473. HELICHRYSUM. 



binate. , L. linear. Margin revolute. Coiymb 

 subglobose. Phyll. somewbat las. w. 5-7. 

 Dry sand and mariiime rocks, w. 1>. Abr. 

 I refer to this H. nebvodense, Guss., and also 

 stramineum and pendulum ; the two latter of 

 which have the lower L. somewhat wider and 

 lineari-lanceolate. 



5. angustifolium. Tl. oblongo-turbinate. 

 L. linear. Margin revolute. Corymb subglo- 

 bose. Pbyll. closely tiled, w. 5-7. Dry 

 rocky, s. Fr. adr. G. It. 



I include in this microphyllum, of whicli 

 tbe outer phyllaries are woolly, panormitarmm, 

 ccespitosum, littoreum, and italicum, of Guss. 

 H. rupestre is distinguished by DC. as having 

 subglobose flowers ; by Guss., as having them 

 oblong, and at last cylindrical ; yet in his ob- 

 servations on Stcechas, under italicum, he refers 

 to rupestre as having globose flowers. I do 

 not know where to put that or the saxatile of 

 Moris. Some of the plants here grouped to- 

 gether may perhaps be distinct species, but I 

 have found myself unable, after a laborious in- 

 vestigation, to elaborate from the difierent de- 

 scriptions any characters by which it would be 

 possible for the student to identify them.
