204 CARL SKOTTSBERG 



inflorescence is rather large, more condensed, with numerous heads; these are 

 smaller than in the former and the involucre much more urceolate. The open 

 head in full bloom measures 3,5 cm across; it only contains about 50 florets. 

 The corolla attains a length of 40 — 42 mm; the whitish tube is soft papillose 

 in the middle part, the deep orange coloured ligule is 3—3,5 mm across. Anthers 

 dark lilac brown with tails considerably longer than the gland of the filament. 

 Style yellowish white below, upwards covered with brown papillae, also on the 

 back and sides of the branches, while their upper surface is clothed with low, 

 light yellow stigma papillae. Branches of the style 4,5 mm long. Achenes 

 larger than in any other species, 7 or even 8 mm, brown, thick, with longitudinal 

 furrows; marginal ones curved with distinct lateral wings and a ventral keel, 

 the others with thick dorsal and ventral wings. Embryo very large, 5—6 mm 

 long, with entire, orbicular cotyledons. Pappus turning dark rufous with age. 

 Area of distribution: Endemic in Masatierra.

Morro Vinillo, a small rock off the south coast of Masatierra (P. Arre- 

 DONDO a. o.); cultivated specimens, raised from seeds gathered in Vinillo seen 

 in some of the gardens in Masatierra (plate 19). 



Santa Clara: Crevices in the coast cliffs of the main island, and on 

 Morro de los Alelies (fl.-fr. 26 /i 17, no. 342). Also observed by Johow. 



Very near D. tnarginata, but distinct. The leaves are thicker, with smooth 

 edge, the heads larger with twice as many flowers, the anthers and style yellow, 

 the tails of the anthers shorter. The achenes are very different and the embryo 

 considerably smaller. These achenes are mature, for I have raised numerous 

 specimens from the portion collected by me in Santa Clara as well as from 

 others of absolutely identical appearance gathered in the garden of ARREDONDO, 

 who introduced the species from Morro Vinillo. My plants are all of the same
