Rather common in the territory explored, partly together with the preceding one 

 at Ust Abakansk, Ust Kamuishto, and Askys. At Ust Kamuishto, I have collected a series 

 of forms that seemed to constitute transitions to the preceding one, and probably being 

 of a hybrid nature (Hausknecht in Mitt. Geogr. Ges. Thiir. II (1884) p. 217). 



Distribution: Europe, central Asia to China, north-western Africa, North America. 



In the material brought home there may, besides the typical form, (var. typicus 

 BucHENAU in Engl. Jahrb. XII (1890) p. 188) be distinctly separated the following 2 types, 

 between which, however, there are to be found numerous intermediate forms. 



subspec. atrifuscus (Rupr.) Trautv. in Bull. Soc. Nat. Moscou (1867) p. 110. Juncus 

 bulbosus L. var. atrofuscus Regel in Bull. Soc. Nat. Moscou (1868) p. 272. 



This subspecies, which is especially characterized by its loose, generally rather 

 long-stalked flowers, and nearly black perianth leaves, I have collected on the Abakan 

 Steppe, near Askys. In full flower in the middle of June. 



Distribution: Subarctic regions, and the salt steppes of the interior of Asia. 



subspec. salsuginosus (Turczan.) Buchenau in Engl. Jahrb. XII (1890) p. 189. Juncus 

 salsuginosUs Turczan. Cat. Baical. no. 1164; Ledeb. Fl. Ross. IV, p. 230; Turczan. Fl. 

 BaicaL-Dahur. (1855, II) p. 304, no. 1194; KptM. $.i. Am. VI (1912) p. 1409. 



This subspecies has rather dense flowers, partlj' congested in a head, whereby this 

 form, in point of external habitus, is apt to be confounded with Juncus alpinus. Occurs 

 in moist grass-field in depressions on the Abakan Steppe, here and there together with 

 the preceding one. 



Distribution: The steppe area of central Asia. 



Juncus filiformis L. Spec. PI. ed. II (1762) p. 465; Buchenau, Juncaceae in Engl. 

 Pflanzenr. H. 25 (IV, 36, 1906) p. 127; Ledeb. Fl. Alt. 11, p. 46; Turczan. Cat. Baical. no.. 

 1162; Ledeb. Fl. Ross. IV, p. 223; Turzan. Fl. Baical.-Dahur. (1855, II) p. 302, no. 

 1190; Kpwji. ^JL. Ajit. VI (1912) p. 1410. 



Not unfrequently to be found at Kushabar, near Ust Algiac, on the Sisti-kem, and 

 at Ust Tara-kem, in moist, grassy places. With young flowers in the middle of July. 



The specimens collected are large and vigorous, to 0,5 m. high, few-flowered, to 

 7-flowered (f. typicus Krylow, <D.t. Axr. VI (1912) p. 1411). 



Distribution: Europe, except the more southern portions, south-western Asia, Sibe- 

 ria, northern Mongolia, Sakhalin, North and South America, Greenland.

 1169; Ledeb. Fl. Ross. IV, p. 233; Turczan. Fl. Baical.-Dahur. (1855, II) p. 306, no. 1197; 

 KpBiji. $ji. Ajlt. VI (1912) p. 1415. 



In the Altaian, above the tree limit, in moist, grassy places. In full flower at the 

 end of July.
