j^gg List of Spoiitaueous Vascular Plants, hitherto observed in Cyprus. 



Already Boenmullee has corrected Boissiee's mistake in referring the plant collected at Yalussa 

 by SiNTENis and Rifio (SR 296) to C. pumilio L.'), a species which is only known to occur in Northern 

 Africa (Marmarica, Eg-ypt) and Syria. 



The two species may be quite easily disting'uished by characters from the pappus-rays and the 

 involucral scales : 



('. pumilio- C. cretica, 



Phj'llis iiivolucri internuMliis in .s]iiiifi valiilå. .5 — Kmiii. I'liyllis involucri intermediis in spina tcnui, 1—3 mm.

paleolis seriei intimi subnlatis, inteaerrimis, glaberrimis. C. immilione duplo longioribus; paleolis seriei iutimi 



li nea ri -lane eolatis, pi an is, apire acutis vol olitiisis, 

 p a p i 1 1 s i s vel s u h f i m b r i a t i s. 



The characters obtained from the shape of the leaves are of much less value for the distinction 

 of the two species, because they are subject to great variations in both. In Syria Boenmullee has observed 

 a series of forms of C. immilio witli the leaves varying from pinnate to entire; in Cyprus exactly the 

 same is the case with C. erotica. 



Post has |in Mém. Herb. Boiss. no. is, 1)6 (19U())| described a variety, alpiiiu, from Troodos: 

 "Capitulis oblongis, solitariis typo miuoribus, foliis fere omnibus integris." These characters arc not, how- 

 ever, constant enough to entitle the alpine form to be a distinct variety; quite similar forms arc often 

 met with on the sea-shores of Cyprus. 



Various opinions have been pronounced as to the identity of Sibthorp's Cymtra m-Kulis (Prodr. 11, 

 158), which he indicates to grow in Cyprus. It cannot be identical with C. acaulis L. (now called 

 Centaurea Chamaerhaponticum Ball), as supposed by Decandolle (Prodr. VI, 664) and Kotschy (Cypern, 

 2-t8); this is a plant occurring only in Northwestern Africa. Boissieu (F1. orient. Ill, 592) refers it to 

 Bluqwnticiini 2i>isiUum Boiss. (= Cent, pi/gmaea Benth. et Hook.), but this also is a species otherwise unknown 

 in Cyprus. It seems much more probable, that Cent, crctlca Nyman is meant, because this is a plant of 

 very similar external habit, and is in Cyprus too common and conspicuous a species to escape the attention 

 of so exact an investigator as Sibthoep. 



Sandy sea-shores, very frequent. Hag. Napa (JH 6), Salamis (JH 456). Also frequent in the 

 pine-forests on Troodos above Pi-odromo, ca. 1600 ni. above the sea (Post, JH 958). 



C. cyanoides Berggr. et Wahlenli. in Isis, V. L'l (I8il8); Boiss. Fl. orient. IH, mh et Suppl. :3l:j. 

 Fields near Kyrenia (SR 614!). 



C. acicularif, Sihth. et Smith, Prodr. II, -MH (1813); Kl. (iraec. X, 8, tab. »11 : Boiss. Fl. <irient. 111. l>77: Kotschy, 

 L'ypern, 244. 



A little known species, not collected after SiBTtioKi-'.s time, by him indicated to grow in Cyprus 

 and Leros. Closely related with this plant, and probably to be registrated as a subspecies of it, is C. 

 exscapa Urv. (= C. acicularis p UrriUci Boiss.), growing in Cos and Leros. 



C. solstitialis L. Sp. pi. ed. 1, HIT (175:3): Boiss. Fl. orient. Ill, 685; Kotschy, l'ypern, 244. 

 Fields, common in lower regions. Limassol (Michaelides!).

 Fields, waste places, common. Pentadaktylos (SR 543!). Already mentioned by Claeke.
