related species first in Osmunda and later (following Hoffman*) in 
Onoclea. Later Willdenow and Brown each published new generic 
names for part of the genus under discussion. Willdenow,} in 
1809, published the genus Lomaria, citing all of Onoclea of Swartz 
except O. sorbifolia as the basis of the name; and in the following 
year Willdenowt listed under Lomaria most of Swartz’s species 
of Onoclea. In 1810 Robert Brown$ published Stegania, before 
mentioned, for eight African members of this genus. In so doing 
he separated Spicant from its relatives, just as Swartz had done 
when he placed it under Blechnum, and its relatives under Osmunda 
and later Onoclea. 
This confusion has continued even to the present, although two 
authorities, Trevisan|| and Underwood, have shown independently 
(1) that Osmunda Spicant L. has “first claim to Struthiopteris, 
becoming Struthiopteris Spicant,’’ and (2) that the correct generic 
name for Osmunda Struthiopteris L. is not Struthiopteris but Mat- 
teuccia, established by Todaro** in 1866. 
Trevisan attempted to divide the genus Struthiopteris, recog- 
nizing Lomariq Willd. for part of it. In his key he describes 
Struthiopteris as having median sori and ascribes marginal sori to 
ria. Trevisan discusses but three of the North American 
Species, Spicant, doodioides, and polypodioides, which he places 
under Struthiopteris. A careful examination of the North Ameri- 
can material in the New York Botanical Garden herbarium does 
Not justify this division. The term “median” is not applicable, 
€ven relatively, to the indusium in any of this material; the sterile 
“sension outside the indusium may be perceptibly wider in the 
young leaves, but the conditions in the mature fronds do not 
Justify the use of the term. NordoS. Spicant and S. polypodioides 
; a from any of the other species in the relative position of the 
indusium.
