The Gleichenias are not utilized in Hawaii in any way. The 

 uluhi is eaten by cattle and goats, in the absence of more desirable 

 forage. The petioles, if properly gathered and prepared, would 

 undoubtedly be excellent material for the manufacture of light 

 basketry. At present uhihi is an undeveloped resource.

BRYOLOGICAL NOTES 

 I\\ A Xew Hybrid ix Physcomitrium 



By a. LeRoy Andrews 



Begun in the fall of 1912 and resumed in the spring of 191 3, a 

 considerable reclamation project was carried out in Ithaca, X. Y., 

 as a result of which a tract of cat-tail marsh at the head of Cayuga 

 Lake was converted into something more nearh' approaching 

 terra fir ma. The new soil was a very fine silt pumped from the 

 Inlet by suction-dredge. Among the br^-ophytes which imme- 

 diately established themselves upon it, Physcomitriiim species were 

 especially well represented. Material collected in the autumn of 

 1913 shows abundance of Physcomitrella patens (Hedw.) Br. & 

 Sch. together with some Aphanorhegma serratum Sull. and 

 Physcomitriiim immersum Sull. Occasionally also a strange 

 emergent capsule was noted, not identifiable with any moss- 

 species, but obviously a hybrid. These capsules were not well 

 matured and were so sporadic in occurrence that it was difficult 

 to collect satisfactory material for their study, but finally at a 

 point where the more clayey soil of the hillside projected out into 

 the new silt covering they were found in greater number. At 

 this point were found the following spring (1914) capsules of 

 Physcomitrium turhinatum (Michx.) Brid. together with those of 

 Physcomitrium Hookeri Hampe.* The 9 parent of the hybrid 

 was clearly Physcomitrella patens, the cT parent was evidently 

 Physcomitrium turhinatum. The description follows, the sporo- 

 phyte alone partaking of the hybrid nature, the gametophyte 



* The station for P. Hookeri is, so far as I know, the first east of Ohio.
