from its parent-stock." A similar explanation is given, though some- 

 Avhat more cautiously, of the origin of another endemic species, 

 Chiococca hermudiana, which "probably originated from seeds of 

 C. alba.'''' Tlie name Hermudiana, which is here retained for the Sisy- 

 rinchiiim must, as Mr. Farwell points out in a paper reprinted in this 

 Journal for 1918 (p. 271), be assigned to the species generally known 

 as S. angustijolium ; the Bermuda plant must be called &. iridioides 

 Curtis, whose beautiful figure (Bot. Mag. t. 04) contrasts favourably 

 with that given as frontispiece to the book under notice. The plant 

 here called Galium hermudense L. is regarded — perhaps rightly — as 

 conspecific with the United States species included by Linnseus under 

 the name. The matter is discussed in this Journal for 1909 (p. 41) 

 in a paper which seems to have escaped Dr. Britton's notice ; in this 

 the two are differentiated, and the name hermudense is restricted to 

 the Bermudan plant, which is called Relhunium hernmdense. The 

 fifth of Dickinson's endemic species is Adiantum helium, first dis- 

 tinguished in 1879 by Thomas Moore, " who," as Dr. Britton informs 

 us, " was not the same man as the celebrated poet of the same name " — 

 it is not easy to suppose that anyone would be likely to consider the 

 two identical ! The other Bermudan species represented in the Sloane 

 Herbarium by specimens from Dickinson are Melilotus indica AIL, 

 Erif/eron canadense L., E. linifolius Willd., Eupatorium macro- 

 pliyllum L., Verbena urticifolia L., SclerocJiloa rigida Link, and 

 Cenchrus trihuloides L. Petiver also received from him Juniperus 

 hermudiana in fruit; of this species there is in the Sloane Herbarium 

 labelled by Petiver: '^ This from Bermudas a D. (vol. 332, f. 81) James 

 and Dickinson ": I have not met with the former name elsewhere. 

 Another early collector was the Eev. William Clarke (fl. 1710-34), 

 Avhose plants, gathered at Carolina, Bermudas, and the Caribees, are 

 in Herb. Sloane, vol. 318. Unfortunately the localities for the speci- 

 mens are not distinguished in any way : that some are from Bermuda 

 is, however, shown by a specimen (f. 34) of the endemic Erigeron 

 Earrellianus. 



It may be noted that Dickinson gives two local names which do 

 not appear in the jFZor«: "Love-grass" for the Cenchrus — "I sup- 

 pose," says Petiver, "from their prickly seeds, which may stick to 

 j^ cloaths like our Burdock or Clivers, wh. last for y*^ reason is called 

 Philanthropos " — and "Hog weed" ior Erigero7i Earrellianus : we 

 note that Dr. Britton, conforming to the absurd fashion which would 

 supply every plant with an " English " name, dubs the latter 

 "DarreU's Fleabane," which it is safe to say no one ever has called 

 or ever will call it. 



The index — evidently excellent, although the first name we looked 

 for {lielhunium, p. 308) does not appear in it — demands a special 

 word of praise in that there is but one : a method which, often urged 

 in these pages, is emphasized by Sir Edward Cook in his recent 

 delightful volume. Literary Becreations (p. 63): writing on "The 

 Art of Indexing " he says : " I lay down as the first rule, One book. 

 One index. . . . Multiplication of indexes is an unmitigated nuisance: 

 it makes reference less easy. One index alphabetically arranged is the 

 only right plan."
