the flat ideal section which he gives, he could exhibit only a single seed 
attached to each scale; his object was to show the method of "attach- 
ment, and not the number of seeds on each. Lindley adds a particular 
description of the specimen, and agrees with Henslow as to the affini- 
ties of the fossil, asserting that its relation to Zamia is shown " in 
every point of its structure. 
Endlicher, in his revision of the tycadea for the • Genera Plantarum ' 
(1836), established the genus Zamiostrobus for this cone, giving as the 
most remarkable character of the genus, that the carpellary scale bore 
on Us upper surface, a little below the middle, a single seed. Neither 
Henslow nor Lindley specified the number of seeds borne on each scale, 
and Endlicher, misled by Henslow's diagram, erroneously assumes that 
there is only one, and on this establishes a new genus, which, with good 
reason, he characterizes as a very remarkable one. He considers it in- 
termediate between Encephalartos and Zamia. 
Presl, in Sternberg's 'Flora,' parts%ii. and viii. p. 195 (1838) 
established the genus Zcmites, giving in his diagnosis of the genus the 
characters of the fruit as-strobiljform, oval, pedunculate, with large 
imbneated scales spirally arranged. He describes twenty-five species 
hve based on stems and the remaining twenty on leaves. Where he o-ot 
Ins fruit characters is not apparent, as he does not seem to have had 
any specimens of fruit. Morris, in a revision of the fossil Cucadetr 
published m the < Annals of Natural History,' 1st series, vol. vii p 115 
(1841), adopts Presl's genus, and places in it the fruits figured by 
Lindley and Hutton under the names of Zamia crassa, Z. macrocephala, 
and Z. ovata. " »■ . 
Miquel, in his 'Monographia Cycadearum' (1842), accents Endli- 
cher s genus ZammtnkH, but places it at the end of the Order on 
account of its anomalous one-seeded carpellary scale. Goppcrt also 
adopts tins genus (< Uebersicht der Schlesischen Gesellsehaft ' 1 8 1 1 
p. 128), considering, with Endlicher and Miquel, that it is the' type of 
an extinct tube of C&cad^. He adds three additional species which 
had been referred by Morris, in the first edition of his < Catalogue of 
British Fossds, to ZamUes. I think, with him, that it is well to have 
a provismnal genus for detached fossd Zamia-like fruits until their re- 
la ton to stem and foliage has been established, but 1 regret that he 
-looted h„d hcher s genus with the original description, and placed in 
it three additional cones, the internal strueture of two of which was
