262 WILSON’S OBSERVATIONS, 
every part, the edge curling inwards, the posterior valve 
almost smooth. Upper lip of the corolla with jointed bristles, 
throat also hairy, and with glandular bristles. Tube of the 
calyx closed with bristles until the seed is ripe, the teeth 
also fringed. 
9. Melampyrum pratense. Scotland, July, 1827. Calya- 
teeth much longer than the tube, and very narrow, almost 
linear, curved upwards and appressed to the corolla and 
capsule. Capsule compressed. 
. 10. Melampyrum sylvaticum. Near Killin, July 24, 1827. 
Calyz-teeth longer than the tube, but not so long as in the 
last, than which they are much broader, spreading in the 
Jlowers, not turned upwards ; in the fruit they are slightly 
converging. Capsule not much compressed, veiny, with a 
long, tapering, compressed beak, Corolla shorter and more 
suddenly inflated at the mouth than in the last, and of a 
deeper yellow colour. Stem often covered with deflexed 
hairs. 
11. Orobanche major. Wales, June 17, 1826. Style as 
long as the upper lip of the corolla. Stamens rather shorter. 
-. 12. Orobanche minor. Ormeshead, J uly 10, 1826. Style 
and stamens much shorter than the upper lip of the corolla. 
Stamens sometimes nearly smooth. Stigma always yellow. 
Parasitical on Ulea europeus, but generally upon Ivy, as at 
Conway Castle, where it is plentiful. 
13. Subularia aquatica. Llyn y Cwn, June 30, 1828. 
Petals oblong. Anthers rounded and compressed, two-celled, 
the outer valve of each cell the largest, incurved, and lying 
contiguous to the capitate stigma, so that when the cells open 
the globular viscid pollen is immediately attached to the stigma. 
It is doubtful whether the impregnation is not accomplished 
previous to the expansion of the corolla; for when that takes 
place, the germen is usually so enlarged that the filaments 
are no longer of equal length with it, and the anthers are in 
this state closely applied to the side of the germen. The 
radicle and cotyledons in an immature state do very evi-
