478 Eaton : Pteridophytes observed in Florida 



less winged beyond the middle by the decurrent bases of the 

 secondary pinnae ; secondary pinnae triangular-lanceolate, acu- 

 minate, contiguous, the rachises narrowly winged ; ultimate pinnae 

 linear-oblong, obtuse or rounded at apex, nearly smooth above, 

 more or less setigerous beneath, cut half-way to the costa by about 

 seven pairs of rounded, toothed segments ; veins of lower segments 

 forking once or twice, those of the upper ones simple, thickened 

 and prominent on the upper surface at the apex; sori 1-3 on 

 the lowermost segments, one on the upper, approximate near the 

 main rachis of the pinna; indusia fugacious. 



A very fine large species, widely distributed in India and Mal- 

 aysia, now apparently well established in a piece of swampy woods 

 at Oviedo, having escaped from the greenhouse of Mr. T. L. Mead. 

 The fronds are often more than 15 dm. in height, the stipes suc- 

 culent and whitish as if covered with a bloom. The basal scales 

 are sometimes 1 cm. long by about 1 mm. wide, bristly-ciliate on 

 the margins and not infrequently setigerous on the surfaces. In 

 falling they leave brown, inverted V-shaped scars. Mr. Mead 

 procured the original plants from Reasoner Bros, of Oneco, as 

 Cibotium Baromctz. It is a very prolific species, and spores of 

 some plants I procured from the same source germinated freely in 

 other flower-pots in a living-room, and came to maturity. It 

 would thus appear amply able to take care of itself in the rich 

 .swamps of middle Florida. 



.Dryopteris stipularis (Willd.) Maxon 



* 



^Rootstock erect, 7.5 cm. high, about 3 cm. thick ; stipes 3- 

 5.5 dm. long, 3-4 mm. thick, terete, light-green, scaly and finely 

 pulverulent at base, smooth above ; scales veiy dense at base, 

 the lower 1 cm. long, 5 mm. wide, the upper smaller, falcate, 

 acuminate, very thin and hyaline, soon withering and deciduous ; 

 rachis, nerves and indusia more or less strigose-pubescent ; fronds 

 4-6.5 dm. long, 2-3.5 dm. wide, gracefully arched, broadly 

 lanceolate, pinnate ; pinnae approximate, opposite or nearly so, 

 linear-acuminate, the lower pair approaching and deflexed ; the 

 upper basal segments of the lower 3—4 pairs enlarged, 1—2.5 

 cm. long, 0.5-1 cm. broad, with 5-10 pairs of segments, often 

 fruited, having the aspect of miniature pinnae, deflexed under the 

 frond at right angles to point of insertion. Aspect very similar to 

 that of some forms of D. patens but readily distinguishable through 

 the stout erect rootstock, the large chaffy scales and stipular ap- 

 pendages of the lower pinnae.
