Robinson and Greenman— Galapagos Flora. 143 
tetragonal, somewhat furrowed; internodes in specimens at hand 
considerably exceeding the leaves: the latter all opposite, petio- 
late, bipinnatifid, ovate or deltoid in outline, an inch or more in 
length; rhachis and segments very narrow, not a line in width, 
frequently curled, obtusish, so densely pubescent as to obscure 
completely the venation on both surfaces: inflorescence branched ; 
flowers small, in slender loose elongating spikes; central spike 
floriferous almost from base; the others more or less pedunculate ; 
bracts small, subulate, pubescent, $ to 3 the length of the calyx: 
the latter cylindrical, a line long, hirsute-pubescent on the outer 
surface, 5-ribbed; limb very shallowly and obtusely 5-toothed : 
corolla nearly twice as long as the calyx, unequally 5-lobed, 
pubescent in the throat; segments rounded at the apex: anthers 
unappendaged.—Collected on Duncan Island, August, 1891. A 
species of § Leptostachya and with much the habit of V. remota 
Benth., but dittering in pubescence and foliage. 
ALTERNANTHERA RIGIDA. Fruticose, copiously and densely 
branched: cortex light yellow, lucid: branches opposite, rigid, 
spreading or divaricate; internodes short, glabrous or nearly so: 
leaves opposite and proliferous in their lanate axils, very small, 
subulate, pungent, entire, smooth and green, about two lines in 
length, three-fourths line in breadth at the sessile base: spikes 
capitate, ovate or oblong, terminal upon the branchlets, 4 to 6 
lines in length, about 3 lines in diameter, bright white, slightly 
villous in the axils of the bracts, otherwise glabrous: bracts ovate, 
acute, two-thirds the length of the flower, white and scarious ; 
bractlets 2, ovate-lanceolate, somewhat falcate, equalling the 
calyx: stamineal tube about as long as the antheriferous pro- 
cesses; sterile processes none: stigmas 2, erect, obtuse.—Col- 
lected on James Island, on Orchilla Bay, August, 1891. <A note- 
worthy plant differing much in its erect firm habit and rigid 
subulate leaves from any species known to the writers. 
FRG@LICHIA JUNCEA. Stem woody below, profusely branched 
above; branches opposite, ascending, slender, terete, finely 
striate, puberulent or glabrous; internodes elongated: leaves 
reduced to minute scales, scarcely half line long, ovate, acute, 
scarious toward the edges: inflorescence terminal, loosely spicate, 
slender and flexuous, 1 to 24 inches long; flowers sessile, scattered, 
solitary in alternate bracts; the lowest stili more remote; bracts 
short, broader than long, obtuse, half line long, slightly if at all 
pubescent; bractlets broadly ovate, retuse, glabrous, scarious: 
calyx deeply 5-parted, in truit ovoid, ribbed, slightly compressed, 
firm in texture, dark colored, a line long; divisions oblong-lanceo- 
late, obtusish, scarious-margined: stamens included; anthers 
slightly exceeding the alternating obtusish sterile lobes of the 
Stamineal tube.—Collected on South Albemarle and Barrington 
Islands, July, 1891. A species with the juncoid habit of  nedi- 
caulis Hook. fil., but differing much in its elongated scattered 
inflorescence, glabrous bractlets, etc. A doubtiul and entirely 
sterile specimen was also collected on East Albemarle.
