THE PLANTS OP SALISBURY'S " PRODROMUS " 63 



EosA SIMPLICIF0LL4 (p. 359). A misleading passage in Lindley's 

 Bosarum Monographic^ (p. 2) suggests that Salisbury's name 

 should be adopted by those who hold stricter views than Lindley 

 did on questions of priority : " Although Mr. Salisbury's name," 

 he says, " was pubHshed before Pallas's, and as Sir James Smith 

 observes, much the best ; yet, as herhcrifolia has been almost 

 universally adopted, I should scarcely be justified in giving up 

 expediency to a right of priority which, moreover, is supported 

 only by the antecedency of a few months."" A reference to 

 Pallas's establishment of berberifoUa (in Nov. Act. Acad. Petrop. 

 X. 379) shows that this dates from 1792, thus antedating si7n- 

 plicifolia by four years, Salisbury writes: " Descriptionem ad 

 exemplar ditissimi Herbarii Banksiani concinnavi " : the specimen, 

 however, collected in Persia by Michaux, is very small, and the 

 description (which is very full) was doubtless supplemented from 

 living plants, as Salisbury tells us he had had it in his garden for 

 two years. 



PoTERiuM AUSTRALE (p. 360) " Sponte nascentem juxta Port 

 Desire, legit — Christie." This name, although cited in DC. 

 Prodr. ii. 592 as a synonym of Accena sericea Jacq. is not quoted 

 in his monograph of the genus (1911) by Dr. Bitter, who employs 

 the name for a subspecies of A. ovalifoUa R. & P. The species 

 will stand as 



Ac^NA AusTRALis (Salisb.) comb. nov. 



Poterium australe Sahsb. Prodr. 360 (1796). 



Acsena sericea Jacq. Eclog. i. 81 (1811-16) et auct. 



Knowltonia rigida (p. 372). Although Sahsbury's specific name 

 has been generally maintained for the genus which he here 

 established, it is clear that the plant must take the Linnean 

 trivial, which was restored by Huth in 1890 : see Ind. Kew. 

 Supp. i. 234, where, however, the identity of K. capensis with 

 K. rigida is not indicated. The name stands as : 



Knowltonia capensis (L.) Huth in Abb. & Vortr. Gesamt. 

 geb. Naturw. iii. 69 (1890). 



Adonis capensis L. Sp. PL 548 (1753). 



Knowltonia rigida Salisb. Prodr. 372 (1796). 



Ulmus (p. 391). The names (as species) assigned by Salisbury 

 to plants entered in Ait. Hort. Kew. (i. 319) as varieties of U. 

 campestris are not cited in the Cambridge Flora : they are 



PROCERA = U. campestris a vulgaris. 



angustifolia = ,, ,, /3 stricta. 



LATiFOLiA = „ ,, 7 latifolia. 



Of the last he says : " Procul dubio species est, in Yorkshire 

 passim vere spontanea." With regard to the second, if the 

 identity of Alton's variety with U. stricta Lindl. be accepted, it 

 would seem that U. angustifolia Salisb. would take precedence, 

 unless that be barred by U. angustifolia Moench Verz. Ansl. 

 Baeume, 137 (1785). The matter is one for workers at the genus 



* This principle, under the plea of " convenience," at one time found 

 countenance and defence at Kew : see Jouru. Bot. 1892, 53.
