Morphology of the Pitcher of the Cephalotus follicularis. 181 



pitcher virtually consists of a calceolate expansion of the far side of 

 the funnel from the main axis. 



Fig. 7. Nectariferous petal of Aconitum (after Asa Gray), showing 

 petiolar portion (claw) and calceolately pouched lamina. 



Plate VI. — Fig. 1. Interrupted leaf of Croton piduratus. Distal 

 portion of lamina peltate, forming an oblique funnel. Proximal 

 expansion simply narrowed into the attenuated portion. 



Fig. 2. Another of the same. Here, however, the upper part of 

 the proximal expansion is peltate, so that the filamentary mill rib 

 appears as " excurrent " from the lower leaf -surface. 



In Plate V. the figures are all more or less magnified. 

 In Plate VI. they are of natural size. 



On Leioidophloios, a genus of Oarhoniferous Plants. By 

 John M. Macfaklane, B.Sc. (Plates VII. aud VIII.) 



The genus Lepidophloios was formed by Sternberg * for 

 tlie reception of certain Carboniferous plant remains, which, 

 while conforming in many respects to Lepidodendron and 

 allied genera, were distinguishable from these by well- 

 marked peculiarities. These specimens he described as 

 Lepidophloios laricinurii. To the elucidation of the life- 

 history of this species I propose devoting the present paper. 

 The following is a short resume of the literature on the 

 subject. Corda f described and figured parts of the stem 

 of a species of Lepidopliloios as Lomatophloios crassicaidis. 

 He wrought out the minute structure of it in great detail. 

 Though able to ascertain its internal anatomy, he erred as 

 to its true afiinities, since he regarded it as being allied to 

 Sempervirens and Cactus. 



When Goldenberg published his " Flora Saraepontse 

 Fossilis," he — as far as I can learn — enumerated three 

 species of Lomatophloios and two of Lepidophloios, the 

 difi'erences between these two genera, in the opinion of 

 this observer, consisting in the greater size of the foliar 

 cushions and leaf scars in the former. In a paper " On
