The Relation of Fungi to Other Plants

learn with the microscope that the pond scums which he had 

 thought disgusting frog-spittle are in truth tangles of exquisite 

 plants, made up of chains of slender, transpar- 

 ent cells finer than silken threads, each eel) 

 containing many tiny green par- 

 ticles of leaf green, or chloro- 

 phyll — the cause of the green 

 colour of all green plants. 



At first the most conspicu- 

 ous plants attract the attention, 

 and afterwards, in succession, 

 those less and less conspicuous. 

 They, in reality, present them- 

 selves in great natural groups, readily distinguished 

 by well-marked characteristics. 



It will be seen, as these 

 pass in review, that they are 

 conspicuous according as 

 they are complex. The gorgeous flow- 

 ering plants have complicated methods 

 of reproduction 

 — corollas and 

 honey, attrac- 

 tive to insects ; 

 ingenious sta- 

 mens, pistils, seed-boxes, and seeds. 

 The humble grasses, with their close 

 relatives, dispense with 

 gay colours and the as- 

 sistance of insects, and 

 trust to the breezes to carry 

 their pollen to its goal. 

 The pines and their allies 

 are a step nearer simplic- 

 ity, and do not enclose 

 their seeds in a seed-box 

 at all, but provide them 

 with wings for dissemi- 

 nation, and leave them exposed to the 

 wind.
