§ 1. Radiatum; radii corollis elongatis minute tridentatis. (Pleurophyllum verum.)
1. Pleurophyllum speciosum, Hook. fil.; foliis villoso-lanatis, caule superne præcipue pedunculisque dense albo-tomentosis, capitulis radiatis radiis elongatis, receptaculo convexiusculo marginibus 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.
Radix fusiformis, crassa, carnosa. Caulis elongatus, 2-3-pedalis, erectus, simplex, teres, v. obscure angulatus inferne crassus, carnosus, solidus, dense albo-tomentosus, tomento e pilis simplicibus inarticulatis inferne demum deciduo. Folia omnia coriacea et subcarnosa, multinervia, nervis parallelis, integerrimis, villosis, subsericeis, 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 pallidiora; superiora seu caulina gradatim minora; suprema lanceolata obtusa. Racemus terminalis, elongatus, foliosus; folia (seu bracteæ) inferiora flores superantia. Pedunculi crassi, densissime albo-lanati, inferiores interdum compositi 3-4 flores; superiores simplices, patentes, sub-unciam longi. Capitula majuscula, sub 2 unc. lata, speciosa, pulcherrime purpurea, disco intensiore. Involucrum plano hemisphæricum, bi-triseriale; squamis lanceolatis obtusis imbricatis, exterioribus albo-lanatis, interioribus pilosis, 4-6 lin. longis discum subæquantibus. Receptaculum paululum convexum, epaleaceum, alveolatum, alveolarum marginibus (seu parietibus) crassiusculis undulatis. Flores Radii elongati, uniseriales, ligulati, circiter 15; ligula lineari, ½ unc. longa, patente, obscure 3-dentata; tubo brevissimo patentim piloso, pilis mollibus laxis pellucidis articulatis. Stylus cylindraceus bifidus, ramis lineari-oblongis obtusis purpureis planiusculis marginibus incrassatis. Achænium sub 2 lin. longum. Flores Disci circiter 60, intensius purpurei, tubulosi, infundibuliformes; tubo piloso, pilis ut in fl. rad., 5-fido et segmentis recurvis apicibus extus glabris. Antheræ flavæ. Stylus ramis exsertis.
An extremely handsome and 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 prominent stout parallel nerves.
