REVISION OF THE FLOURENSIA.

By S. F. BLAKE.

INTRODUCTION.

, The genus Flouremia, established by De Candolle 1 in 1836 to , include a Chilean described by Molina as a Heliamhus and three new species, was divided by him into two groups one, Chilean, including the two radiate species F. thurifera (Mol.) DC., with a variety angustifolia DC., and F. corymbosa (a true Viguiera); the other, Mexican, with the two discoid species F. laurifolia and F. cemua, both based on Berlandier's collections. In the Genera Plan­ tarum of Bentham and Hooker' Flourensia was included under Helian­ thus 'with some mention of its peculiarities, while F. corymlJOsa was relegated to Viguiera. In 1883 Gray' discussed the genus, consid­ ering the discoid species typical, suggesting that F. thurifera might be - included as a section" under Bertero & Colla's name (not Cassini's) of Dio sen ted in the Berlin Herbarium by an authentic but very poor speci· men, is a Viguiera apparently identical with V. g'illiesii (Hook. & Arn.) Hieron. In 1891 Philippi' published Heliamhus atacamensis, referred to Flourensia by Reiche' in 1905, and in 1895 " several new species ------. I Prodr. 6: 592. 1836. • Gen. PI. 2: 376. 1873. • Proc.

of Helwnth,ru, of which four were referred as species or varieties to • F'louremia by Reiche in 1905. Only H. ataca11U<1I8'i8 has been exam­ ined by the writer, but from description it is clear that all Philippi's species belong to Viguiera, or perhaps in part to true HelwnthU8; certainly none is referable to Floure1l8w. The genus F10'Ure1l8w, here limited as it was redefined by the writer II in 1913, includes 23 species, nine Mexican, of which one enters the southwestern United States, the other 14 native in the Andes from central Peru to Chile and the Province of C6rdoba in Argentino.. All are low, more or less resinous, alternate-leaved shrubs, with few-seriate involucres of herbaceous or only basally indnrate • phyllaries, thickened or more or less compressed achenes, villous at least on the margin, and persistent or rarely deciduous pappus of two often trifid awns and rarely a rew narroW acute squamellae. The present revision, begun at the Berlin Herbarium in the Bummer of 1914, has been completed by a study of the material in the British Museum, the Kew Herbarium, the Gray Herbarium, and the United States National Herbarium, in the course of which it has been possible to examine types of all the species with the exception of the original Hclianth1l8 thurifer of Molina, material of which is probably no longer in existence.
