« 15. H. watimiro‘tium Willd. The Sea-Purslane-leaved Helianthemum, 
or Sun Rose. 
Identification. Willd. Enum., 569. ; Swt. Cist., t.4.; Don’s Mill., i, p. 303. 
Synonymes. Cistus halimifdlius Lin. Sp., 738. ; Cistus folio Halimi, i., Clus. Hist., 1. p.71. 
ngraving. Swt. Cist., t. 4. 
Spec. Char., §c. Erect, branched. Branches leprously white at the top, as 
well as the leaves, on both surfaces. Leaves on very short footstalks, ovate- 
oblong, tapering to the base. Peduncles long, branched, somewhat panicled, 
leprously white. Calyx leprous, 5-sepaled, two outer ones very narrow, 
linear. (Don’s Mill., 1. p. 303.) An erect bush, growing to the height of 
3 ft.; found in Spain and Portugal by the sea-side, and cultivated in Eng- 
land since 1656; producing beautiful yellow flowers, spotless, or each marked 
with a small dark bloody spot at the base, in July and August. It is some- 
what tender during winter, but grows freely during summer, and ripens 
abundance of seeds. Plants of it were in Colvill’s Nursery in 1826. De 
Candolle notices a variety with obtuse leaves. 
§ ii. Lechedides Dec. Prod., i. p. 269. 
Derivation. From Lechéa, and eidos, appearance ; plants with the habit of some species of Lechta. 
Sect. Char. Calyx 5-sepaled, 2 outer sepals narrow, linear, 3 inner ones 
acute, with scarious margins. Petals yellow. Style almost wanting, or 
very short, erect. Stigma large, capitate. Ovary triangular. Capsule 
smooth, shining, 3-valved, l-celled. Seeds rufescent, small. Stems her- 
baceous or suffruticose, ascendant or erect, usually dichotomous. Lower 
leaves opposite, cauline ones alternate, feather-nerved, on short footstalks 
or sessile, without stipules. (Don’s Mill., i. p. 303.) The species in- 
cluded in this section have generally very small flowers; and, as remarked 
below, their flowers are frequently apetalous. 
A. Peduncles many-flowered. Flowers small, crowded. 
» 16. H. corympBo‘sum Michx. The corymbose-flowered Helianthemum, or 
Sun Rose. 
Identification. Michx. Fl. Bor. Amer., 1. p. 307. ; Don’s Mill., 1. p. 303. 
Spec. Char., &c. Suffruticose, branched, erect. Branches dichotomous, rather pubescent, some- 
what tomentosely cinereous at the top. Cauline leaves alternate, oblong-lanceolate, bluntish ; 
under surface clothed with woolly tomentum ; upper leaves with revolute margins. Corymbs fas- 
tigiate, crowded. Calyx tomentosely hairy, canescent ; outer sepals linear, blunt ; inner ones ovate 
acute, somewhat shorter than the capsule. (Don’s Mili., i. p. 303.) This species is one of the few 
belonging to the order which are natives of America, having been found by Michaux in New 
Jersey and Georgia. It grows tothe height of about 1 ft., and produces its (?) yellow flowers in 
July and August. We are not aware of its having been introduced into England, 
« 17. H. cLomera‘tum Lag. The glomerate-flowered Helianthemum, or 
Sun Rose. 
Identification. Lag. in Litt. ; Swt. Cist., t.110.; Don’s Mill., 1. p. 303.

flowered Helianthemum. 69 
Engravings. Swt. Cist., t. 110.; and our jig. 69. 
Spec. Char., $c. Suftruticose, erect, somewhat dichoto- 
mous. Branches rather tomentosely cinereous. 
Leaves lanceolate-oblong, tapering to the base; under 
surface hoary. Racemes axillary or terminal, many- 
flowered, smaller than the leaves. Flowers glomerate. 
(Don's Miill., i. p. 303.) Found wild near Acapulco 
and Cimupan, in New Spain. Seeds of it were brought § 
to England from Mexico, by Mr. Bullock, in 1823. It 
is a low but erect undershrub, scarcely reaching | ft. 
in height, and producing very small or apetalous 
flowers, in July and August. Mr. Sweet remarks that all the species be- 
longing to this section (Lechedides), when they flower in the spring and 
early in the summer, produce flowers with petals; whereas, when they
