Z. crepitans} — J. A. Wheldon. The variety crepitans is described in 
Bdnninghausen’s ‘ Prod. FI. Monast,’ p. 94. It has the capsule much 
longer than the calyx and dehisces elastically. Nothing is said about 
the ciliation of the carpels, etc. This is not the var. crepitayis. — G. C. 
Druce.

Melilotus coeruleus, L. On waste ground, Foss Islands, York, il 
August, 1889. — J. A. Wheldon. No, this is Trig 07 iella Besseria7ia i' 
Ser. in ‘DC. Prod.,’ ii. 181, which is kept distinct from Trigo 7 iella I 
c(zrulea, Ser. by Nyman, and by Ritter von Beck in ‘FI, Nied. Ost.’ )

Bess. ‘En. PI. Volhyn.’ 30 (1822). It is the Trigonella proawibens [

Rochel ‘PI. Rar. Banat.’ 51. t. 14. f. 31., 1828. In Reichb. ‘ Ic. FI. f 
Helv. et Germ.’ vol. xxii. p. 48, it is placed as variety laxiflora of T. \ 
cceruleus, Ser., from which it differs by its laxer head of flowers, by its ' 
much narrower leaves, which are more sharply denticulate, by the i 
narrower stipules, and by the beak of the fruit being straighten Of ) 
course, this is only a ballast casual. — G. C. Druce.
