 R. ct S. 



1676 is 1523, 7th ed. 



1676 c is a var. found by Mr. Melvill in Perthshire. 

 1679 is 1526, 7th ed., but alter name to T. 

 frafcjise, Pers. 



1 68 1 c is a long-leaved var. 



1684 is 1531, 7th ed. 



1685 is 14S3, 7th ed., alter authority to Koel. 

 16S6 is 1534, 7th ed. 



1687 b is a var. found in the Isle of Wight, as also 

 var. c. 



16S8, alter authority to Ard. 



i6SS<5 is an Irish var. of the plant, with a different 

 facies to the Scotch plant. 



196 1 c is what has mostly been reported as A". 

 -albescens, DC. I have seen true arenaria from the 

 Channel Isles and the Kentish coast. 



1692^ almost explains itself, as a depauperate'var. 



1693 b is a small maritime form of the plant. 



1707 b, alter to casta, Gaud. 



1 707 b, c, d, are described in the 3rd ed. of " English 

 Botany." 



170S/S, c, two vars. described by Parnell in his 

 "British Grasses." 



Jjiob, c, d, three vars. described in the 3rd ed. of 

 "English Botany." 



17" l>, " English Botany." c, Parnell's book. 



I7i3<r, described by Mr. Townsend in his "Flora 

 of Hampshire." 



1 7 15 6, Parnell's book, c, Mr. Townsend's " Flora 

 of Hampshire." 



1 7 18 is 1546, 7th ed. 



1 7 19 is 1547, 7th ed. 



1720 is 1548, 7th ed. 

 1725*5 is 1569*5, 7th ed. 



1727 is very rare. I have seen only one gathering 

 named by Professor Hackel. But the whole of our 

 Festucre require gathering in good examples and with 

 roots. 



1728 may be held the same as 1570 a, 7th ed. 

 1730. The vars. should stand thus : 



a. genuina. 



b. pseudo-lotiacea, Hack. 



c. loliacea (Curt.). 



*733. alter name to ramosus, " Huds." 



1 734 b, a hairy var. I have it from Kent and Norfolk. 



1 741 c, described in Parnell's " Grasses." 



1 742 d, scarcely differing from var. b. 

 1 746, vars. of a very varying species. 



1749 is 1587, 7th ed. 



1750 is 1588, 7th ed. 



1750 b and c, described in 3rd ed. " English Botany." 



1751 b and c, described in 3rd ed. " English Botany." 



1752 is the plant usually named Triticum aculum, 

 DC, but which name has been denied to it by two 

 excellent critical botanists of Europe. At present it 

 is doubtful how to name our plant, and also doubtful 

 whether we have the true plant of De Candolle. 



1 757> alter to secalinuiu, Schreb. 



In the ferns the species and vars. are taken from 

 the 3rd ed. of " English Botany," they not having 

 been published when the 7th ed. was compiled, which 

 was "adapted to Mr. Syme's ' English Botany.' " 



The sequence of the genera from Hooker. 



1S03, the name alter to calcarea, Fee. 



1 8 1 1 b, c, two added vars. 



1816, added species found by Mr. YV. H. Beeby in 

 Surrey ; on the continent, by some authors supposed 

 to be an hybrid between 1815 and 181 7. 



1 S 19 is a rare Irish equisetum. 



1S29/' is a tall var. from Lough Bray in Ireland, 

 described in "Journal of Botany." 



The Characeoe are adapted to the various careful 

 publications of the Messrs. Groves, who have done 

 much to elucidate our British species. 



It is hoped that these notes will, to some extent, 

 clear away some of the difficulties in using the 8th ed. 

 of the Catalogue. Very much yet remains to be done 

 to record the distribution of our flora, though Mr. 

 Watson's works have gradually built up a mass of 

 solid information, to which future workers can add. 

 The writer of this will be glad to receive notices of 

 plants found in any county not recorded in 2nd ed. of 

 " Topographical Botany," accompanied by specimens, 

 which will be returned if required. 



Many of the writers on botanical subjects in 

 Science-Gossip do not seem to belong to either of 

 the Botanical Exchange Clubs, or to the Botanical 

 Record Club ; hence permanent records of their finds 

 may not be made ; all can help, and it is only by the 

 aid of many that the flora of a county can be kept up 

 to date. 



I shall be glad to see any observations in SciENCE- 

 Gossip on these notes, and will do my best to further 

 explain any seeming anomalies. 



I have not touched on the exclusion or inclusion of 

 introduced [species, as this may form a pretext for 

 endless disputation. 



One of the gravest objections that have been made 

 is this: "Where are we to find these new species 

 and varieties described ? " The fact is this, the 

 Catalogue is ahead of any Flora ; hence some difficulty 

 will be experienced until one or the other of our 

 standard Floras is published in a new edition.

 THE MARIGOLD (CALENDULA.) 

 By E. A. Swan. 



THIS plant belongs to the order Composite. The 

 flower is curious and interesting. Two whorls 

 of sepals form the involucre, two or more whorls 

 of petals the ray florets, and a numerous company of 

 closely packed blossoms the disc. The involucre fits
