 The photograph on Plate 12 is of a complete specimen that had been lowered 

 down from the cliff.

Masatierra: Portezuelo de Villagra, c. 600 m, two specimens at the foot 

 of the crest west of the pass (past fl. 24 /i2 16, no. 188). 



Described from a fragment without flowers or fruit, collected by me in 

 1908, as far as I can understand taken from one of the two bushes seen in 1917. 

 They bore flower heads, but petals and stamens were gone. No ripe fruits 

 were encountered. A complete description is given below. 



Arbuscula glaberrima 0,75 m saltern alta, erecta, pseudodichotome ramosa, 

 ramis 5 — 10 mm crassis, junioribus creberrime annulatis. Folia ad apices ramo- 

 rum confertissime rosulata, firma et crassiuscula, basi tenuiora subamplexicaulia, 

 nervis perplurimis parallelis percursa, nervo centrali magis conspicuo et in pagina 

 inferiore leviter incrassato, linearia, subspathulata, acuta, margine in parte 

 dimidia vel tertia superiore serratodentata dentibus mitibus utroque latere 5— 9 

 (plerumque 6 vel 7), 6—12,3 cm longa et 11 — 25 mm lata, basi 9 — 12 mm. 

 Inflorescentia terminalis monocephala, scapo 5 — 6 cm longo et 3 mm crasso 

 superne cavo. Involucrum circ. 18 phyllum phyllis longissime triangulatis acutis 

 basi incrassatis, margine inferne scariosis, supra colore fuscoviridi in violaceum 

 spectante, subtus viridibus, ad 20 mm longis et 5 mm latis. Capitulum circ. 

 17 mm altum et 20 latum, viridi-violascens. Receptaculum cavum caverna 

 6—9 mm alta et 8 — 12 mm diam. Bracteae lineari-subspathulatae, apice trun- 

 cato-rotundatae, basi incrassatae, 5 mm longae et 1,5 — 2 latae, hyalino-albidae, 

 apice violaceae. Flores confertissimi omnes jam deflorati, 6 mm longi et 3 mm 

 diam. Sepala ovata, rotundato-acutata, margine scariosa, viridia, apice viola- 

 scentia, 2,5 — 3 mm longa et 1,5 — 1,7 mm lata. Petala . . . Stamina . . . Stylo- 

 podium crateriforme obscure viride. Styli 4,5 — 5 mm longi virides. Mericarpium 

 immaturum 3,5 mm longum, viride, sectione triangulare, apice circumcirca appen- 

 diculatum, dorso et margine appendiculis humilioribus ornatum. 



T am strongly inclined to regard this as a bastard between E. btipleuroid.es 

 and E. inaccessum. This idea did not occur to me when describing the species, 

 as one of the supposed parents was unknown at that time. In most characters 

 it is intermediate between the two. The cortex is more as in E. inaccessum, 

 but the internodes sometimes slightly longer. The leaves are exactly inter- 

 mediate in shape and size (see fig. 21), and so are the marginal teeth in shape 

 and number; they are not pungent. The midrib is more conspicuous than in 

 E. inaccessum, where all the principal veins are of the same strength, but less 

 prominent than in E. bupleuroides. The scape and receptacle are hollow as in 

 the former. The involucral leaves are intermediate in shape, size and number, 

 being green in E. bupleuroides. The head stands between the two in shape 

 and size and so do the sepals. The fruit is more like that in E. bupleuroides. 

 No ripe seeds were found. In anatomical structure the fruit takes an inter- 

 mediate position. Both the supposed parents grow close to the place where 

 E. fernandezianum was found, and its great scarcity speaks rather in favour of
