Description
|
Small trees infrequently to 20 m. tall, with rather stout flexuose ferruginous- hirsutulous branches. Leaves broadly oblong-elliptic grading toward obovate or ovate, the apex abruptly and narrowly subcaudate-acuminate, the base predom- inantly more or less deeply cordate, infrequently broadly obtuse or rounded in young leaves, entire to indefinitely undulate-serrate toward the tip, 15-40 cm. long, 7-15 cm. broad, firmly membranaceous, more or less ferruginous-hirtellous, par- ticularly beneath, the petiole rather stout, 5-10 mm. long; stipules narrowly ovate-lanceolate, long-acuminate, 2-4 cm. long, densely sericeous. Staminate heads about 1.0-1.5 cm. in diameter, the peduncle about 1 cm. long. Pistillate heads superficially similar to the staminate with about 25-50 flowers. Fruiting heads oblate-ovoid, about 5-6 cm. broad, the achenes about 1 cm. long.

Note
|
The association of these plants with Aublet's name is made with some misgiv- ings. Perebea guianensis was excellently and unmistakably illustrated by Aublet, but it is doubtful whether the holotype exists at Paris, since Trecul apparently was not able to find it and my friend Dr. F. G. Meyer did not find an isotype at the British Museum. Dr. Meyer did find a staminate specimen, apparently of this species collected by Martin in 1804, a duplicate of which is now available not only at the British Museum (and presumably Paris?) but at the Missouri Botanical Garden. This sheet corresponds generally to those cited from Panama on the one hand and on the other to several collections from South America which, because they are now distributed under other names, I shall cite both in support of my interpretation and for the use of others: BRAZIL: Kru/off 4827, 704I, 7209, 8076, 835o, Ducke I22I (24-5-1940) PERU: Klug 27I9, R. C. Lorenz 32I0-all deposited in the herbarium of the Missouri Botanical Garden. For positive identi- fication fruiting specimens from Panama are necessary, and I must confess that some of the Panamanian sheets are noticeably more pubescent than these from Brazil and Peru.
