unfortunntc contrihiitors? Notico Crenstii twire 

 in Mr. rrice's communication, for crcnata, and 

 one of tliese in hir^^^o IcKcrsivs a heading at that." 

 [Having boon told that the siihjcct had been 

 " worked up at Camhrid.u;c," no pains wore talvcn 

 to hiok up the mutter beyond notieinj; tlie rehi- 

 tion of the genus to Abohi-ea. "Crensta" wa.s 

 our correspondent's orthography, and not the 

 ty[)Ographer'8, and what witii the capital and j)e- 

 culiar spelling, we took it for an aboriginal pro- 

 per name. We did not know ui' had our old 

 friend Tlanera Rii-hardi, to deal with. The Ger- 

 niantown Nurseries in time i)ast have distributed 

 this tree i)retty freely, and so we supjtose have 

 those of Flushing anil elsewhere, and we suspei't 

 that though the Woodland's tree may be the 

 finest, it is not by a long way the oidy specimen 

 in the country. All this trouble comes from so 

 many synonyms. — Ed. CJ. M.] 



Chemic.vl Hygroscope.— F. INI., Ontario, Can- 

 ada, asks : — " What shade of color or number 

 should the Hygroscoi)e represent in a green- 

 house or conservatory to keep the plants in 

 best health, say when thermometer runs from 

 60° to 05°. " 



[The Hygroscope is such a recent invention 

 in its cheaper forms, that we can say little of its 

 application to plant culture, especially :is expe- 

 rienced gardeners do not find much dilliculty in 

 regard to the atmospheric moisture. In the use 

 of the Hygroscope, however, all we can say is 

 that the bluer the tint the drier the air, while 

 the deeper the pink the more moisture. — Ed.

Nam>: OK Pi,ANT.— N. says:— "In June Inst 

 y(>ar, near Mauch Clmnk, Pa., by tlie rail side, 

 and peeping out of the woods, I came upon a 

 very pretty shrub. It wjus not (lowers that 

 pleased, for it was out of bloom ; but iUs berries, 

 of every shade, from deep red to crimson, seemed 

 to speak for it a place in the shrubbery. lam 

 puzzled to identify tlic plant in nursery cata- 

 logues or books. It was a favorite with all the 

 pleasure parties which I met. All bore it com- 

 l)anion to the other woodland flowers of the sea- 

 son. If I have recalled the plant by the above 

 traits, you will oblige ni;iny n-aders by giving us 

 its name." 



[Not much to identify a plant by; but proba- 

 bly the Canadian Holly, Nemopanthes canaden- 

 sis, and well worthy ol cultivation. — Pxl. G. M.] 



Insect on the Grape. — Some time since, a 

 Wilmington, Del., correspondent wrote about a 

 peculiar trouble with his grape vines, and which 

 we suspected was caused by an insect unknown 

 to us, and advised the sending to Prof. Riley, 

 which it api)ears he has done, and Prof. 11. kindly 

 sends us the following response : — 



" From specimens just sent me, the insect in 

 grapery (G. M., Nov.) at Wilmington, Del, is the 

 grape leaf-folder (Desmia maculalis). See my 

 Third Rep., p. Ol. Since that was written, I have 

 found it worst on Catawba, Goethe, lona, Isa- 

 bella, Croton,Diana and Creveling — least on Con- 

 cord, Cynthiana, Louisiana and Martha. Bring 

 hands quick together and crush worm in fold. 

 Destroy chrysalides in Fall."

HORTENSIA OR HORTENSIS. 



HV T. 



In the Monthly for January last, I endeavored 

 to show that the correct name for the common 

 Hydrangea is H. llortensia, and ni support of 

 my view, cited authorities and gave reasons that 

 would convince most persons of its accuracy. 

 The Rural New Yorker, however, still maintains 

 that the plant should be called H. hortensis, and 



on February 17th reproduces my note — which is 

 very fair — that it may repl}' to it in a manner 

 which can hardly be characterized as fair. I 

 cannot ask you to reprint the Rural's remarks, 

 as it occupies over one and a half of its ample 

 columns in its attempt to show that others, be- 

 sides itself, have used an incorrect name ; in- 

 deed, that journal finds such evident satisfaction 

 in re-asserting its own way to be the right one, 

 that I would not disturb it, did it not singularly 

 misrepresent one of the authorities I cited, and
