 nibus alveolarum crassis carnosis. (Tab. XXII. & XXIII.) 



Hab. Lord Auckland's group and Campbell's Island ; chiefly found upon wet banks and in 

 marshes near the sea, but also ascending to the tops of the mountains in a stunted form.

 demum deciduo. Folia omnia coriacea et subcarnosa, mi ltinervia, nervis parallelis, integerrimis, villosis, sub- 

 sericeis, et pilis fuscis brevibus rigidis moniliformibus subscabrida : radicalia approximata, ovalia, apice obtusa, 

 patentia, subpedalia, 6-8 uncias lata, fusco-viridia, basi villosissima, margine obtusa subrevoluta, subtus pal- 

 lidiora ; superiora seu caulina gradatim minora ; suprema lanceolata obtusa. Kacemus terminalis, elongatus, 

 foliosus ; folia (seu bracteae) inferiora flores superantia. Pedunculi crassi, densissime albo-lanati, inferiores in- 

 terdum compositi 3-4 flores ; superiores simplices, patentes, sub-unciam longi. Capitula majuscula, sub 2 unc. 

 lata, speciosa, pulcherrime purpurea, disco intensiore. Involucrum piano hemisphaericum, bi-triseriale ; squamis 

 lanceolatis obtusis imbricatis, exterioribus albo-lanatis, interioribus pilosis, 4-6 lin. longis discum subaequantibus. 

 Receptuculum paululum convexum, epaleaceum, alveolatum, alveolarum marginibus (seu parietibus) crassiusculis 

 undulatis. Flores Radii elongati, uniseriales, ligulati, circiter 15 ; ligula lineari, \ unc. longa, patente, ob- 

 scure 3-dentata ; tubo brevissimo patentim piloso, pilis inollibus laxis pellucidis articulatis. Stylus cylin- 

 draceus bifidus, ramis lineari-oblongis obtusis purpureis planiusculis marginibus incrassatis. Achcenium sub 

 2 lin. longum. Flokes Disci circiter 60, intensius purpurei, tubulosi, infundibuliformes ; tubo piloso, pilis ut in 

 fl. rad., 5-fido et segmentis recurvis apicibus extus glabris. Antherce Havre. Stylus ramis exsertis. 



An extremely handsome mid showy species with copious large purple flowers, stems 2-3 feet high, and 

 ample radical leaves, resembling those of Plantago major, L., but very much larger, strongly ribbed with pro- 

 minent stout parallel nerves.
