together in the axils: calyx-lobes lanceolate, acute, mucronate, 1 
to 14 lines long, about equalling the corolla: fruit with scattered 
grayish pubescence.—Collected on Indefatigable Island, south of 
Conway Bay, August, 1891. | 
The three species of Borreria here described were distributed 
as pepsin Baurii, S. Galapageia, and S. Pacifica, respec- 
tively. 
ERIGERON TENUIFOLIUS Hook. fil.? Specimens corresponding 
in most essential characters with Hooker’s description (Enum. PI. 
Galap., Trans. Linn. Soc. xx, 207), were secured on South Albe- 
marle Island, July, 1891. The leaves, however, are 14 to 3 inches 
long and $ to 1 line broad, being accordingly nearly twice as large 
as in the type. Furthermore the tubes of the disk flowers are 
glabrous. Without a comparison with the type it is impossible 
to say whether the present plant is identical with it or represents 
a species new at least to the islands. 
An interesting but unfortunately sterile plant collected on 
Charles Island, is identical with the specimen of Andersson upon 
which it appears that Steetz based his description of Z. tenuifo- 
“ius in Andersson’s Om Galapagos-éarnes Veg. 68. It is to be 
regretted that the present specimens are too imperfect to show the 
true position of this problematic plant, although they show pretty 
clearly that it is distinct from Hooker’s species. 
ACANTHOSPERMUM LECOCARPOIDES. Pubescent throughout and 
probably viscid: leaves ovate-oblong, irregularly laciniate or shal- 
lowly pinnatifid, with obtusely toothed segments, rounded sinuses, 
and tapering base, slender-petioled, 2 to 4 inches long: peduncles 
solitary in the forks, slender, 2 inches long : heads three-fourths 
inch or more in breadth; outer involucral scales about 4, ovate, 
acuminate, serrate or entire, 3 or 4 lines long, pubescent upon 
both surfaces; rays yellow, about 5, elliptic-oblong, minutely 
3-toothed at apex: fruit (achene invested in inner bract) irregu- 
larly turbinate, somewhat compressed laterally, and developed 
dorsally, finely and densely pubescent and bearing near the sum- 
mit 4 or 5 slender spreading straight or somewhat hooked spines: 
style with slender and spirally recurved branches: disk-flowers 
about 30, glabrous, with filiform empty achene, slender tube, 
ampliate throat, and 5-cleft limb: style filiform, entire: anthers 
subsagittate at base: chaff 14 lines long, irregularly fringe-toothed 
at apex: disk conical.—Collected on Hood Island, July, 1891; 
said to be rare, at least upon this island. Although possessing 
all the important technical characters of the genus, this plant has 
more numerous disk-flowers than any hitherto known species. 
Both in this regard and in its outer involucre and foliage it bears 
a strong resemblance to Lecocarpus, a genus peculiar to the Gala- 
pagos Archipelago, doubtless nearly related, but with a very dif- 
ferent and characteristic fruit. 
Scatzs1a Bauru. Villous-pubescent: leaves pinnatisect to the 
middle, ovate in outline, acute, attenuate at the base, resinous- 
dotted, finely pubescent and slightly scabrous above, pubescent
