150 CARL SKOTTSBERG 



600—650 m, common together with the supposed parents (fr. 8 /i2 16, no. 80, 

 13 /i 17, no. 80 a, b); Pto Ingles, central ridge, 575 m (fr. 19 /i 17, no. 323); 

 Q. Villagra, c. 500 m (fr. 10 /i 17, no. 1218). 



The following notes on the leaves and scales of these specimens will give 

 an idea of the range of variation. 



No. 62+. Fig. 16 c. — Adult leaves all peltate, very rugose below, larger 

 tubercles on veins and petiole few, small; blade almost smooth above. Scales 

 linear — triangular, slightly pilose on back, reddish brown; margins short lacerate. 

 Scape glabrous, bracts mostly gone, remaining ones ± intermediate in shape. 



No. i2jo. Fig. 16 d. — Leaves peltate, petiole aculeate and pilose, nerves 

 with few tubercles, lower surface rugulose, upper very rough, thus leaves like 

 those of peltata, but the lobes more blunt. Scales entire to short lacerate, 

 ovate to linear-triangulate, reddish brown, pilose on back. 



No. 383. Fig. 16 e. — Leaves only slightly peltate, otherwise as in pel- 

 tata; scales narrow linear to triangular, reddish brown, shortly lacerate, densely 

 pilose on back. Scape pilose, bracts as in peltata. Spike less dense than in 

 this. Budding parts more slimy than in peltata. 



No. 323. Fig. 16 f. — Leaves not peltate, with acute, serrate lobes, pil- 

 ose on the nerves below, with few and low tubercles. Scales ovate — triangulate, 

 acute, entire or slightly dentate, brownish green with reddish centre, a little 

 pilose on back. Scape glabrous; no intact bracts left. 



No. 80 a. Fig. 16 g. — Leaves slightly or incompletely peltate, slightly 

 rugose below and almost smooth above, petiole strongly aculeate. Scales ovate — 

 triangulate, acute, entire or dentate, greenish brown with reddish centre, glabrous. 

 Scape glabrous, bracts as in bracteata. 



No. 80 b. — Like the former, but leaves peltate and nearly smooth on 

 both sides. Scales narrower, rarely dentate, slightly pilose on back. Bracts a 

 little narrower. 



No. 80. Fig. 16 h. — Leaves peltate, smooth, slightly pilose on the nerves; 

 petiole with scattered low emergences. Scales greenish brown with reddish 

 centre, broad linear — triangular, acute, entire or lacerate in the upper half, almost 

 glabrous. Scape nearly glabrous, bracts of peltata type. 



No. 1218. Fig. 16 i. — Leaves not peltate, nearly smooth above, slightly 

 rugose and aculeate below. Scales green, ovate — triangular, acute, entire or 

 lacerate, a little pilose on back. Scape glabrous. No intact bracts left. 



82. G. Masafuerae Skottsb. — Stud. 14, Fig. 3; Taf. 3 — 4. 



Masafuera: known before only from Q. de las Casas, now found in many 

 places and not at all confined to the canyons, but quite common higher up on 

 the mountain slopes or in the shallow ravines in the alpine region. ■ — Along the 

 road to Las Chozas, open spaces in the forest belt; in the higher treeless tracts 

 between 700 and 1100 m, extensive patches in some places; Q. de las Casas, 

 between stones by the stream and on the rock walls of the canyon (unr.-fr. 

 23 /2 17. no. 400); Q. de las Vacas, reaching farther down owing to the greater 

 supply of water; Q. del Blindado, in the forest, 440 m; Q. Angosta, by the 

 waterfall; Q. de la Loberia, 280 m, in open forest. Also in the alpine region:
