papillae. Above the constricted area there are no stomata, 

 nor glands, nor papillate swellings. On the inner surface, the 

 distribution of stomata and glands is practically as above, 

 excepting for the presence of several rather long, fine hairs 

 along the median veins of the constricted area. S. purpurea 

 has petals 4-5 cm. long. The proximal portion of the petal is 

 not wider than the distal section. The constriction between 

 them is very shallow (fig. 29, a), and the sides of the petals 

 scarcely rolled back. The distal portion of the petal is ovate. 

 In color, the petal is crimson without, much lighter within. 

 The base of the petal is pale greenish or whitish. Glands are 

 numerous over the central part of the petal, back as far as the 

 constriction. In 5. Catesbaei the petals are intermediate in 

 length, 5-6 cm. long. The upper portion is slightly more 

 rounded than in S. purpurea; the constriction is more pro- 

 nounced than in the latter (fig. 29, c). The color is inter- 

 mediate. Above, the petal is white. The lower portion of 

 the petal is rose-pink. That is, the purple-pink dissolved 

 pigment in 5. purpurea is diluted and weakened by the chromo- 

 plasts from 5. flava. Glands are present at the tip, and along 

 the median veins only to the constricted areas. 



The stamens in all are variable in number — from 50-60. 

 They are formed by the breaking up of each of the 10 staminal 

 primordia into 5-8 lesser primordia. 



Pistil. The umbrelloid style is provided with numerous long 

 hairs, pointing generally toward the 5 stigmatic knobs. The 

 stigmatic hairs are short and stout, usually bent with the tip 

 often swollen. 



In S. flava, the stigmatic hairs are short and but slightly 

 curved, with swollen tip. 



In S. purpurea, the hairs are longer, and more decidedly 

 curved. The hairs of S. Catesbaei are longer than those of 

 >S. flava, yet not so long as those of 5. purpurea. The stylar 

 hairs are abundant and long in S. flava. In S. purpurea the 

 hairs are of about the same length, sparse within, absent with- 

 out. In S. Catesbaei, however, the hairs are very short. 



S. flava, S. Drummondii, S. Moorei 



In S. Drummondii, the flowers are pendulous, as in S. flava, 

 are of about the same size, 6-7 cm. long, and 14 cm. across their 

 greatest width. The bracts are red. S. Moorei has usually,
