Leaves about 40 cm. long, 18 cm. broad ; petiole 6 cm. or more 

 in length; primary lateral veins, 18 pairs. Floral pedicels nearly 



3 cm. in length, with average transverse diameter of 1*5 mm. at 

 most. The calyx consists of a narrowly funnel-shaped tube over 

 1*5 cm. long, rather more than 1 cm. wide at the mouth, crowned by 

 6 very short, but conspicuously sharp, teeth. The corolla-tube, 

 1*7 cm. or longer, broadens, somewhat, from a diameter of about 



4 mm. at the base to 8 mm. or more at the mouth ; the spreading 

 limb of the corolla measures about 5 cm. in diameter, each of the six 

 lobes being about 2-3 cm. long and 7-10 mm. broad just below the 

 middle. 



LICHENS OF LLANBERIS AND DISTRICT.

The list of lichens given by Mr. Wheldon in the January number 

 of this Journal (pp. 11-15) is a useful one, but, as the author 

 remarks, cannot be regarded as exhaustive. In 1915 I spent a week 

 in the district and last year (shortly after Mr. Wheldon's visit) a 

 fortnight, and I am thus able to add a few notes to the above- 

 mentioned list. 



The inclusion in the list of Lecanora epanora was useful to me, 

 as it brought to my notice that a plant which I overlooked as a 

 sterile form of L. sulphurea was this much rarer plant. Some of the 

 plants in the list, e. g. CJadonia ■uncialis f. ohtusata, C. lepidota f. 

 hypophyUa (which I think descends from C. cervicornis or C. de- 

 q'enera7is\ and the " unexpected " Cerania vermicular is, were recorded 

 from the Snowdon district in this Journal for 1917 in ray papers on
