Sarracenias with that of Their Parents 25 



papillae. The stomata and glands are grouped in special tracts 

 as in 5. Drummondii, but they are wider and less well defined. 

 There are strong hairs scattered abundantly over the lid sur- 

 face, especially around the margins of the window areas. They 

 are much stronger than in either parent. 



Inner Lid Surface 



The epidermal cells of the inner lid surface of 5. Sledgei (PI. IV, 

 fig. 20) are longer than broad, and wavy-walled. In 5. Drum- 

 mondii (PI. IV, fig. 18) they are about as long as broad, with 

 walls slightly wavy. S. areolata (PI. IV, fig. 21) has cells re- 

 markably intermediate in size and shape. 



Stomata are sparsely distributed over the inner lid region 

 of 5. Drummondii, where the average per field is .59. In 5. 

 Sledgei they are quite abundant — 3-4 per field. In the hybrid 

 they are quite intermediate in number — 2-3 per field. 



The hairs of the lid in S. Drummondii are variable in length. 

 They exceed in their greatest length the hairs of S. purpurea, 

 reaching almost 2 mm. in length, while the shorter ones are 

 only .3 mm. long. 



Itf 5. Sledgei on the other hand the hairs are of a uniform 

 length. They are stout and short, varying slightly from .55 

 to .88 mm. long. None are as short as the shorter of those of 

 S. Drummondii, .3 mm. In S. areolata the hairs vary greatly 

 in length after the fashion of the 5. Drummondii parent. There 

 are hairs present as short as the shortest of S. Drummondii, 

 but the longest hairs are a little over half as long as the longest 

 hairs of 5. Drummondii — 1 mm. Hairs .7-9 mm. in length 

 are the most numerous. That is the influence of the S. Drum- 

 mondii parent is shown in the tendency to wide variation in 

 length, and in the lengthening of all of the hairs. The glands 

 in the three forms are fairly numerous — 4 in S. Drummondii, 

 4 in S. Sledgei, and 4 in S. areolata. 



Conducting Surface 

 Conducting surface cells here do not show the exact relation 

 shown in the other hybrid. In S. Drummondii (PI. V, fig. 25) 

 the cells were large and measured .15 mm. in length. In S. 

 Sledgei (PI. V, fig. 27) the cells are about .09 mm. long, and are 

 narrow and oval in shape. In S. areolata (PI. V, fig. 28) the 

 cells are of the same length as in 5. Sledgei, but are wider and 

 in shape are halfway between the parent forms.
