Empetruni rubrum Vahl. A single sterile shrub found on the summit of Los 

 Inocentes, Masafuera, about 1500 m above sea-level. 



WaJiloibergia (iraliamae Hemsl. Campanulaceae. Only in the mountains of 

 Masatierra around Hahia Cumberland, also on the Villagra side, among grasses, 

 ferns and shrubs in open situations (PI. 15:2, this vol. no. 7). A straggling, ir- 

 regularly branched shrub, with densely foliated vegetative-floral shoots, the distal 

 part of which dies after fruiting, leaving the woody stem standing. Regenerates 

 from the moderately thick xylopodium. Innovations develop from a few (mostly 

 I or 2) axils below the terminal inflorescence; they were quite small in March. 

 Old branches will reach a length of 50 cm and a thickness of 7 or 8 mm. 

 Flowers Dec— Jan. (1. c. PI. 20: 10). 



Wahlenbergia fernande:;iana (A. DC.) Skottsb. With the former, but occasion- 

 ally descending to near sea-level. A small erect shrub, otherwise as the former. 

 As in this, not all branches belonging to the same generation flower their first 

 summer. P^lowcrs Jan. -March (I.e. PI. 20:9). 



WaJiloibergia Larrabiii (Bert, ex Colla) Skottsb. Masatierra, on dry, exposed 

 ridges from Puerto P^rances to Vaquen'a, rare. Lowest and highest stations observed, 

 75 and 465 m above sea-level. Habit and mode of growth as in the former. With 

 flowers Dec. — Jan. (1. c. PI. 20: 9). 



Erigero7t luteoviridis Skottsb. Endemic in the high country of Masafuera, 1200- 

 1350 m, rare. Differs from E. fniticosus in lacking a distinct main stem; branches 

 from the top of the very long, woody tap-root. Vegetative-floral shoots 20-30 cm 

 long, woody below; innovations from the base with the first internodes long and 

 soon leafless, then shorter to very short and the leaves forming a dense terminal 

 bunch. Buds naked, open. With flowers in Feb. -March and fruit in March. 



Euphrasia forniosissinia Skottsb. Only on Masafuera, not uncommon in the 

 mountain grassland and heath from about 750 to about 1400 m. A peculiar 

 shrubby species, in exceptional cases as much as 70 cm tall, but generally much 

 smaller. The morphology was described on p. 170; see also PI. 15:1. 



Ochagaina elcgans Phil. Bromeliaceae. Pandemic on Masatierra, on the rocky 

 ridges from near sea-level to the high crests, forming extensive patches on the 

 steep, sun-baked cliflf walls (PI. 97), ranging west to the north precipice of Cerro 

 Tres Puntas and the islet of Juanango. Observed once growing epiphytically on 

 a tree in the forest. Prostrate-ascending with very long, trailing, finally lignified 

 branches, densely clothed with curved, thick and glaucous, clasping and pungent 

 leaves. Inflorescence terminal, sessile in the centre of the rosulate leaves, quite 

 showy (Fig. 27 b). Flowers a deep lilac pink; Dec. — Feb. 



Seeds were sown 22.3. 1918 and 27.3. 1919 und seedlings obtained after i — 2 

 months. Of easy cultivation and a vigorous grower, also easily propagated by cuttings. 

 Planted free in a bed in the succulent-house, it stubbornly refused to flower until a 

 potted cutting finally produced an inflorescence in April 1944. It looked like a dwarf 

 tree; the shoot died without ripening the seeds, but regenerated from the stem base 

 (Fig. 27 a).
