WILSON’S OBSERVATIONS, 811 
scale of the catkin, which may, perhaps, more properly be 
termed filaments than scales. Anthers of one cell with an 
external fissure.— Pollen globular. This is only a variety 
of the preceding. 
17. Aspidium aculeatum. Cultivated October, 1828. Seeds 
much smaller than in lobatum, of an angular shape, with a 
few transparent prominences—those of lobatum more regularly 
formed, almost round and covered with numerous narrow 
projecting points. 
18. Asplenium. Gen. Cuar. In some cases I find the 
Cover to separate at the outer edge, but such instances are 
not frequent. 
19. Lycopodium selaginoides. Aber, July 11, 1828. Seeds 
4 together, in aggregate masses, muricate, larger than in 
Selago.— They resist water and float on the surface. Capsule 
like that of Selago, but less compressed. The “lower cap- 
Sules containing 4 white globular bodies” are not ** placed 
one upon the other three,” but two upon two. Each consists 
of two valves of a triangular shape, or 3-lobed. The ‘globular 
bodies” are filled with an oily or mucilaginous matter. These 
Capsules ripen later than those containing the seeds.—Leaves 
imperfectly 5-rowed, the rows oblique or spiral. 
20. Lycopodium Selago. Aber, July 11, 1828. Leaves 
in 12 rows; but I suspect this to be variable. Seeds in 
aggregate masses of 4 each. "The upper whorl usually con- 
Sists (instead of capsules) of short branches or “ stalked 
anthers," surrounded by broader leaves than the rest; their 
‘Nature I cannot properly understand.— The leaves are keeled 
àt the back, in alternate whorls of 6 each. 
21. Lycopodium alpinum. Cwm Idwel, August 7, 1828. 
The barren branches usually spreading and fascicled, in a 
fan-shaped manner. The leaves not uniform, those at the 
Sides of the branch are largest and of rather different shape 
from the rest; those on the upper and lower side are scarcely 
keeled. Scales of the spikes in 6 rows. Capsule kidney- 
: Shaped, obscurely 3 or 5-lobed, or irregularly pitted in 
Various parts, the edge blunt and the sides flattened. Seeds
