Greece (Sinf. Sf Bornm. It. Tucicmn, 1891, n. 370) ; also from the 

 valle}^ of Lacedaemon, Vourlia, and the Stjmj^halian lake, in the nome 

 of Lacediemon {J. S. Mill, 1842). 



160. C. IMBRTCATUM H. B. et K. Nov. Gen. Sp. Amer. vi. 28 

 (1823). — Rohrbach distinguishes three varieties of this under the 

 species, all represented in Herb. Kevv., in LinncBci, xxxvii. 292, 293 

 (1871-73). They are on three separate sheets. 



a. gemiinum. — Folia dense quadrifariam imbricata ; calyx 4 mm. ; 

 petala et capsula calj^ce longiora. 



Hah. Ecuador: the Andes south of Quito, at 3600-4420 metres, 

 near the summits of Mt. Cotopaxi and Mt. Antisana {Humboldt, 

 Jameso7i). 



(y laxum. — Folia, internodiis pauUum longioribus, parnm remota ; 

 calyx 4 mm. ; petala calycem sequantia ; capsula eum subsuperans. 



The few capsules on the specimen are much shorter than in a. 



Hah. Ecuador : the Andes south of Quito, on Mt. Antisana, — 

 "in the neighbourhood of the farm of Antisana." 



y Maiidoiiiaiium. — Folia imbricata ; calyx 2-2| mm. ; petala et 

 capsula calycem a3(juantia. 



Hah. Bolivia : pro v. Larecaja, near Sorata, Apacheta de Chuchu, 

 at 4200 metres {ILandon PL Aiidium Boliv. 1856, n. 981). 



161. C. INCAXUM Hoffm. Hort. mosq. ann. 1808, n. 805, ex Bieb. 

 Fl. Taur. Cauc. iii. 320 (1819) : = a graiidiflorum. 



162. C. ixcAXUM Ledeb. in Mem. Acad. Petersb. v. 540 (1815) ; 

 et Fl. Altaica, ii. t. 149 (1830) ; Ser. in Cand. Prodr. i. 418, n. 34 

 (1824) ; = (7. arvense var. aiKjusti folium lusus 2, Fenzl in Ledeb. Fl. 

 Kossica, i. 413. Pubescens. Cauliculi stricti confertifolii, inferne 

 pilis elongatis eximie reversis vestiti. Folia caulina majora oblonga 

 vel late linearia, ramorum ac fasciculorum anguste linearia vel 

 lineari-lanceolata basi attenuata. Lobi petalorum ovato-oblongi. 



- Hah. Russia (chiefly Siberia). 



There are four specimens in Herb. Kew. : — (1) Subalpine pastures 

 of Snoktau by the li. Lepsa, prov. of Semirechinsk, south of Lake 

 Balkash {Karel. Sf Kiril., 1841, Enum. pi. Soungar. n. 184 ; 

 (2) PI. exs. Soc. Imp. Nat. Cur. Mosq. n. 1316; (3) Island of 

 Kolguev, in the Arctic Sea {Col. Fielden, 1895); (4) Altai 

 {Kavel ^ Kiril. Enum. pi. Altaic, n. 177). But, according to 

 Fenzl, in Ledeb. Fl. Rossica, i. 782, addend. (1842), this last belongs 

 to C triviale var. leiopetaliom. 



It also occurs in the European province of Cis. Caucasia. 



163. C. IJS'CAXUM Schur, Sertum fl. Transsilv. n. 540 (1853) ; = 

 C. arvense var. incanum Schur, Enum. pi. Transsilv. 123 (1866). 

 Pubescens, pilis brevissimis incano-glandulosis vestitura. Cauliculi 

 geniculati ad medium foliati, superne nudi. Folia minora tenuiter 

 hirsuta. Flores minores multi trichotomo-cymosi, Petala spathu- 

 lata.— PL 2|-3 dcm. 



As Simonkai points out, Enum. fl. Transsilv. [addend.] p. 618 

 (1886), this is not the same as the Siberian plant of Ledebour. 



The descriptions of both are here given, to indicate the points of 

 deviation from the type, — chiefl}^ in the very short hairs and the 

 much smaller leaves in the latter, which is also completely glandular.
