BOTANICAL GAZETTE. 47 



Five lilliDiriapliic plates arc added, uivin^- iiliislralioiis of niiiely-sevcn species of 

 these fun. t,n. Tliere an; also two lists of sjjucies: one in wliieli they are arranged un- 

 der their respective orilers or families, the other in wliicli lliey are grouped according 

 to liieir nourisiiing plants. From the hitter list it appears that much the largest num- 

 ber (jf species has been found on the European grape-vine, Vitis laiidfera, L., whose 

 l>arasites nmnlierone hundred and lifty species. VUIh fj<i1)r\iHC(i, L., stands next, nour- 

 ishing tifly-four species. Many of tJie^e fungi are American. 



We consider this work a most valuable addition to myeological literature and an 

 important aid to the student of fungi. It is also a work that commends itself to those 

 interested in grape culture. — Ch.\s. II. Pkck. 



N.\TUK.\i. Eadicai- Gi{.\KTi.\(t. — Mucli more wonderful than the ''Natxirnl Graft- 

 iiirf' recorded l)y the respective editors of liie Gazette and Bulletin, in the September 

 and December numbers, 1877, is the case of Gamo-radicai (Tiafting accidentally pro- 

 duced here in Ames, by Mrs. Dea. Kingsbury, potting two i)hints of the "Deer's 

 Tongue ' and -'Rat's tail" Cactus, resulting in a jirnfuse croj) ol the latter Lssuing from 

 the extremity of the leaves of the former! There is no mistake about this, the writer 

 having examined the i)lants, and secured a sjtecimen, and any one can tiy tlie experi- 

 ment for himself. It did not remilt fnnii the, effert nf pollot, us luither plunt iixm in 

 bloom, nor indeed has ever bloomed I — \\. Bl'HOEss, Ames, loini. 



Uecent Pubijcations. — Ameririin ,/onr/inl of !<cienee <tn,d Artu, Marcli. — Dr. Gray 

 gives a Supplementary Note to the Review of Darwin's "Forms of Flowers," Ijeing an 

 answer to some statements made by ^Ir. Median in the Torrey Bulletin in resiject to 

 cj-oss terlili/.ation. The Botanical Necrology for 1.S77 is also giv. ii ami contains an un- 

 usual number of noted names. Ten names are reported. 



T/ic Anieriran Xaturulist, April. — Rev. E. L. Greene continues his "Rambles of a 

 Botanist in New 3Iexico," contining iiimself in this second paper principally to the 

 sylva. Mr. C. G. Pringle has an interesting note on "Cleistogamous Flowers in Dan- 

 Ihonia." 



Bnlletin of the Torrey Botuniciil (Jlnb, February.— ]Mr. I. II. Hall gives a very inter- 

 esting account of Opantia FirtisJ ndini, UC, of Southern Italy and otiier Mediterranean 

 countries. Its main use in the Orient is to furnish a hedge, and next to furnish food. 

 Dr. Gray advi.ses some younger botanists to make haste more slowly, making this the 

 basis of some remarks u])<Mi Mr. Wolle's pai)ers on Fresh Water Algtc. Jos. Schicnk 

 writes of "The Excentiicity of the pith in Rhus Toricodeitdron." His observation 

 goes to prove thai this excenlricity is ciau.sed by the absorption of water 1^^ the lateral 

 rootlets. This more abundant supply of water produces greater activity in the cam- 

 bium cells, their turgescence would be more intense anil the ducts larger than (m the 

 opposite side. 



Field iiofl Forest, Jan. and Feb.— The Botanical part of this double numlx'r is un- 

 usually full. Mr. Thomas .Morong writes of the Flora of Maltha's Vineyanl and Vi- 

 cinity, and also m the "Field Record" notes two forms of I'lmituijo nuijor that had been 

 pointed out by Mr. A. Commons, of Centerville, Delaware. An article by Dr. Gray 

 ui)on the same subject, in the i)reseiil iiumbei- of the Gazette will be read with interest. 



The Valley NatarnliHt, March and April.— This enterprising sheet appears ])romptly 

 with every month and bids fair to become a useful medium for scientific notes. 



On the TniH spi ration of Plunts, Ijy J. M. Anders, ^l. 1)., Ph. D.— A very interesting 

 series of observations is recorded in this paper, showing that, under favorable circum- 

 stances, the amount of watery vapor transpired by plants is something wonderful. Ac- 

 cording to the rate deduced from his experiments the Washington Elm, at Cambridge, 

 not a very large sizetl tree, would transiiire 1% tons of watery vapor in twelve hours
