Masatierra: Mrs. Graham! Moseley! — Mountain ridges in the centre 

 of the island. V. Colonial, C. Central, 570 m (fl. 18 /i 17, no. 306); Portezuelo 

 de Villagra, near the pass and abundant in places, 550 — 600 m (fl. 1B /i2 16, 

 no. 1226; fl. 24 /i2 16, no. 1224, f. minus scabra ad praecedentem vergens; fl. 

 10 /i 17, no. 1225, f. laxior); B. Villagra, rock wall at the back of Q. de la Choza, 

 c. 400 m. 



No. 1226 is the most extreme Grahamae that I have seen. Ofthebthers 

 nos. 1224 and 1225 have smaller flowers, measuring only 20 mm across. The 

 possibility of bastards occurring between this and the former should be considered. 



Suffrutex effusus, vage ramosus ramis prostrato-adscendentibus longis sub- 

 flexuosis, pubescenti-setosis foliosissimis. Folia chartacea, sessilia, ovato-lanceo- 

 lata vel ovata, acutiuscula, basi lata fere semiamplexicaulia, dense sed interdum 

 indistincte denticulata, utrinque pubescenti-scabra, subtus in nervis dense pilosa, 

 20 — 35 mm longa et 10 — 16 mm lata. Inflorescentia pseudo-umbellata, foliis 

 triangulato-ovatis instructa, haud multiflora sed ob magnitudine florum valde 

 conspicua. Calyx glaber lobis triangulatis 5 — 7x2—3 mm, inferne dentatis. 

 Corolla late campanulata vel sub fauce leviter constricta fere globoso-campa- 

 nulata, extus puberula, alba, eximie purpureo-venosa, cum lobis 13 — 15 mm 

 longa, expansa ad 25 mm lata, fauce 16 — 17 mm diam., lobis revolutis late 

 triangularibus 7 — 8 mm longis et 8 — 10 mm latis, margine puberulis. Stamina 

 filamentis 3 — 4 mm longis a basi lata valde angustatis; antherae 1,5 — 2 mm 

 longae. Stylus 6,5 — 8 mm, versus apicem incrassatus et cum pagina inferiore 

 stigmatorum setosus.

Masafuera: Germain! Guajardo! — coast cliffs from B. Tolren to Vara- 

 dero and Loberfa, rather common; also in the outer part of the canyons, on 

 rock ledges and in crevices. Only once observed in the highlands, north of 

 Casas, c. 1200 m. Fl.-past fl. Feb. 1917, no. 428. 



f. rosea: A typo differt corolla praecipue basin versus pulchre rosea. — 

 Masafuera: Q. de la Loberfa, one large specimen found among the typical 

 plants (fl. 17 /2 17, no. 489). 



When describing Euphorbia Masafuerae (Bot. Zeit. XIV. 647) Philippi 

 felt sure of the generic position, but later he began to doubt the correctness, 

 as shown by Guajardo's specimen, labelled in PHILlPPl's handwriting: »Eu- 

 phorbia? Masafuerae Ph. (nonue potius Wahlenbergia?) Masafuera 1869 Leybold».
