T. peltatum — pel-ta'-tum (peltate), 

 Baker. 

 A very curious species, of small 

 dimensions, discovered in Samoa (where 

 it clothes the branches of trees) by 

 the Rev. T. Powell, who states that 

 it is quite peculiar in habit. " The 

 different branches of the caudex," 

 writes the discoverer, " run upwards, 

 but so closely together that the margins 

 of the fronds overlap each other. The 



fronds all lie flat upon the tree, so that the whole Fern has much the 

 appearance of a delicate foliaceous lichen or frondose Jungermannia." — Hooker, 

 Synopsis Filicum, p. 73. 



T. Petersii — Pe-ters'-i-i (Peters'), Asa Gray. 



According to Eaton, this tiny plant is found growing in broad patches 

 in the shade on sand rocks kept constantly moist by the running water 

 near the Sipsey River, in Winston County, Alabama, where it was first 

 discovered by the Hon. Thomas Min»tt Peters in January, 1853, and in 

 other neighbouring places, but always near running water. Its fronds, 

 produced from a thread-like rhizome, are seldom more than ^in. long and 

 vary in shape from linear to spoon-shaped ; they are sometimes entire and 

 sometimes notched or slightly lobed. — Hooker, Icones Plantarum, t. 986.
