closely the glandular surface cells of 5. purpurea. In fact the 

 whole area has much the same character as the corresponding 

 area in the hybrid S. Catesbaei, excepting that none of these 

 cells appear as intrusions among the conducting surface cells, 

 and that they extend deep into the detentive surface. The 

 writer infers the probability that this region represents a primi- 

 tive glandular surface. 



On the normal detentive surface the hairs are short, .3-4 

 mm. in length, but numerous, 7-8 per field. The hybrid pos- 

 sesses a normal detentive surface with polygonal cells and no 

 glands. Stomata are present. The hairs are intermediate in 

 size and number. They are .6-7 mm. long, with 5-6 per field. 



Transverse Sections of Tube 



S. Drummondii, as has been previously noted, shows in trans- 

 verse sections of the tube-base epidermal cells swollen into 

 papillae ; below these, two subepidermal layers, a loose mesophyl, 

 and 1-2 subdetentive layers occur. 



In S. Sledgei the epidermal cells are oval. Below them are 

 three layers of subepidermal cells. The mesophyl is loose with 

 many air spaces. The mesophyl cells contain the same peculiar 

 contents noted in the section of 5. Drummondii. In this form 

 however the cells so supplied are arranged in a continuous 

 layer in the mesophyl tissue, below the false palisade tissue. 

 There are 1-2 layers of sub-detentive cells. 



In S. areolata there are two layers of subepidermal cells; 

 and two layers of sub-detentive cells. The mesophyll is loose 

 as in both parents. There is a suggestion of the peculiar bands 

 of special storage cells, as in the case of S. Sledgei, though the 

 layers are not continuous. 



Flowers 

 5. flava, S. purpurea, S. Catesbaei 



The flower of 5. flava is pendulous and measures 7 cm. in 

 length, 13 cm. across. Those of S. purpurea are smaller, 4-5 

 cm. long and 9 cm. wide. In specimens at hand of 5. Catesbaei 

 the flowers are intermediate in size, 5-6 cm. long and 10-12 

 cm. wide. Other specimens seem to point to a greater robust- 

 ness in it than in either parent. 



The bracts in all three are small, covered with honey glands 

 and a few stomata. The glands are distributed over the central
