Endlich wären auch die Beziehungen der Pflanzenwelt zum 

 Menschen (Ethnobotanik) in Betracht zu ziehen, besonders die Ver- 

 änderungen in der Vegetationsdecke unter dem Einfluss des

 This paper contains descriptions of the following new species 

 (the first two already previously described) : Pachystima Myrsiniies 

 (compact bushy habit; branches erect and stiff; leaves decussate, 

 thick and rounded; plant has a yellowish tone); P. macrophyllum 

 (loosely spreading habit; branches somewhat drooping and graceful; 

 swollen petioles; leaves spreading 3 — 5 times as long as broad; bright, 

 almost bluish green tone); P. Schaefferi (same habit as P. macro- 

 pliylliim, but with many more flowers and a strongly bilobed Stigma); 

 P. Kraiitterl (leaves closely ascending, only in one plane; swollen 

 petioles, relatively few flowers, slender style and slightly bilobed 

 Stigma); Arnica Loiiiseana (near A. Lessingü Greene, but much 

 smaller, with slightly glandular-ciliate margins to leaves; usually three 

 heads with uniseriate involucral bracts and pale yellow drooping 

 flowers) ; Hieraciiim Alberiiniim (characterised by the profuse cove- 

 ring of long white hairs); Dryas tomentosa (similar to D. Driim- 

 mondii Richards, but leaves with a thick white tomentum on both 

 surfaces; rather stout, white floccose pubescent petioles and densely 

 glandulär sepals); Raniinculiis apetaliis (closely resembles /?. affinis 

 R. Br. var. validns Gray in its heterophylly, but leaves not succu- 

 lent; no petals, but sepals petaloid). F. E. Fritsch.
