foliage-leaves, the uppermost in those of scale-leaves (Fig. 21 B). 

 Two bracleoles are seated at the base of each stalk (Fig. 21 A). 

 The flowers are formed during the year previous to that in 

 which they open, and pass the winter protected by foliage or 

 by scale-leaves (Fig. 20 A, B, C). In structure the flowers 

 resemble most closely those of Arctostaphylos Uva-ursi. The 

 corolla is rose-red, roundly-urceolate, and 5-angled and turns 

 its narrow throat downwards iFig. 21Б); the calyx also is rose- 

 coloured. The interior of the 

 corolla is covered with erect, 

 usually somewhat upturned hairs 

 which extend to the margin of 

 thelimb (Fig.2lC,i)); its length 

 is from 4 to 65 mm.; it con- 

 tinues to grow during flowering. 

 The relative length of the 

 different parts of the flower is 

 shewn in Fig. 21 C. The stigma 

 is situated just at or imme- 

 diately within the throat of the

filaments are strongly swollen 

 just above their slender, short bases, and are covered with 

 fairly long hairs along the greater part of their length (Fig. 21 G). 

 Here, as is often the case, they probably serve to retain the 

 honey, secreted by the disk at the base of the ovary (Fig. 21 G). 

 The anthers are covered with small protuberances (Fig. 21 E); 

 they open at the apex by two pores of irregular shape. The 

 two appendages are glabrous and slant upwards and outwards 

 (Fig. 21 C,E,G).
