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. 30.3.) 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. Lecheoides Dec. Prod.^ i. p. 269. 



Berivatim. From LechH, and eidos, appearance ; plants with the habit of some species of LechtvT. 



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, 1-celled. Seeds rufescent, small. Stems her- 

 baceous or suffruticose, ascendant or erect, usually dichotomous. Lower 

 leaves opposite, cauhne ones alternate, feather-nerved, on short footstalks 

 or sessile, without stipules. (Bon'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-fiowered. Flowers small, crowded. 



n. 16. H. coRYMBo^suM Michx. The covymhose-floivered Heliantheraum, or 



Sun Rose. 



Identification. Michx. Fl. Bor. Amer., 1. p. 307. ; Don's Mill., 1. p. 303. 



Spec. Char., S;c. Suffruticose, branched, erect. Branches dichotomous, rather pubescent, some- 

 what toraentosely 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 Mill., 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 to the 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.

Spec. Char., Sfc. Suffiniticose, 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. 

 (Doll's Mill., 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 1 ft. 

 in height, and producing very small or apetalous 

 flowers, in July and August. Mi-. Sweet remarks that all the species be- 

 longing to this section (hecheoides), when they flower in the spring and 

 early in the summer, produce flowers with petals ; whereas, when they
