Spec. Char., cSr. Stem suffruticosc, procumbent, branched. Branches as- 

 cending, cancsccntly tomcntose. Leaves oblong-lanceolate, acutish, rather 

 tomentose, grey above, and canescent beneatli, with the margins a little re- 

 volute. Stipules linear, awl-shaped, ciliated, a little longer tiian the petioles. 

 Calyx tomentose. Petals imbricate. (JJon'.s 2Iil/.,i. p. ."iiO.) A pretty 

 and curious plant, produced lioni the seed of 11. rroccum, that was fertilised 

 by the pollen of H. pulverulentum, in the Chelsea Botanic (Jarden, in the 

 year 18-J8. The seeds were self-sown in that year; in the year following, 

 the plants produced flowers, from May to the end of November. " The 

 flowers were very variable, some being of a bright yellow, and others, on the 

 same plant, and sometimes on the same branch, of a pale straw colour." 

 (Swecl.) It is a remarkably fast grower, an abundant flowerer, seeds freely, 

 and is quite hardy. Sweet says, " We have named it in compHment to our 

 respected friend Mr. William Anderson, the curator of the garden, to whom 

 we are obliged for the opportunity of making drawings of many rare species, 

 which we have not seen in any other collection."

Sjxc. Char., ^c. Stem .shrubby, branched. Branches smooth at bottom, but hoary-villous at top. 

 Leaves oblong lanceolate, with revolute in.irgins, tomentose on both surfaces ; under surface hoary, 

 upper surface yellowish green. Stipule.s linear, longer than t lie petiole*. Calyxes prufoundly sul- 

 cata, hardly pubescent, with elevated pilose nerves. {Ikm's Mill., i. p. .JIO.) A native of Spain, and 

 found on mountains in the kingdom of Valcntia. It \va.s introduced in 182o, producing its yellow 

 flowers in June and July. De Candolle doubts whether it is not only a variety of H. crficeum.

J'tirictifs. Two forms of this species are mentioned by De Candolle, viz. : H. f;. aculiuscnlum, the 



upper leaves of which are oblong, and rather acuminated, with the upper surface glaucescent ; 



and Ji. g. ohtiitiusculum, the upper leaves of which are oblong elliptical, bluntish, the np])er 



surface roughish and green. 



Sj^jCc. Char., cSr. Stem sufTruticose, branched. Branches ascendant, hoary- 

 tomentose, hispid at the top. Leaves ciliated on their margins, scarcely 

 revolute, tomentose on both surfaces ; under surface hoary, upper surface 

 greenish glaucous. Lower leaves round, the rest elliptic or lanceolate- 

 oblong. Stipules and bracteas jnibescent, green. Pedicels and calyxes 

 beset with white hairs. (Don's j\HI!., i. p. 311.) A suberect glaucous plant, 

 from Spain and Italy, in 1815; and producing its small pale yellow flowers 

 from June till August. It is a very desirable plant to keep in pots, for 

 turning out in the borders, or on rockwork, in spring, as it is rather tender, 

 and liable to damp offin the free soil, unless the situation is very dry and 

 warm. Plants were in the garilen of Robert Barclay, Esq., at Bury Hill, 

 near Dorking, in 1 829.

Spec. Char., Sfc. Stem suffruticose, branched. Branches elongated, ascendent, 

 somewhat canescent. Leaves lanceolate-oblong, usually with revolute 

 margins; under surface hoary-tomcntose, upi)er siu'face smoothish, green. 

 Calyxes furrowed, with elevated pilose nerves. (Don''s Mill., i. p. 311.) 

 A trailing plant, I ft. in heiglit, found on the mountains of Scotland, ami 

 also in Spain and France, producing its yellow flowers, with imbricate pe- 

 tals, in July.
