. The ferns of North America [microform] : colored figures and descriptions, with synonymy and geographical distribution, of the ferns (including the ophioglassaceae) of the United States of America and the British North American possessions. Ferns; Fougères. il1 :i!i i'l I "fill i if 111 'i i 1 iiii!!'"' 14 FERNS OF NORTH AMERICA. quite to the midrib, entirely concealing the sporangia, which are borne on the upper part of the very obscure forking vcinlets. Plants cultivated in the moister atmosphere of eastern conservatories have the pinnules less revolute, and sometimes quite flat and destitute of sporangia. The pinnules have then much of the roundish-quadrate form seen in Pellcea Wrightiana, but are considerably smaller, even when, as is often the case, the fronds are only twice pinnate. Plants of this kind pass for P. bella among florists, but have probably little to do with Platyloma bellwn of Moore. I am under obligations to Hon. J. Warren Merrill for a full set of cul- tivated forms of this species. Plate XLVIL, Fig. 7-10. — Pcllaa Oniithopiis, drawn from a plant sent by Mrs. Cooper from Santa Barbara.
