A further study of this plant, in connection with that de- scribed next below, leaves me very doubtful about its affinity ’ New Speciges or SourH AMERICAN PLANTS 59 with Clusia. It has 6 to 7 or 8 ovarian cells, each containing a number of horizontal pendulous ovules, and the plant has all the habit of Clusia, but the carpels taper into triangular-lance- olate styles with terminal, peltate, concave stigmas, the styles in the young fruit state becoming erect or sub-erect. It can belong to no other described genus than Clusia, but I believe it to be distinct from that. In the absence of flowers, I can do no more than suggest this view. All the above remarks apply to the following. Clusia (?) ternstroemioides. Glabrous, the branchlets short, stout but weak, recurved, leafy at the summit. Leaves 4 to 6 cm. long, 2 to 5 cm. broad, oblanceolate, tapering into a very short winged and lightly keeled petiole and with rounded summit, thick and coriaceous, the midrib and about twenty pairs of secondaries sharply prominent beneath, very slightly so above.

The fruit is 2 cm. long, and 1.5 cm. broad, inclusive of the expanded wings, the body 9 mm. long, elliptical, with the summit emarginate, glabrous, the spikes shorter than their leaves, recurved. The flowering specimen is the type. Of 883, Mr. Smith says “A high vine, rare in dry forest not far from sea-level.

The fruits are 2 cm. long, by 1 cm. broad, inclusive of the wings, elliptical, emarginate, the body 5 mm. broad. Of this, Smith says ‘collected in a ravine near the seashore, Playa Brava, February 10.” Another specimen bearing the same number, but collected near Mamatoca, August 29, and here designated as 885-a, has the leaves oval, all shortly and bluntly pointed, bears lateral panicles, the petals longer and more unguiculate and the fila- ments stouter and rather shorter.

Glabrous; apparently perennial, the stems diffusely branch- ed, the branches ascending, reaching 2.5 dm. in length, at first very slender, becoming rather stout and very leafy, sharply angled, the internodes mostly about I to 1.5 cm. long.

Smith, Colombia, No. 528 pp.) Very near Lehmann’s 933, but the disk-corollas of the latter are little more than half as long and of different shape, and much shorter than the pappus. Species near P. diffusa H. & A. Pectis densa. Glabrous, the stems diffusely spreading, the foliage densely matted, the inflorescence abundant.

Local and rather rare in open lands. An infusion of the: plant used as a febri- fuge.’’ (Herbert H.

Mr. Smith sends another specimen under same number but with different locality and date and with leaves shorter but twice as broad. Of this he says “‘A broad-leaved form collected near Cacagualito, 1,500 feet, December 26.
