Nov. 4, 1923 COOK: PSEUDOPHOENIX INSIGNIS 407 
hilum rounded and prominent, broadly oboval, wider above than below, 4 
mm. long, 3 mm. broad, with an abruptly prominent conic-spiniform adhilum 
about 1 mm. high, distinctly truncate at apex, directed obliquely upward to 
meet a hardened, sharply triangular columella that projects into the fruit 
cavity, under the stigma; shell of endocarp somewhat thinner than in P. 
insignis but distinctly thicker than in P. linearis or in P. sargentii; seed sub- 
globose, nearly 9 mm. in diameter, with a very thin coating of flocculent 
material, or partially naked, exposing the light chestnut brown testa; impres- 
sions of the raphe and its two evenly curved branches very shallow, lined with 
delicate whitish strands. 
Type in the U. 8S. National Herbarium, no. 758,263, from the banks of 
a salt lake on Saona Island, Province of Seibo, Santo Domingo, collected 
December 9, 1909, by N. Taylor (no. 513). 
From the proportions and texture of the terminal and subterminal pinnae, 
as well as from the fruit and seed characters, it is evident that this species is 
very different from Pseudophoenix insignis. 
Pseudophoenix linearis Cook, sp. nov. 
Petiole at apex probably 1.5 to 2 em. wide, the rachis narrowed at the lowest 
group of pinnae; lateral wings of rachis very narrow, only 1 or 2 mm. wide; 
terminal portion of rachis very slender, less than 2 mm. thick, with a very 
fine, low median ridge, the upper pinnae rather remote, from 2 to 5 em. apart. 
Lowest pinnae very slender, in a close group of 4 to 6, the bases only 2 to 
4 mm. apart, very strongly complicate, with margins thickened and in con- 
tact, the margins and the midribs underneath with scattered dark-purplish 
fibrous scales; first pinna 33 cm. long by 2 mm. wide; second pinna 44 em. by 
5 mm., the apex very slender, remaining adherent 12 cm. from the apex of 
the third pinna; fifth pinna 72 em. by 7 mm.; third pinna from end 42 en. dy 
6 mm.; subterminal pinna 35 em. by 4 mm., the terminal subequal or slightly 
shorter, the rachis-bristle also subequal in length, 1 mm. or less in diameter; 
pinnae probably glaucous, the margins strongly thickened and the veinlets 
very close, usually with 2 veinlets on each side distinctly coarser than the 
others. 
Inflorescence with axis attaining about 2 cm. in width near the base, 
probably distinctly flattened, in the pressed specimen about 7 mm. thick, the 
branches subtended by persistent and triangular-acuminate bracts, carinate 
in the middle and distinctly veined; primary branch 35 cm. long, with 18 
secondary branches, the base naked for 8 em.; nine secondary branches with 
tertiaries, the lowest secondaries largest, attaining 12 cm. with 3 to 4 tertiaries 
3 to 5 em. long; no quaternary branches; the larger simple branches and simple 
ends of compound branches usually attaining 5 to 6 cm. 
Fruits about 1 cm. in diameter; double fruits 1.8 em.; pedicel slender, 4 
mm. long, with an expanded hollow base not attained by the everted petals; 
calyx rounded triangular, the angles rounded or minutely apiculate; filaments 
slender, scarcely broadened at the base, inserted on a thin, narrow ring; 
endocarp obovate, subglobose, 9 mm. in diameter, the wall about half as thick 
as in P. insignis, the hilum oval, the narrow end upward, less than 2 mm. 
long; margin of the shell above the hilum abruptly prominent, forming a low 
rounded tubercle (adhilum); seed subglobose, slightly pyriform, 8 mm. in 
diameter, with the floculent material of the other species mostly replaced by 
a delicate membrane covering a somewhat thicker and rougher testa, the 
raphe impressions rather narrow and blackish, the lower branches of the raphe 
very short.
