40 RECORDS OF OBSERVATIONS ON SIR WILLIAM MACGREGOR’S 
Gleichema flagellaris ; Sprengel, systema vegetabilium IV, 25 (1827). 
Mt. Knutsford and Mt. Musgrave. 
Evidently a comparatively hardy fern. 
Specimens from Java and Mauritius, here compared, fully accord with the . 
Papuan plant. The G. pubescens and G. pedalis of the Western Hemisphere are 
closely allied to this fern. Among the upland-ferns, now received from New Guinea, 
is also G. Hermannu, but it came not likely from the highest elevations. 
Schizea dichotoma; Smith in Mémoires de |’ Academie de Turin V., 149 (1791). 
Mt. Musgrave. 
The plant, illustrated under the above name in Guillemin’s icones lithographice 
plantarum Australasie rariorum 20, is a much ramified form of §S. bifida, which 
species, unlike the genuine S. dichotoma, extends to far extra-tropic latitudes. 
Hymenophyllum Tunbridgense. Smith in Roemer’s Archiv fuer die Botanik I. 
56 (1797). 
At and near the summits of the Owen Stanley’s Ranges, also on Mt. Musgrave. 
Cyathea Maegregorit. - 
Trunk dwarf; fronds bipinnate; rachis beset with a brownish somewhat 
lanuginous early desiduous vestiture and at first also with paleaceous somewhat 
lanceolar long-acuminated membranes ; pinnz in outline elongate-lanceolar, rather 
rigid; pinnules narrow, quite blunt; rhacheoles imperfectly invested with crisp 
flattened hairlets ; segments of the pinnules very small, tumid, broadly recurved at 
the margin, the lower mostly semielliptic and distinctly separated, the upper more 
roundish or almost semiorbicular and sometimes confluent, but in some instances 
all segments roundish; sorus-fruits two to each segment or oftener only one; 
indusium at first globular and almost closed, at last in its upper portion irregularly 
ruptured ; receptacle somewhat longer than broad; sporangia from dimidiate-ovate 
to oblique-cuneate, narrowed gradually into a short stalk-like base or almost sessile, 
at the summit and along the greater part of one side annulated. 
Mount Knutsford, with Ranunculus amerophyllus and Decatoca Spenceru. 
What here has been regarded as the typic form of this species differs from all 
other congeners in the segments of the pinnules being quite turgid and their 
aperture only being formed gradually beneath; thus they are in structure some- 
what like the ultimate frond-segments of Gleichenia dicarpa, or like the fertile 
segments of Onoclea sensibilis. The sorus-fruits, whether one or two, occupy the
