CRITICAL NOTES ON SOME SPECIES OF CERASTIUM. 385 



foliis angustioribus longioribus et latioribus magisqiie spathulatis 

 ac turn capsulis subbrevioribus. Semina dorso leviter sulcata, 

 faciebus leviter depressa. 



The specimens I examined were Liebmann's PI. Mexic. n. 1, 

 collected in the Chinantla district of prov. of Puebla in May, 1841. 

 The type-specimens were collected by Schiede at San Salvador, 

 near Jalapa, in the prov. of Vera Cruz. Liebmann's specimens are 

 20-22 centim. high, and a medium-sized capsule contained thirty- 

 five seeds. By Grenier (Monogr. Cerast. 83) placed among the 

 doubtful and obscure species. In the original description Schlech- 

 tendal says: " habitu ad C. vuh/atum (sen triviale) accedit sed folia 

 longiora angustiora, inflorescentia laxior, attamen ut jam prius 

 diximus affine quoque C. 7iutanti Americse septentrionalis." This 

 earlier reference to the plant is in Linniiea, v. 233 (1830). Specimens 

 were subsequently distributed under the name of C. mexicanum by 

 Schaffner, Coll. PI. Mexic. n. 301. 



25. C. Apuanum Pari, in Nuov. Giorn. Bot. vii. 69 (1875). 

 Parlatore says : " immerito ab auctoribus cum C. alpino Linn, quod 

 ab Apenninis omnino exul, et C. arvensi Linn., a quibus satis 

 differt, confusum." By Nyman the plant is placed under 0. Thomasii. 



Syn. C. (ilphiwn Bertol. Fl. Alp. Apuan. in Amoen. Ital. 368, et 

 Fl. Italica, iv. 762 (as to the plant from the Apuan Alps). 



Hab. Italy ; several localities in the Apuan Alps, in the prov. 

 of Massa-Carrara. 



26. C. ARABicuM Fisch. & Mey. ex Heynh. Nomencl. Bot. ii. 133 

 (1840). I can find nothing about this plant. It is mentioned 

 neither by Fresenius (Beitr. fl. ^Egypt. Arab.) nor by Deflers 

 (Voyage au Yemen). From the cliaracter of the work in which it 

 occurs, it may be only a garden form. 



27. C. Arabidis E. Mey. ex Fenzl in Ann. Wien. Mus. i. 340 

 (1836); Harv. & Sond. Fl. Capensis, i. 130 (1858). A species 

 founded on Drege's specimens n. 3557, collected at 2200-2400 

 metres on the Witte-berg, in Cape Colony. So named by Meyer 

 from its lanceolate leaves resembling those of Arabis hirsuta. 

 Sender describes a ^^ \SiY. glitti7iosum" from Tambu-land, which is 

 scarcely more than a form with somewhat weaker stems covered 

 with short glandular hairs, instead of with long hairs towards the 

 base as in the type. The species is also recorded from Queenstown 

 District (Cole, 1860, Cooper, n. 393); Mt. Currie, in Griqualand 

 East, at 1600 metres [Tyson, 1883, n. 1365); and Faku's territory 

 {Sutherland, 1864). All these specimens match those collected by 

 Drege. 



28. C. Araraticum Eupr. Fl. Caucasi, 234 (1869) = C. alpinum 

 var. Araraticum Williams. — Ruprecht says that this plant is nearest 

 C. gtiaphalodes, from which it differs in " foliis turionum radicalium 

 non fasciculiferis, apice haud congestis subrosulatis, oblongo- 

 linearibus, similibus caulinis, nee rotundato-spathulatis hetero- 

 morphis, sepalis ssepe minoribus, vix ultra 6 mm., petalis calyce 

 duplo majoribus." In the seeds, however, the nucellus is closely 

 invested with the testa, as in all forms of C, alpinum. In Moritz's
