“Trunk low, spiny; frond simple, the petiole spiny; blade lanceolate in young plants, oblong in the adult, cuneate at the base and bifid at apex, the margin unequally erose, unarmed; rachis and primary veins spiny on both sides; spines bristle-like, narrowed at base, those of the petiole black, those of the blades fuscous.” “In the western part of the island of Puerto Rico, near the village of Yrurena, in swampy places on the margins of aboriginal forests at an altitude of 400 feet; collected by Wylder, 1827.” (Martius Hist. Palm. =3=: 281.) A specimen to which the above diagnosis would not be inapplicable was collected by Sintenis in the mountain forests near Maricao (no. 484). It was distributed from Berlin as a _Martinezia_, together with two other very young plants and a seed to which one of these was attached. The seed evidently did not come from a cocoid palm but together with the young seedlings may belong to _Acrista_. The large spiny plant is probably a young specimen of _Curima_, and should these suggestions prove to be correct the specific name _acanthophylla_ must be transferred to this genus though whether it will replace _colophylla_ or not is not to be determined until it can be ascertained that the Maricao species is the same as that here described from Bayamon. BACTRIS PAVONIANA Martius, Palm. Orbign. 70 “Frond pinnate, rachis with rather long spines and black bristles: linear acuminate, about equally distant, the terminal united, setose-ciliate, glaucous below and with a sparse whitish down.” “Puerto Rico; Pavon.” (Martius, Hist. Pal. =3=: 282.) Grisebach has reported this species from Antigua and has redescribed it as follows, presumably from the Antigua specimens. “‘Trunk low’; _leaves pinnatisect: segments numerous, grass-like, linear-acuminate_ or the uppermost broader by cohesion, glaucous and minutely puberulous or glabrescent beneath, approximate, subequidistant, reduplicate at the base: _rachis armed with very long black prickles_ and rare bristles, keeled above.—Flowers unknown; leaf segments (in our specimens, which are cut off, perhaps about the middle of the rachis) more than 30–jugal, 3‴–6‴ distant, 12″–8″ long, 4‴–2‴ broad, superior gradually shorter, the uppermost cohering ones sometimes 6‴–8‴ broad: prickles scattered or clustered, slender, the greatest 2″ long. Hab. Antigua: _Wullschl._, Blubber valley; [Portorico].” (Grisebach, Fl. Brit. W. I., 520. 1864.) =Curima= gen. nov. Trunk rather slender, internodes armed with scattered slender spines. Leaves and inflorescence also spiny, especially on the proximal parts. Pinnae numerous, strap-shaped, praemorse-truncate, imperfectly separated near the ends of the leaves. Inflorescence rather slender, once-branched; pistillate flowers mostly located near the bases of the branches. Fruit drupaceous, exocarp fleshy, not fibrous; foramina peripheral.
