56 BOTANICAL GAZETTE. 



Dentaria laciniata. — In Vol. I. of the Gazette I notice some remarks on varia 

 tions in Dcntuvia htciiiiata, Miihl. A year ago while botanizing in Williamstown, 

 Mass., I came across a few i)hmts which had very nuuh the aspect of D. di-pJit/Un, L., 

 having the two alternate leaves witli ovale leaflets, lint the lateral leaflets of the stem 

 leaves were 3-parted and the terminal 8-lobed; the lateral leaflets of the root Iccives 2-di- 

 vided and the terminal 8-parted. The divisions were cut-toothed or even lobed. The 

 root stock seemed to be intermediate between that of I>. (I/pIit/lJi/ and of J), lacinidta. I 

 consulted with the late Prof. Tenney and he thought it might be D. laciniata, but as this 

 hart never been found before in Williamstown, and £). diphylla was very common near- 

 it, I put it in my herbarium with the name D. dipJii/lla, L. This spring I sent a speci- 

 men to Dr. Gray, who replied, "One of the least laciniate forms of I), laciniata.'''' The 

 "Manual" says: "All these species except the first (Z>. ma.cima, Nutt., B., 7ieterophylla 

 Nutt., D. lacininta, Muhl., and B. multifida, Muhl.,) probably run together." The query 

 arises in my mind, Why except the first? The "Manual'' also says of Z>. diph>/lla^ 

 "petals white." I have found them often with a decidedly pink coloring. Perhaps 

 this will be a partial answer to Mr. Meehan's question in the Gazette of February^ 

 1877. I hope Botanists will stud}" up the variations in this genus and report results. —

Recent Puklications. — American Jnunial »f Science and Arts, April. — There is 

 a short review of the "Flora of Tropical Africa; by Daniel Oliver. Vol.111. Umhel- 

 lifcrip to Ehi'nacca!.'' The order of Comi)ositte is represented by 117 genera, 17 being 

 peculiar to this Flora. The only large genus is Vcrna/iia, with 78 species. 



The Anwrican Naturalist, May. — W. J. Beal has an interesting illustrated paper on 

 the "Hairs and Glandular Hairs of Plants, their Forms and Uses." 



Bulletin of the Turrei/ Botanical ClaJi, Marcli. — Prof. O. R. Willis has an article on 

 the "Growth of Exogens," and Mr. N. L. Brilton gives quite an extensive table on the 

 subject of the fall of leaves. 



Li»t of Native and Exotic Verna in the Green-Houses and G nnuids if J. Warren 

 Merrill, Candjridge, Mokh. — This is quite a formidable list and surely shows great labor- 

 on the part of the proprietor and no sparing of expense. Mr. 3Ierrill wishes to ex- 

 change dried fronds with those who have new varieties in duplicate. 



A Cutaloi/ue if the Fliacerimj Plants and Higher Crypt ogams grmring without cnlti* 

 Vidian icithin thirty miles of Yale College. Published by the Berzelius Society. — This 

 is an elegantly published list prepared bj' the students of the Shefiield Scientific 

 School. There is an introduction by Prof. D. C. Eaton, and also a good map of the 

 territory embraced. The Phaeuogams foot up 1,283 species, the Cryptogams (includ- 

 ing ^4c?v>£^eMS, Miisci and Hepaticce) '2"'^, u\&k.mg 1,506 species enumerated in the cata- 

 logue.

Ferns of North America by Prof. Daniel C. Eaton, Parts IV and V.— This publi 

 cation is making its appearance much more promptly than was exi)ccted and the double 

 number before us shows as fine Avorkmanship as any of the preceeding numbers. If 

 anything, the |)lates are finer than before and the ferns lie as tresh before you as if just 

 pressed. This number contains plates and descriptions of Aspidiwm Nevadense, Eaton 

 (n. sp.), Pelliva densii. Hook., and P. pulchella. Fee., Gheilanthes ciscida. Davenport, and 

 C. Clecelandii, Eaton, Aspleniiiin uiritiim, R. Br., Aneinria Me.vicana, Klotzch, and A. 

 adianttf olia, Swartz, Asplenium Buta-mnraria, L., and A. Sept 'ntrionale . Hoftm. Our 

 only objection is that the plate of Asplenium unitiim is so huge that it does not allow 

 any room for trimming when we come to bind.
