220 SIR JOHN LUBBOCK ON STIPULES, 
Stipules rather large, lanceolate-subulate, hairy. Otherwise like 
Helianthemum vulgare. 
In H. lavandulefolium the leaves are narrowly oblong, obtuse, 
thinly stellately hairy above, densely felted beneath; otherwise 
like H. vulgare. Stipules small, subulate. 
H. rosmarinifolium ? has its leaves 1 in. to 14 in. long, oblong» 
obtuse, thinly stellately hairy above, densely felted and hoary 
beneath; otherwise like H. vulgare. Stipules long, subulate, 
acute, 
In all these species the petiole tapers more or less towards 
the base. 
Now let us turn to the species without stipules. Beginning 
with H. elandicum (fig. 2), the plant is dwarf and prostrate. The 
Fig. 2. 
Shoot of Helianthemum ælandicum. Slightly enlarged. 
leaves are opposite, exstipulate, oblanceolate or spathulate, taper- 
ing to a broad base, sessile, often but not always distinctly three- 
nerved, ciliate, especially at the base, and hairy on the midrib 
beneath, sheathing the apical bud very closely in the young state. 
H. lasianthum is a suberect and shrubby species. The leaves 
are oblanceolate, or spathulate, obtuse, undulate at the margin, 
tapering to a short petiole which is distinctly widened at the very 
base, and sheathing the bud in a young state, stellately pubescent 
above and densely felted beneath. 
H. ocymoides has its leaves oval obtuse, tapering into a petiole 
which is grooved above, dilated and sheathing the bud by its 
base, hoary, and densely felted with stellate pubescence on both 
surfaces. 
H. formosum is a shrub of similar habit to the last. Its leaves 
are cblanceolate, obtuse, or the larger ones oblong, three-nerved, 
densely felted on both surfaces and hoary, with stellate tomentum, 
undulate at the margin, tapering into a broad flat petiole, which
