SIPHONYCHIA CORYMBOSA.
Perennial, stoutish, the foliage pubescent with recurved hairs. Stem branched at the base, the branches tufted, 1-3 dm. tall, erect or ascending, olive-green or brownish, forking, especially above, ribbed, topped by the corymbosely disposed cymes ; leaves oblan ceolate to oblong-oblanceolate, .5-1.5 cm. long, acutish, ciliate, sessile ; stipules ovate, silvery, long-acuminate ; inflorescence sil very; calyx 2-2.2 mm. long, pubescent at the base, the segments oblong or ovate-oblong, white, longer than the tube, obtuse, con cave, slightly hooded at the apex ; stamens included ; style ex serted ; utricle ovoid, i mm. long.
The original specimens were collected by Professor L. M.
Underwood on Ship Island, on the coast of Mississippi, in June, 1896.
Sipkonychia coginbosa is most closely allied to Siphonychia ercaa, which it simulates in habit. The characteristic difference in ap pearance between the two species is in the foliage, that of S. crecta being glaucous, while that of the new species is clothed with a pubescence consisting of short recurved hairs ; the inflores cence of Sipkonychia coymbosa is more lax ; the calyx furnishes good distinctive characters : that of the new species is shorter and stouter, the segments oblong, with converging tips, instead of lanceolate, with erect tips, as in that of S. crecia.
