232 New Species of Mexican Plants. [ZOE 
This plant is related to Grahamia of Chile, from which it is 
distinguished mainly by its bractless flowers, dissilient epicarp 
and incumbent cotyledons. The winged seeds and other char- 
acters are very different from those of 7alinopszs, which it re- 
sembles in the structure of its capsule.

Drymaria multiflora. Perennial, growing in clumps from 
stems rooting at the joints: stems erect, branching, 4 dm. high, 
striate, glabrous below, and above a portion of each joint glandu- 
lar-pubescent: leaves broadly ovate to orbicular, mucronate, 
attenuate at base into a petiole 2-6 mm. long; the blade 6-9 mm. 
long and wide, glabrous: stipules lanceolate: inflorescence termi-— 
nal and from the axils of the upper leaves, diffuse, many-flowered: 
bracts scarious, ovate-acuminate, with green midnerve: pedicels 
5-10 mm. long: sepals broadly ovate-acuminate with scarious 
margins: petals equalling the sepals, bifid nearly to the base into 
narrow divisions: seeds 4-10, echinate: stamens 5. 
From its description, D. grandiflora seems to be near this
