KEY TO THE SPECIES, 
Sepals’ free at base of fruit; leaves elliptic-ovate, abruptly 
acuminate, with thick salient nerves __-_-_-_ ~~ ~_________ 1. LH. calyculata, 
Calyx concrescent with fruit: leaves lanceolate, finely nerved_ 2. 1. collinsii. 
1. Eschweilera (Eueschweilera) calyculata DPittier, sp. nov. PLaTes I, II. 
A tree 8 to 15 meters high and up to about 40 cm. in diameter, with elongated 
crown; branchlets grayish, verrucose; leaves varying from 10 to 35 cm. long, 
and 4 to 12 cm. broad, glabrous, entire with slightly revolute margin, paler 
beneath, the petioles thick, 2 cm. long, blackish, the blades  elliptic-oblong, 
broadly acute or rounded at base, rounded and abruptly acuminate at tip, the 
main and secondary nerves very salient underneath and the latter indicated on 
the upper face by a corresponding depression, these nerves rather distant, more so 
at the middle of the blade, 11 to 12 pairs on each leaf, arched and anastomosed 
together along the margin; the intermediary venules also richly anastomosed, 
showing a fine prominent net on both faces, although more marked below; 
‘raceme terminal, or sometimes axillar, with numerous alternate flowers, the 
rachis not angulose, more or less verrucose; flowers rather large, pale yellow, 
caducous; pedicels 1 to 2 mm, long; sepals ovate, coriaceous, verrucose without, 
longitudinally striate within, with a thin, sublobulate margin, 5 mm. in length 
and breadth, but twice as large in fruit; petals about 20 mm. long, 8 mm. broad, 
obovate; androphorum large; ovary 2-celled; style 1 to 2 mm, long, conical; 
pyxidium 7 cm. in diameter and about 6 ecm. high, depressed-globose, thin- 
walled, rather smooth, with persistent sepals becoming twice larger than in 
flower, the interzonary band 3 cm. broad; seeds 3 to 5 in each cell. 
Forests between Port Limon and Moin, H, Pittier, September, 1899, flowers 
(Instituto fisico-geogriéfico de Costa Rica, no. 16008; U. S. National Herbarium 
no. 578009, type); clearings around Rio Hondo, H. VPittier, May, 1902, photo- 
graphs only (U.S. National Herbarium). 
Plate II is one-half natural size. 
Not infrequent on the Atlantic coastal plain at elevations up to 100 meters. 
2. Eschweilera (Chytroma?) collinsii Pittier, sp.nov. DPrare III. Ficure 1. 
Rranchlets gray, obscurely striate longitudinally ; petioles 1 cm. long, deeply 
canaliculate; leaf blade 19 cm. long, 5.5 cm. broad, smooth, lanceolate, broadly 
cuneate at base, narrowing insensibly into a long tip, shiny above, paler under- 
neath; main secondary nerves very salient beneath, numerous, close together, 
running in an almost straight line to the marginal zone, where they merge into 
each other; intermediary nervules also straight, shorter; margin distinctly 
crenato-* uvuate, the sinuses often marked by a black spot; racemes large, with 
alternat +, deciduous branchlets, bearing 15 to 20 alternate flowers, these also all 
caducous except the terminal one on the last branchlet, the main and secondary 
rachis gray, longitudinally striate and covered with numerous brown, verru- 
cose excrescences : pedicels 1 to 2 mm. long: flowers not seen; pyxidium termi- 
nal on last branchlet of raceme, 10 cm. in diameter, the interzonary band 4 em. 
tius had personally given a more accurate description of his genus, in the fol- 
lowing terms: “Genus Eschweilerae non iis innititur characteribus, quos 
Clarissimus De Candolle indicavit, sed ita erit constituendum: Lobi calycis 
4-6. Petala 4. Ligula uti in Lecythide. Ovarium bi-loculare, ovulis sub 20 
adscendentibus. Stylus rectus. Pyxidium lignoso-coriaceum, operculo deciduo, 
tandem uniloculare. Semina abortu ovulorum subquatuor obovata vel oblonga, 
erecta, pulpae immersa.” (Flora 2: Beibl. 89 1837.) The type species of the 
genus is Lschiceilera parvifolia Mart., from Brazil.
