ACRosTicnC.tr. 9/9 



plant of Elliot. My specimen is 10 inches, the 

 leaf large and broad, sheathing the stem, which 

 has two other sheaths at the base, bracts small 

 squamiform round. Autikon 42. Ic. 61. 



3. AcR. ACUMINATA Raf. MlcrostifUs bra- 

 cJiypoda Gray. Stem triangular, two angles 

 winged, leaf ovate (acute?), raceme elongate 

 slender, pedicels short adpresssed ; sepals oblong 

 inner linear, lip hastate, trilobe, '2 lobes rounded 

 middle one acuminate. — Shady swamps of On- 

 eida and Herkimer in New York. Estival, 

 stem 2 to 6 inches. Deemed akin to the next 

 European sp. by Gray ; which I add to show the 

 distinction. 



AcR. ciLiFOLiA Raf. Opiirys cUifolia &. O. 

 monophylos L. Malaxis Persoon, MicrostyVs 

 Lindley. Stem triangular, leaf ovate acute 

 ciliolate, raceme slender as long as stem, pedi- 

 cels short patent, sepals ovate, inner lanceolate 

 lip entire concave acuminate. — Swamps of Prus- 

 sia and the Alps. Perhaps two sp. are even 

 blended here ; but I have no materials to dis- 

 tinguish them properly : let the European bota- 

 nists do so; but restore my genus Acroantlw.s 

 1808 adopted by Desvaux. 



ACROSTICHUM, this linnean genus is now 

 distributed into 14 Genera, since Smith and 

 Wildenow reform of the ferns! Woodsia, Schi- 

 zea and Woodwardiu belonged once to it ! the 

 A. lanceolatum is become the Nephrodium ac- 

 rostichoides of India, not ours, both of my ge- 

 nus Synotelis. His 4. platineuron is our ^5- 

 plenium ebeneum. His A.polypodioides is our 

 Polypodium incanum — A, ilveiise is Woodsia 

 — A, oreolatum is Woodicardia — A, Uneatum 

 Mg. is Schizea Pusilla ?
