or more or IcvSs spreading, truncate and compressed at the mouth, otherwise 

 inflated, especially along the keel; stylus minute, subulate; cells of lobe aver- 

 aging about 14 M along the margin, 16 fx in the middle, and 23 at the base, tri- 

 gones distinct, triangular with straight or bulging sides, intermediate thicken- 

 ings very scanty, oval; cells of lobules with numerous intermediate thickenings 

 and irregular cavities: underleaves distant to subimbricated, plane, broadly 

 ovate, 0.3 mm, long and 0.27 mm. wide when well developed (but often much 

 smaller), cuneate at the base, bifid one third to one half with a narrow sinus and 

 broad divisions, rounded to acute at the apex, entire or unidentate on one or both 

 sides: inflorescence autoicous: 9 inflorescence borne on a more or less elongated 

 axis, usually giving off a branch just below the involucre; bracts in about three 

 pairs, those of the innermost pair complicate, deeply and unequally bifid, the 

 lobe oblong to obovate, about 0.9 X 0.6 mm., rounded to very bluntly pointed 

 at the apex, entire, lobule ovate, about 0.7 X 0.45 mm., rounded to obtuse at 

 the apex, bearing close to the base a slender lanceolate stylus, measuring about 

 0.2 X 0.06 mm. when well developed; innermost bracteole connate on one side 

 with a bract, oblong-ovate, about 0.7 X 0.4 mm., bifid about two thirds with a 

 narrow sinus and suberect rounded to acute lobes; perianth about half exserted,. 

 about I mm. long and 0.75 mm. wide, oblong in outline more or less compressed 

 with sharp lateral keels, rounded to truncate at the apex with a short beak, 

 entire or very minutely crenulate at the mouth, ventral keel broad and sharply 

 two-angled, dorsal keel sharp, about half as long as the perianth, sometimes ac- 

 companied by one or two supplementary keels, margins of keels smooth: <? 

 inflorescence occupying one or two globoid spikes borne below the involucre 

 (and the subfloral branch); bracts in two or three pairs, closely imbricated, sub- 

 equally bifid with blunt lobes and an arcuate keel; bracteoles minute and bifid: 

 capsule about 0.4 mm. in diameter; spores averaging 30 ^ in short diameter,, 

 greenish brown, thick-walled, the surface bearing scattered circular spots, each 

 composed of a series of minute radiating ridges; elaters about 220 X 15 At> trun- 

 cate, with a single reddish spiral. (Figures 1-9.) 



On trees. Sanford, Florida (S. Rapp, Nos. 18 and 21). No. 18, collected 

 in June, 191 1, may be designated the type. The accompanying species are 

 Leptocolea Jooria?ia (Aust.) Evans and Microlejeunea hullata (Tayl.) Evans. 



The new species belongs to Spruce's subgenus Trachycolea, which Stephani^ 

 has recently renamed Galeiloha on account of the fact that many of the species 

 have perfectly smooth perianths. According to published descriptions the 

 female inflorescence in certain members of this subgenus is borne on a short 

 lateral branch, while in others it is borne on the main stem or on a leading branch. 

 In Stephani's opinion, however, the inflorescence is invariably borne on a short 

 branch, and any other interpretation is based on a misconception. According to- 

 his account the inflorescence sometimes seems to be terminal on a leading branch, 

 but when this is the case an apparent innovation is always developed below the 

 involucre and this apparent innovation really represents the continuation of the 

 main axis. In the course of development the portion of the shoot bearing the
