Botrychium strictum sp. nov. 
A tall plant with the habit of B. Virginianum with a sessile 
sterile lamina and slender spicate panicle. Roots fleshy: stems 
25 cm. or more long, slender, with slightly fibrillose covering: 
sterile leaf broadly triangular, sessile, of three equal or subequal 
2-3 pinnatifid divisions ; primary pinnae 6-10 cm. long, strongly 
decurrent on the rachis, with 8-10 pinnules on each side which 
vary from oblong-lanceolate to lanceolate ; pinnules varying from 
deeply 4—5-crenate to 5-cleft on each side, blunt or rounded at the 
end: panicle 6-13 cm. long, on a slender stalk 5-6 cm. long, 
with 16—20 short compact branches 5~15 mm. long, placed at an 
acute angle with the axis, thus causing the entire panicle to appear 
spike-like: sporangia much crowded, large, nearly 1 mm. in diam- 
eter: spores pale yellow. 4 
Japan: Sapporo in groves, Aug. 1894, A. W. Stanford (type a 
in the herbarium of the New York Botanical Garden); ‘‘in 4 
sylvis Takaosan., prov. Musashi, 10 Oct. 1885” comm. J. Matsa- : 
mura, U. I have also seen a specimen in the Museum of the /ar- : 
din des Plantes at Paris, and one in the herbarium of Mr. B. D. 
Gilbert. The species has hitherto been reported from Japan under 
the name of 4. Virginianum but it is clearly a very distinct species, 
differing widely in the cutting of the leaf and in the narrow spike- — 
like panicle which is also much shorter than in our familiar species. 4 
In the new species the mature panicle scarcely overtops the sterile 4 
leaf when laid on the herbarium sheet. :

Botrychium tenuifolium sp. nov. 
A slender-stemmed species allied to B. obliquum but with the . 
segments thin and reduced to nine innumber. Stem very slender, 
2-4 cm. long, I-1.5 mm. thick: leaf 3.5-5 cm. long, 3-6 cm. 
wide, usually consisting of only nine segments (2. e., strictly biter- 
nate), with the three divisions subequal ; occasionally larger forms 
show a pair of additional lobes on the terminal division ; segments
