each pedicel, sessile, lanceolate, doubly serrated, but less 
so than the leaves, nerved and veined. Pedicels nearly as 
long as the bracter. Calyx five-cleft,; segments erect, or 
somewhat spreading, pointed, and serrated. Corolla yellow, 
scarcely perfumed, tube (three-quarters of an inch long) 
twice as long as the calyx, round and slightly swollen, 
where it covers the germen, and in the situation of the 
stamens, distinctly five-sided between these two points, and 
in some degree above the last; throat naked ; lzmb spread- 
ing at a right angle, small (less than half an inch across, ) 
segments obcordato-rotund, crenate (or entire?). Anthers 
oblong, nearly sessile in the upper third of the tube. 
Stigma cup-shaped, included, but carried above the stamens. 
Style filiform. Germen globular, green. Ovules extremely 
numerous, ranged round the central receptacle, a slender 
process which is continued with the style, and may be easily 
unsheathed from the lower part of this. The outer side 
of the corolla, both sides of the calyx, the pedicels and 
scape, the bractee and leaves, particularly on the lower 
sides, are powdery. 
Wereceived, in 1825, a plant of this species from M. Orro, 
of Berlin, under the name of P. mvoluerata, marked 
« Egypt”, but it suffered so much on the way that it could 
not be preserved. The subject of the present article was 
raised from seed, communicated from the sameliberal quarter, 
dn 1826, and flowered in the beginning of the present 
month (March, 1828). The divided edge of the corolla 
seems the only deviation from the essential character of P. 
verticillata of Forsxaon, andthe analogy of other species, as 
P. prenitens, shews that this cannot be relied upon as a 
specific distinction. Granam. 
_I have compared the drawing of this interesting plant, 
kindly sent to me by Dr. Granam, with Vaut’s re of 
P. verticillata, in his Symbole Botanic, and 1 think there 
can be no doubt of the identity of the two. The plate 
of Vau1, evidently made after a dried specimen, has -the 
segments of the corolla not only entire but acute; 'Forsxaon 
himself describes them as being emarginate ; but Lenwann 
assures us that both the specimen of Vani and Forsxaon 
have them entire. os . 
Forskaor found the plant growing ‘by the sides of streams 
onthe mountain Kurma, in Arabia Felix.
