Dod. I have found the variety in fair quantity occurring intermixed 
with the type but conspicuously distinct from it at Staithes, N. Yorks. 
I do not think much importance should be attached to a glabrous, or 
nearly glabrous state of a plant which does not differ in any other 
particular, but it seems more noteworthy when the two forms grow in 
the same locality under precisely similar conditions than when they 
occur in different habitats. — J. G. 
Sisymbrium offtcinarum Erysimum , Crantz ; var. leiocarpon. On 
waste ground near the beach at Ullapool, West Ross, July, 1893. 
This was a new species to the county — the variety I had not previously 
found in Britain, although I have long been looking out for it, I 
gathered it some years ago at Meran in Austria. At Ullapool it was 
the prevailing form, but at Jeantown, in the same county, the type, 
which has pubescent siliquas, alone occurred. — G. Claridge Druce. 
I cannot imagine why Mr. Druce employs Crantz’s clumsy trinomial 
name for the species.— J. G. 
Erysimum repandum , Linn. Garden, Birstal Hill, Leicester, 
July, 1893. During the last few years this plant has become 
quite naturalized in my garden as an abundant weed. The 
difference between the stellate hairs of the stem and those of the 
leaves is very noticeable. The former having two points directed 
upward and downward, the latter with three or sometimes four points 
radiating in the usual stellate manner. What are the precise characters 
by which this is distinguished from E. cheirantiioides ? — F. T. Mott. 
Why not ordinary E. cheiranthoides ? It does not in the least resemble 
E. repandum which, apart from the usually conspicuously repand- 
dentate leaves, has a short fruitstalk as thick as the fruit itself, and 
has the mature pods spreading at almost a right angle with the stem. —

Brassica Erucaslrum , Vill. Railway bank, Milverton, Warwick- 
shire, Aug. 1893. — H. Bromwich. “ Mr. Bromwich’s plant is not 
Brassica Erucastrum , Vill .= Erucastrum oblusangulum, Rchb. It is 
Eruca sativa , Lam., and as the seeds are arranged semi-biserially I 
suppose it will rank under E. longirostris , Uechtritz. In Buser’s 
‘ Supplementum ’ to Boissier’s ‘Flora Orientalis,’ page 66, there is 
the following remark under E. sativa : — “ Ab hac specie cl. Uechtritz 
(‘Gvst. Bot. Zeit.’ 1874, p. 133) distinguit E. longirostrem ob petala 
angustiora, siliquas angustiores rostro fructum icquante vel superante, 
semina obscuris biseriata, etc., huic praeter plantain ex Hispania 
australi Atticam et Sibth. tab. 646 adnumerans, sed ilke notae mihi non 
firmae videntur et transitus non desunt.” Reichenbach’s figure of the 
pod of E. sativa shows the seeds in two rows (‘ leones Florae Germ, 
et Helvet.’ Vol. 2, tab. lxxxii., f. 4,421.)” — Charles Bailey. The 
authority for the name of Brassica Erucastrum is Linn., not Vill. —
