NOTE ON BARBAREA STRICTA 107 
Perhaps the best distinguishing mark of B. stricta is the 
apd of spreading hairs at the apex of the term the hairs 
most be. on the buds, and give a anded in- 
st same stage. The character appans a be osiaitasi, "but seems 
o have been overlooked except G. Blytt (Norges Flora, 
p. 969 (1876), Haandbog, P. 365 (1804)) and Oborny (Flora von 
Mahren u. osterr. Schlesien, p. 1182 
Other good distinotienh between. the two Rte in a living 
state are that the petals of B. stricta are suberect, or at most only 
patulous, whereas those of B. vulgaris are at ra spreading, and 
finally become more or less reflexed, as has been briefly noted by 
Mr. J. G. Baker (Journ. Bot. 1871, 213), who mentioned also the 
deeper colour of the petals in B. stricta; and that the foliage and 
stems of B. stricta are yellow-green, whereas those of B. vw aris 
is much more corymbose than that of B. vulgart 
The following ‘supplem entary diagnoses pte been drawn up 
from the mitra plants :— 
B. vunearis R. Br. Bud8 glabrous. Sepals 3-4 mm. long. 
Sheage Micra obovate, more or less distinctly retuse, 5-5-7 mm. 
2-3 mm. broad, yellow with a whitish claw, at first spread- 
ici finally mie or less Pamigea 
B. srricta Andrz. Buds hairy at apex. Sepals 2‘5-3 (rarely 
4) mm. long. Petals opin: spathulate, rounded, truncate or 
obscurely retuse, 3-5-5 mm. long, 1-15 mm. amy yellow all 
over, ascending, the posticous ones at length patulou 
Although it is an easy matter to identify B. sei in the 
living state, the fe cinder a of herbarium material is quite 
another matter, as the differences in colour and in the direction 
of the petals can no longer be observed, and ri) hairs on the 
sepals tend to fall off, or to be rubbed off. Hence we have had 
to rely entirely in some cases on such characters as the shape 
of the leaves and nature of the infructescence, which, though 
often decisive, are insufficient for the determination o 
specimens. 
With the exception of a single specimen from Japan and two 
from Canada, we have seen no extra-European mate rial of B. 
stricta. The Japanese specimen, which we cannot identify with 
certainty, owing to the imperfect preservation of the flowers, was 
collected at Sapporo, Prov. Tshikari, Hokkaido . and was com-
