trichomes; midrib rather indistinct; flowers about 5 mm. broad, 
yellow; sepals 2 mm. long, triangular, sometimes broader than 
high, obtuse, hooded at the apex; petals small, 2 mm. long, ovate 
or oblong-obovate, obtuse, marked with five or seven nerves; 
stamens eleven or twelve; pisti] 2 mm. long, three to four-cleft, 
the segments obovate or spatulate, well covered with stigmatic 
processes; capsule hemispheric or turbinate-hemispheric, 2-3 
mm. long, 5 mm. in diameter, surmounted by a conspicuous 
crown, developed from the edge of the calyx where the lid joins 
the capsule; lid flattish, not crested, sometimes slightly depressed 
in the center; seeds twenty to forty, cochleate, gray, covered 
with acute or acutish pyramidal papillae. 
Collected in September, 1894, just below the summit of Little 
Stone Mountain, De Kalb County, Georgia. It grows in com- 
pany with P. ~ilosa in shallow depressions which have become 
partially filled with a sandy soil by the disintegration of the 
granite. There is a great contrast between it and the last named 
species, the plants are usually stouter, less dense in habit and the 
stems and branches bright magenta, whilst those of P. pilosa are 
of a light or dark shade‘ of green. It is more closely allied to P. 
Zanceolata Engelm. of southern and western Texas, from which it 
differs in the smaller flowers, and the sessile or nearly sessile leaves. 
The leaves are also different in shape and are never acute. The 
petals are not like those of P. /anceolata, and unfold in cultivated 
specimens about eight o'clock in the morning. 
TWO SPECIES OF HIBISCUS. 
_ Dr. Gray, in revising this genus for the Synoptical Flora, and 
in the fifth edition of his Manual, merged Michaux’s H. granai- 
florus into H. lasiocarpus of Cavanilles. It is difficult to under- 
stand on what grounds he did this, as the two species are so strik- 
ingly dissimilar. A comparison of their diagnostic characters 
is here given.
