one species.

As a genus Cystanthe is readily distinguished from Sprengelia by the corolla forming a closed conical cakjitra.

The stamens are hypogynous and persistent, with stout spreading filaments and two-lobed anthers. In bUUn 
and habit C. sprengelioides entirely resembles Sprengelia incamata, but the branches an marked with transverse 
scars where the leaves are inserted, and the flowers are collected into much denser, smaller terminal head-, llu 
stems vary from 3 inches to 3 feet high, and the leaves from J-l inch long; the alpine specimens have much 
broader, shorter, and blunter leaves, but Gunn remarks that mere elevation does not alter the character ot the
