mens from Chiloe are assuredly only a variety, drawn out, as it would aj)- 

 pcar, l)y a warmer climate. Tlif fructification is umiuestiouably that of a 

 Trirhnmancs ; hut the (ip^ures iu (Jaudicliaud pive a very imperfect idea of 

 the plant. The brown color of the fronds and the form and disposition of 

 the pinnjE remind one oi Jumji-rmannia spfiai/iioidcs.

 men of this in j\Ir. J. Smith's herbarium has great afTiuity with 7'. dis- 

 sectum ; but the pinnae are very obtuse, and scarcely again pinnatilid.

 margin of the lower segments on the upper side of the ulti-

f It is very difficult to draw the limit between a frond pinnated (in the 

 first instance), with the rachis slightly margined, since that margin is often 

 obsolete, and that winged rachis which uiight justify the torui pintiatifid. 

 In T. rii/idum and T.anceps, the term " jtinnatifid ' is perhaps more appro- 

 priate, and the place of them would be in a dilVercnt section. They arc 

 cited here, on account of their close aflinity with some of the following 

 species.
