Folia pleraque 8-10x3"5-5 cm. Pedunculus usque ad 10 cm. 

 long., sed sajpe brevior. Capitula pansa 2"2 x 4 cm. Involucri phylla 

 extima summum 2*5 cm. long., basi 3 mm. lat., superne adusque 



1 mm. angustata ; phylla intermedia 1"5 cm., interiora 1 cm. long. 

 Corollse tubus angustus, 7 X '5 mm., inde subito dilatatus ; lobi 

 lineari-lanceolati, obtusi, 4'5 mm. long. Androecium breviter ex- 

 sertum ; antherse 4'5 mm. long, harum caudis 1"2 mm. long, 

 exemptis. Styli rami clavellati, recurvi, 2 mm. long. Achsenia circa 



2 mm. long. ; jmppi setse dilute straminese, 5-9 mm. long. 



Can be distinguished at a glance by the elongate leaves of the 

 involucre ; the other homogamous species differ in many important 

 respects. E. nutans Benth. is an Eastern rayed species somewhat 

 like E. caudatum in foliage, but in other characters diverse. 



PEDINOPHYLLUM PYEENAICUM (Spruce) Lindb. 

 Br W. H. Pearson, A.L.S. 



In my notes on PedinopliyUiim interriiptum (Hep. Brit. i. 

 p. 271) I expressed the opinion that the \a.Y. pyrenaicnm was "only 

 sportive, as stems which might be described as it are found also on 

 the normal form." Carrington an-ived at this conclusion years ago, 

 and Spruce, who first noticed it, in later years had no great confidence 

 in its specific or varietal value. Some time ago I received from 

 Mr. J. Hunter a rich collection of hepatics from Donegal, amongst 

 them being fine specimens of what I now consider typical F. py- 

 renaicum. 



Lindberg (Not. Sails. F. et F. Fen. For. xiii. p. 36, 1874) con- 

 sidered P. pyrenaicum the most perfect form of P. interrupium 

 (Nees) and reduced the latter to a variety of the former, a view 

 with which I am not able to agree and from which Schiffner also 

 dissents (SchifEn. Hep. Eur. Exsicc. n. 238). Both species are well 

 develoj)ed and are perfect in themselves. The only objection to their 

 being regarded as distinct species is the fact that some forms of 

 P. interruptum approacli P. pyrenaicum in some of tlieir leaves 

 being bidentate. If we knew nothing of intermediate forms and 

 were to compare the usual normal P. interruptum with the Donegal 

 specimens we should have little hesitation in considering them speci- 

 fically distinct. 



P. pyrenaicum is a much larger plant, of a more delicate texture 

 than P. interruptum, having leaves bidentate, rarely tridentate,
