less compact habit, often longer flowering branches, and larger and 
longer and less spathulate leaves, there is no doubt that the two are 
very similar in morphological characters and are presumably closely 
related phylogenetically. Indeed, part of the material distributed 
under No. 339 Huter, Porta and Rigo, ex itinere hispanico 1870, from 
Mt Dornajo, Sierra Nevada, can scarcely be distinguished from 
Greek specimens of C. cochlearis. In any case the Ali-Botusch plant 
is certainly C. nitidus Boiss. and not C. cochlearis Griseb., whether 
this latter be regarded as a species distinct from the former or as only 
a variety of it. 
Mt Ali-Botusch, which has yielded many interesting plants to 
the researches of Prof. Stoianoff, may be regarded as an outlier to 
the south-west of the great Rhodope massif, itself the home of 
numerous rare species of plants. The specimens of Convolvulus nitidus 
from the mountain and referred to in this note were collected on 
July 10th, 1920, between 1800 and 2000 m. altitude, on limestone 
rocks.
