New Species of South American Plants 155 



acute; coarsely dentate, thin, pale-green, the 3 strong ribs 

 continued into the petiole, the slender venation coarsely reti- 

 culate and not conspicuous. Heads short or long-peduncled, 

 the peduncles slender. Involucre campanulate, in flower about 

 12 mm. long and broad, as pressed, the scales in about three 

 series^ with the outer shorter, lanceolate and acuminate, but 

 obtusish, strongly 3-nerved, the nerves green. Exserted por- 

 tion of rays about as long as the involucre. Disk-scales a half 

 longer than the akene, ovate, acute, scarious, strongly keeled, 

 ciliate toward the summit. Akene 6 mm. long, -strongly com- 

 pressed, thinly margined, very sparsely pilose, obovate. Pappus 

 of 2 slender setae two-thirds the length of the akene, with some 

 very small ones interposed. Corolla about as long as the akene, 

 the stout cylindrical base about a fourth of the length and half 

 as wide as the abruptly expanded portion, the short, lanceolate 

 acute teeth strongly recurved. Style slightly exserted, the 

 acute branches strongly recurved. Stamens much shorter 

 than the corolla, the anther-bases produced into acute mucros. 



" A shrub i to 3 feet high, on seashore on dry rocks and 

 occasionally in sand at Playa Brava, November." (Herbert 

 H. Smith, Colombia, No. 594.) 

 Galea (Eucalea) congesta. 



Roughish-hairy throughout, the leaves scabrous on both 

 surfaces. Branchlets erect, leafy, reddish-brown, about 4- 

 angled, the intemodes only about half the length of their leaves. 

 Petioles about 6 mm. long, broad, channelled above, th; blades 

 3 to 5 cm. long, 2 to 4 cm. broad, ovate, the base rounded and 

 slightly produced into the petiole, acuminate, obsoletely ser- 

 rate, revolute, thick, strongly bullate, the venation strongly 

 reticulate and very prominent underneath. Heads in short- 

 peduncled, densely flowered axillary umbels or corymbs, the 

 heads 2 or 3 times the length of their peduncles, 6 or 7 mm. long 

 and about half as wide, the narrowly turbinate involucres 

 nearly equaling the disk, its scales in 7 or 8 series, the outer- 

 most very small, ovate, green, thick, the others successively 

 longer and relatively narrower, the innermost linear-lanceolate, 

 scarious with green middle portion, all appressed and obtuse. 

 Rays wanting. Akene about i mm. long, two- thirds the length 

 of the pappus, narrowly turbinate, striate, minutely hispid, 

 the pappus unequal, in a single series with a few minute setae 

 between, distinct to the base, linear, acuminate but not finely 

 attenuate, serrate, extending above the base of the corolla-lobes. 

 Tube of corolla cylindric, about as long as the limb, which is 

 parted to the base; the lobes linear, acutish, strongly recurved. 

 Anthers about equaling the corolla lobes, their basal lobes 

 acute. Receptacle elongated, nodose, its scales broadly obo- 

 vate, abruptly acuminate, lacerate, extending about to the 

 base' of the corolla lobes.
