MOSSES. 87 
leaves are in both cases linear; the seeds are 
in both cases produced from cones or spikes ; 
the formation of the archegonia and embryonic 
pods of the one is similar to that of the corpuscles 
and embryo in the other, but in these points the 
likeness begins and ends. The resemblance 
which we see between the Lycopod and the 
conifer, is like that which exists between the 
cucumber and the passion-flower, the water-lily 
and the poppy and magnolia. In the Composite, 
the largest of all Phanerogamous orders, the habit 
of almost every other order of the vegetable 
kingdom crops up again. Every platform of 
plants is found in close analogy with every other 
platform. There is nothing in Exogens which we 
‘do not find in Endogens; nothing in flowering 
plants which we do not find among flowerless 
plants. In the strange Brazilian family of Podo- 
stemas we see liver-worts and scale-mosses in 
flower ; while in those curious trees of Australia, 
the Casuarinas, reappear the leafless branches and 
singular joints of the Equisetums or Horse Tails 
of our marshes. But we must remember that 
often where there is the greatest amount of appa- 
rent affinity, there is the least real affinity; that 
in judging the value of such mimicries, echoes, or 
resemblances “like is an ill mark.” There is no 
true homology, but a mere analogy which is often
