guard against describing a lichen as new ; and that the same facts in 

 regard to distribution prevail aniong the fungi, mosses and other of the 

 lower plants, as among the lichens. This coincidence with r^^ference 

 to the Characcae, between America and Asia, was noticed by Dr, Allen 

 in tlie October number of the Bulletin. It mi^jht be interesting]; to 



attempt to trace it also between Western Africa and Eastern Asia.

What is a Frond 7 — Some pteridologists insist on limiting 

 the idea of a frond to what would be the lamina in an ordinary leaf, 

 but the popular idea embraces both stipe and frond. Even botanists, 

 usually critical when referring to ferns, sometimes relax the rigid rule 

 and lake in the stalk and all when speaking of palms, I sympathize 

 somewhat with the popular view. We have a double meaning for the 

 ordinary leaf, nnd why not for the 'Meaf' of the fern ? If a student be 

 asked to describe a leaf he rightly tells of the lamiuci, the petiole and 

 the stipules. If we read that a plant has the. peduncles longer than 

 the leaves, we do not understand that comparison is limited to the 

 leaf-blade alone. Indeed, the very term ''leaf-blade" involves the 

 idea that something else than " blade '* is wanting to make the idea 

 perfect. Yet, when we come to describe a leaf in its stricter sense, 

 we sav it is coriaceous, or serrate, or ovate, and we understand that we 

 then fimit the idea to the lamina alone. Why cannot we rightfully 

 have the same duplex idea in pteridology ? Indeed, the classical 

 frotis w^as certainly not limited to the green blade, nor does it seem 

 probable that it w^as so intended when introduced into botanical 

 lano-ua^^e. Thomas Mekhan. 



^ 8. Notes on the Middlesex County, N. J., Flora.— The fol- 

 lowing are new stations for a few somewhat rare plants detected in 

 Middlesex Co., N. J.: Sattcllaria i/iiegrifolia, \.., at South Amboy ; 

 Quercus Phellos, L., at South River; Euphorbia corollaia, L., and a 

 number of ])ine barrens plants at Burt's Creek ; Oroiiiiiim aquafkiiin, 

 L., zr\d Habeiiaria blcpharijr/ottis, I look, at Sayreville; Podophyllum 

 pcltaimn, L., at Perth Arnboy ; Echiiiw vidgare, L., in great abim- 

 dance, Stylosauihcs clatior, Swartz and Bromus skrihs, L., at ^e\v 

 Brunswick. The Echiiim occurs all along the track of the Pennsyl- 

 vania Railroad, from Jersey City westward. 



Prof Geo H. Cook reports the occurrence of Zj;^^rt'///w/rt'/w^w/w, 



Swartz; at Craner's Mills, just south of New Brunswick, and of 

 Xerophyllitm asphodeloides, Nutt, about three miles south of tV.e same 

 place. These localities are rather extra-limital as regards the lorrey 

 Catalogue, but are nevertheless worthy of record. This is the most 

 northern point at which the Xerophyllinn lias been found in New 

 igpsgy^ N. L. Britton.
