with the specimen marked "Chile — ex coll. Berteroana" seem to be 

 the same. There is one speciini-u, liowever, in Herb. .Montaf^ne, which 

 is different, possibly a slender sterile CallophylUs. This is marked 

 "Coquimbo (Chili), Igt. Gaudichand." Tliis specimen agrees with 

 the fi^ires of Kuetzing (1866, pi. 69) which are evidently not taken 

 from any species of Ginannia as conceived by ]\Iontagne. The other 

 Chilean specimens in Herb. IMontagne agree wiili the figures in the 

 Voyage Bonite (pi. 145, nnder f. 3). The cortex there represented is 

 not distinct, otherwise the details are characteristic of the specimen 

 that I have taken to be the type. 



The plant from La Paz, referred to Scinaia furcellata var. undulata 

 by ]\I. A. Howe (1911, p. 502), has been found to be a true Scinaia 

 and wnll be found above under Scinaia Johiistoniae. 



Gloiophloca undulata is a monoecious species with a thin cortex and 

 is to be compared wnth Gloiophloca Okamurai of Japan, to which it 

 comes very close. It appears to be a slightly broader, somewhat lower 

 species than Gl. Olamurai, with a cortex intermediate in thickness 

 between it and Gl. Scinaioides. These differences, together with the 

 widely separated geographical distribution of the two species, make it 

 seem best to keep them separate, for the present at least. From Gloio- 

 phloca Scinaioides it differs in its broader, lower, less branched frond 

 and in its much thinner cortex, while from Gl. Halliae it is to be 

 distinguished by its lower stature, greater number of dichotomies, 

 and somewhat thicker cortex. From the other two species, viz., 

 Gloiophloca capensis and Gl. confusa, it differs fundamentally in being 

 monoecious. 



Thus far Gloiopldoca undulata is known only from the type 

 material from the coasts of Chili and Peru.
