300 THE JOUKNAL OF BOTANY 



Ncpeta Gleclioma Benth. ; Hay thorn, which Britten and Holland 

 give for Ilatvthorn ; and Ilayrijf for Gdliinn Aparine L. Such a 

 name is hardly likely to have been acquired by a plant in England 

 after the Norman conquest or anywhere near " the close of the 

 iiiteenth century." — G. S. Boulger. 



Latiiyrus Armitageanus and Oxalts Darvalliana. In Index 



Kewensis these plants stand respectively as 



'■^ Lai In/ run Armiiaqeanus Knowles & Westc. Fl. Cabinet, iii. 

 '(1840') [1889] 81 = nervosus." 



" Oxalis Darvalliana Knowles & Westc. iii. 1840. 5." 

 In this Journal for 1901 (p. 97) I pointed out that the former was 

 published at an earlier date and suggested that Westcott was the 

 authority for the species : it may be worth while to set the matter 

 beyond doubt, and to show that the Oxalis also rests on the same 

 authority. It appears from notes in Loudon's Gardener' s Magazine 

 (ix. 525 & 526 ; 1835) that both plants were published by Frederick 

 "Westcott — Loudon's mistake as to the meaning of " West." was 

 corrected by David Cameron {op. cit. 689) — in Aris's Birmingham 

 Gazette for May IS, 1835: they were grown in the garden of the 

 Birminglmm Botanical and Horticultural Society, of which Westcott 

 was a secretary, and commemorated " the late lamented Secretary, 

 Dr. Darwall, and the Treasurer, the late Mr. [James] Armitage, both 

 of whom were devotedly attached to the science of Botany, and with 

 whom the Society may be said to have originated." The newspaper 

 notices, of course, cannot be regarded as publication ; but Loudon 

 {I. c.) adapts and amplifies the descriptions, which may date from the 

 Magazine. The reduction of L. Armitageanus is doubtless accurate ; 

 the Oxalis, for which no equivalent is given in Ind. Kew., may, I 

 think, be referred without doubt to O. versicolor L., of which it was 

 originally considered a variety. The date " 1840" is inaccurate — the 

 numbers of the Floral Cabinet are dated : the history of the two 

 species may be stated as follows : 



Lathyrus Armitageanus Westcott ex Loud. Gard. Mag. ix. 325 

 (1835) ; ex Maund, Bot. Cab. vi. n. 525 (1836) ; Fl. Cab. iii. 

 81, t. 110 (Aug. 1839) = L. nervosus Lam. 

 Oxalis Darvalliana Westcott ex Loud. 1. c. p. 325; Fl. Cab. iii. 

 5, t. 93 (March, 1839) = 0. versicolor L.

Calamintha Acinos Clairv. In this Journal for 1915. p. 217 

 I suggested tentatively that C Acinos Clairv. and C arvensis Lamk, 

 are different species, basing my opinion upon a series of plants of 

 C. Acinos from limestone rocks in the Bristol and N. Somerset dis- 

 trict, and upon a series of C. arvensis from diffei-ent parts of the 

 Continent and from Surrey. The matter is still under investigation, 

 but 1 may already add that although the smaller annual plant of 

 arable fields and dry rubbly places has long been known in j^arts of 

 •Somerset, I had never seen that form in this county until August 12 

 this year. When cycling from my work on the ridge between Cleve- 

 <lon and Clifton I noticed a specimen on the edge of the road at the
