species growing wild should propose to unite Larraini with Grahamae. JOHOW 

 believes that the size and shape of leaves and flowers undergo so great changes 

 with the external conditions that all differences will be explained in this way. 

 He writes p. 75: »En los terrenos hiimedos i sombrfos se encuentran ejemplares 

 robustos con hojas muy anchas que convienen con la descripcion de la W. 

 Grahamae Hemsl.» but this species is at home on the steep rocky ridges 



and grows exposed to full sunlight; nor is it true that the typical fernandeziana 

 grows »en los lugares menos fertiles». 



All the species are small shrubs with strong, persistent root. The in- 

 florescence is terminal, and the flowering branches die in the autumn, at least 

 the upper, floral part, while innovations are developed from their lower leafy 

 part or from older branches. 



Key to the species formerly united under W. fernandeziana. 



I. Corolla campanulate, white, with narrow contracted lobes; calyx segments 

 narrow, entire; leaves lanceolate or linear-lanceolate, ± acuminate. 



IV. Larraini. 

 II. Corolla ± broad campanulate to funnel-shaped with dark purplish veins; 

 calyx segments dentate. Leaves lanceolate-ovate. 



A. Leaves glabrous or nearly so, narrower toward the base: corolla campa- 

 nulate with ± erect lobes. . - W. fernandeziana. 



B. Leaves pubescent, with broad base, semiamplexicaul; corolla very 

 broad with broad, revolute lobes W. Grahamae.

Masatierra: Bertero 1 no. 1443 ex p.! Scotjler! Douglas! — On the 

 low, dry ridges between the valleys; Pto Frances, Loma Incienso, in shrubberies, 

 360 m; Q. de la Pesca de los Viejos, c. 225 m, in a small ravine (fl. 13 /i2 16, 

 no. 127); C. Salsipuedes, one plant in the height of c. 75 m, several higher 

 up, c. 465 m (beg. fl. V12 16, no. 51 — f. parce pilosa); between Q. Juanango 

 and La Vaqueria, c. 300 m. — A form with spread hairs on the leaves was 

 also collected by SCOULER and DOUGLAS ! 



Suffrutex erectus plerumque glaberrimus, dense ramosus, ramis suberectis 

 sat dense foliosis. Caulis glaber. Folia coriacea, lanceolata vel lineari-lanceo- 

 lata, 20—30 mm longa, 4 — 8 mm lata, basi angustata, apice acuminatim pro- 

 ducta, argute serrata, supra glabra vel secus medianum pilosa, subtus glabra 

 vel rarius pilosiuscula. Flores contracte paniculati. Calyx glaber lobis angustis- 

 simis acutis, integris vel rarissime denticulo glandulaeformi uno vel altero 

 munitis. Corolla ± anguste campanulata, glabra vel secus marginem loborum 

 pilosiuscula, alba, 14 — 15 mm longa, fauce 6 mm diam., expansa ad 15 mm lata, 

 lobis angustis erecto patentibus apice convolutis, 6—7 mm longis et basi 4 mm 



1 Bertero named the plant in honour of a certain Mr. Larrain, who seems to have 

 communicated some species from Juan Fernandez. Tins gentleman is not included in the list 

 of collectors compiled by Johow, and I have not seen herbarium labels with his name.
