STANDLEY—STUDIES OF TROPICAL AMERICAN PHANEROGAMS. 441 
1. Watsonamra magnifica (Krause) Standley. 
Pentagonia magnifica Krause, Bot. Jahrb. Engler 40: 325. 1908. 
TYPE LOCALITY: Along the Rio Timbiqué, Colombia. 
Rance: Panama and Colombia. 
SPECIMENS EXAMINED: 
Cotompra: Along the Rio Timbiqué, March, 1889, Lehmann 8886, type col- 
lection (in herb. N. Y. Bot. Gard.). 
PaNAMA: Along the Rio Culebra, above Santa Isabel, Province of Colon, 
near sea level, Pittier 4158. 
It is impossible to be certain that the Panama specimen is of this species, 
since it is in fruit, and even the persistent calyces are mutilated so that their 
form can not be determined definitely. Krause describes the fruit as being 
perfectly spherical and 12 to 15 mm. in diameter. In the Panama plant 
it is ovoid-spherical, about 22 mm. in diameter and.24 to 28 mm. high, and 
finely striate longitudinally. The specimen of the type collection in the her- 
barium of the New York Botanical Garden has no fruit. The inflorescence is 
described as sessile, but in this specimen the peduncle is a centimeter long. 
In the plant from Panama the peduncles are even longer. It is very probable 
that, when the flowers of the latter are collected, it will be found to be an 
undescribed species. The single leaf of Mr. Pittier’s collection is 78 cm. long 
and 29 em. wide in the broadest part. 
2, Watsonamra wendlandi (Hook.) Kuntze, Rev. Gen. Pl. 1: 302. 1891. 
Pentagonia wendlandi Hook. Curtis’s Bot. Mag. 87: pl. 5230. 1861. 
Typr LOCALITY: The plant was described from cultivated specimens. Hooker 
states that it was brought by Wendland from some part of Central America. 
Hemsley’ gives the locality as Central Mexico, but this is probably a slip 
of the pen for Central America, since many such lapses are found in the Biologia. 
8. Watsonamra spathicalyx (Schum.) Kuntze, Rev. Gen. Pl. 1: 302. 1891. 
Pentagonia spathicalyx Schum. in Mart. Fl. Bras. 6°: 302. 1889. 
TYPE LOCALITY: In forests along the River Yapura and near Ega, State of 
Amazonas, northwestern Brazil. Type collected by Martius. 
Described from fruiting specimens; the corolla has not been seen. 
4. Watsonamra pubescens Standley, sp. nov. 
A small tree. 3 to 4 meters high; young branches thick and succulent, hirtel- 
lous; stipules not seen; petioles naked, 4 to 10 em. long, densely hirtellous with 
short hairs; leaf blades oval-obovate to elliptic-oval, 26 to 48 cm, long, 12 to 
23 em. wide, acute, rounded to acute at the base, densely pubescent on both 
surfaces with fine short spreading hairs, velvety to the touch, conspicuously 
veined, with 12 to 14 veins on each side, these branching near the margin; 
cymes subsessile or the peduncles 5 mm. long, few-flowered, the branches 
densely pubescent ; pedicels 2 or 3 mm. long, very stout; bracts oblong to broadly 
ovate, 10 to 15 mm. long, obtuse, finely nerved, appressed-pubescent on the 
outer surface; ovary 6 mm. long; calyx about 18 mm. long, the tube turbinafe, 
densely pubescent with appressed hairs, the lobes rounded at the apex, spar- 
ingly pubescent on the outer surface, the tube glandular within; corolla tube 
slenderly cylindric, 25 mm. long, 3.5 mm. in diameter, hirtellous outside, villous 
within, the lobes ovate, acute, 5 mm. long; stamens inserted 7 mm. above the 
base of the tube, the filaments slender, villous; style 18 mm. long, pilose above; 
immature fruit spherical, 12 to 14 mm. in diameter, crowned by the persistent 
and accrescent calyx, vertically striate, densely hirtellous.
