the form of the flowers is so different from that of Hippotis, Som- 
mera, Watsonamra, or Tammsia, that the Costa Rican plant must 
become the type of a new genus. 
NOTHOPHLEBIA Standley, gen. nov. 
Tree with large opposite leaves, these petiolate, the blades leathery, entire, 
nearly glabrous, the leaf tissue finely lineolate between the veins; stipules 
large, distinct; flowers bracteate, rather large, in axillary many-flowered pe- 
dunculate cymes; calyx tube campanulate, as broad as long, very obscurely 
5-lobed, the margins faintly crenulate, naked within; corolla funnelform, the 
tube gradually widening upward, the 5 lobes valvate, much shorter than the 
tube, leathery; stamens 5, inserted near the base of the tube, the filaments 
slender, flexuous, unequal, pilose at the base, the anthers introrse, oblong, 
‘attached near the base, obtuse at the apex, caudate at the base, included; disk 
cupulate, 5-lobed; ovary 2-celled, the ovules numerous, compressed, inserted on 
elongated placentz adnate to the septum; style slender; stigmas oblong or 
lanceolate. 
Nothophlebia is most nearly related to Wdatsonamra, but it differs decidedly 
in the form of the calyx, that genus having a tubular and conspicuously 
toothed calyx or a tubular-campanulate and deeply lobed one. The corollas 
are very different in the two, the tube being cylindric in Watsonamra and 
obeonic in Nothophlebia. 
The name refers to the striz of the leaves, which falsely appear to be a part 
of the venation. 
Nothophlebia costaricensis Standley, sp. nov. 
Tree with a depressed crown; young branches stout and fleshy, obtusely 
quadrangular, glabrous; stipules 35 to 40 mm. leng, lanece-oblong, attenuate, 
sparsely strigillose-puberulent, glabrous within; petioles stout, 40 to 55 mm. 
long, nearly glabrous, sparingly tuberculate near the base; leaf blades oval or 
obovate-oval, about 33 cm. long and 17 cm. wide, obtuse, acuminate at the base, 
leathery, glabrous, or very obscurely pubescent upon the veins beneath with 
appressed hairs, the veins prominent, about 12 on each side, dichotomous 
near the margin; cymes many-flowered, loosely branched, the branches 
minutely puberulent and tuberculate, the peduncle 2 cm. long and the 
secondary branches of about the same length; pedicels T mm. long or legs, 
some of the flowers sessile; bractlets at the base of the flowers subulate, 2 mm. 
long; ovary turbinate,'4 mm. long, strigillose; calyx 4 to 5 mm. long and of 
about the same diameter, minutely puberulent outside, glabrous within; corolla 
tube 2 cm. long, 3.5 mm. thick at the base, expanding to & or 9 mm. in the 
throat, glabrous outside near the base, puberulont above, glabrous within except 
at the point of insertion of the stamens, there pilose; corolla lobes spreading, 
ovate, acute or acutish, 4 to 5 mm. long, densely puberulent outside, glabrous 
within or nearly so; filaments inserted 2 mm. above the base of the tube, 9 to 
10 mm. long; anthers 2.5 long; style 1 cm. long, the stigmas about 2 mm. 
long. 
Type in the U. 8. National Herbarium, no. 578472, collected on Collines de 
Moin, Atlantic coastal belt, Costa Rica, November, 1899, by H. Pittier (Inst. 
Fis. Geogr. Costa Rica, no. 16024). 
Only a few bracts are present upon the inflorescence, showing that they are 
early deciduous. There is no indication that any are ever present except at the 
base of the ovary or pedicel.
