 what hairy, pinna) dccurrcnt ol)long ratlier obtuse remote

 fronds small rather tender ]jinnated, pinna) distichous sub- 

 vertical ])innatifid, segments linear simple or bifid and as 

 well as the supraaxillary solitary subcompressed involucres 

 spinuloso-serrate the valves semiorbicular, the very short cu- 

 neate base sunk, rachis winged above. Sm. Fl.Brit.p. 1141.

 "Il.unilaterale? Willd.'" ( according to a specimen from Mar- 

 tins^ it is this species J. — fi. frond elongated, pinnae more dis- 

 tant and more rigid. H. cupressiforme, Lab. Nov. Holl. p.

Hah. Europe, northern or alpine or suhalpine districts. Azores, Gtith- 

 nic. Madeira. Cape of Good Hope. Mauritius, Carmichael. Chili, 

 lieechey ^c. \»\(!iW\a., Bridges n. 798, Poeppiy, D'Urvillc. Brazil, -/»/ar- 

 tius. — i3. Tasmania, New Zealand, Cape of Good Hope. Orphan Mountains, 

 Brazil, Gardner, n. 212. — Mr. Brown rightly determines the //. cupressi- 

 forme of Lahillardiere to he our H. Tunbrid(/mse, or hut a trifling variety. 

 The species indeed seems to be an inhabitant of various parts of the 

 globe, in the old and new world, in the northern and southern hemi- 

 sphere. In the Organ-mountain specimens, and in some, but not all, from 

 Tasmania, the involucres are nearly entire, and scarcely distinguishable 

 from those of H. Wilsoni. Poeppig refers our H. T^inbridgense from Chili 

 to his new species, //. asperulum, but his asperulum quite accords with the 

 European Tunbridgense. 



30. H. Wilsoni, Hook. ; fronds rigid pinnate, pinngc re- 

 curved subunilateral wedge-shaped in circumscription pin- 

 natifid, the segments linear undivided or bifid spinuloso- 

 serrate, involucres supraaxillary substipitate solitary ovate 

 inflated entire the rachis generally free to the base. Hook, 

 in Brit. Flor. Wils. in E. Bot. Snppl. t. 2686, ic.vcellent).
