876 C. SKOTTSBERG 



m. A 30 — 40 cm tall sedge, quite conspicuous thanks to the long, dark brown, 

 pendulous 2 spikes. In fruit in February. 



Luzula masafuerana Skottsb. Endemic in the highland of Masafuera, iioo — 

 1400 m, rare. Robust and densely tufted, with culms to 50 cm long. With ripe 

 seeds in February. 



Juncus procerus E. Mey. (see p. 775). Masatierra, on barren slopes near the 

 sea and on the elevated ridges (PI. 90: 2), west to Bahia Chupones and Vaqueria; 

 rare. Largest of the rushes in Juan Fernandez, to i m tall. With flowers in 

 January and fruits in April. 



Jwicus iuibricatus Laharpe. Masatierra, grassy slopes near the sea, scarce. 

 With flowers and fruits Dec. — ^Jan. 



Juncus dombeyajius C. Gay. Scattered in the grassland of Masatierra (J. 

 microcephalus Kunth according to Johow; see p. 112), observed by us in a single 

 locality. With flowers and fruits in January. The remaining 2 species, J. capil- 

 laceus Lam. and plamfolius R. Br., were found by us for the first time and only 

 near the settlement in Masatierra; they are, I presume, recent arrivals. 



Lihertia forniosa Graham. Iridaceae. Both islands, in open situations on 

 grass-covered, stony slopes and ridges from about 200 to 600 m on Masatierra 

 and from the coast to about 1400 m on Masafuera. One of the most conspicuous 

 herbs, forming large, bright green tufts. Leaves narrow, sword-shaped, equitant, 

 flowers white. Buds from the lower axils, tightly embraced by the persistent 

 leaf bases (Fig. 28 g — i). With flowers Nov. — ^Jan. and fruits in February. 



Seeds sown 25.7. 1918 germinated in September and the plants flowered end of 

 April 1920. Long known in cultivation, originating from Chile. 



Peperomia herteroana Miq. Piperaceae. Endemic. Not uncommon in the wet, 

 shady montane forests of Masatierra above 400 m; in Masafuera on the moist 

 walls in the deep canyons, apparently rare and not seen with flowers. A succulent 

 species with a thick rhizome and as much as 50 or 60 cm tall, vegetative-floral 

 shoots; robust stems to 12 mm thick. Leaves short-lived, accumulated toward the 

 end of the shoot (PI. 79: 2). Gemmae in the soil surface with apex covered by redu- 

 ced, scale-like leaves (Fig. 28 c, d), resembling the winter-buds of a certain type 

 of hemicryptophyte, but the flowering shoots continue to grow and to produce 

 new leaves and spikes at any season — a kind of combination of a nanophanero- 

 phyte and a hemicryptophyte. For particulars, see Skottsb. 21, 22, with illu- 

 strations. 



Peperomia margaritifera Bert, ex Hook. Endemic on Masatierra, in wet 

 soil in two of the well-watered valleys (p. 114), rare. Habit of the former, but 

 much less succulent. Rhizome short, incrassate, shoots to 40 cm long, with num- 

 erous small gemmae (as many as 9 observed) in a circle immediately under the 

 soil surface, beginning with a few short internodes with minute, scalelike leaves; 

 a prolonged internode follows, ending in a naked apical bud (Fig. 28 e, f). In 

 April the vegetative-floral shoots continued to form new spikes and leaves, and 

 very likely growth goes on during the winter as in the former; see also Skottsb. 22.
