shores of Asia, the New Siberian islands and the Tschukt- 

 scher-land. The var. altaica (Bunge) is found in the same 

 countries; only from West Greenland I have not seen any 

 specimen. Outside the Arctic Regions D. Fladnizensis is 

 found in the Rocky Mountains, northern Scandinavia, the 

 Alps, Siberia, Ural-, Altai-, Baikal Mountains and Himalaya. 



Dr aba hirta L. 



The leaves are lanceolate with few teeth or entire, 

 densely hairy with coarse branched hairs, rarely a little 

 ciliate at the base. The stems are generally strong, c. 20 ctm. 

 high, densely hairy, with one to four ovate, sometimes clasping 

 leaves, with 1—3 teeth on both sides. Inflorescence elon- 

 gated, pods often a little twisted, hairy or glabrous and with 

 a short style (Fig. 15). Small forms have often been confoun- 

 ded with D. Fladnizensis, D. alpina etc. 



D. rupestris R. Brown in Aiton Hort. Kew. ed. 2, often con- 

 sidered a separate species, is only a small form of D. hirta 

 (such as Fig. 16 a), about which I have convinced myself by 

 seeing original specimens in the herbarium of the British Museum. 



D. scandinavica Lindbl. 1. c, D. laxa Lindbl. and D. tri- 

 chella Fr. apud Lindbl. 1. c. are also only small condensed 

 forms of 1). hirta (Fig. 16). 



D. corymbosa Lge. Gonsp. Fl. Groenl. and Flora Danica 

 t. 2418 is, as above mentioned, a small form of D. hirta. This 

 also is the case (at all events partly) with D. corymbosa in 

 Reichardt: Flora der Insel Jan Mayen, Nathorst: Spetsbergens 

 käriväxter and Th. Fries: Beeren islands Vegetation. 



D. subamplexicaule G. A. W. Mey., D. hirta f. subamplexi- 

 caale Kjellm. (Vega Expd.), is a form with broadly clasping 

 leaves on the stem. 



D. stenoloba Ledeb., D. hirta v. siliquosa Ghamisso & 

 Schlechtend. in Linnæa I, is a form with linear-lanceolate 

 pods. D. stenoloba of American authors is generally not this 

 plant but belongs to the section Drabella.
