ad 0.5 mm. longae, marginibus laevibus nee ciliolatis;
stylo crifido.
Type in herb. Chi. Nat. Hist. Mus., isotype in herb. Iowa State

Allied to L. Spruce* H. Pfeiffer and L. guianensis Nees, but
differing from them in the bifid and aristate glumes and in the characters
of the achene.
Lagenocarpus glomerulatus Gilly, sp. nov.
Subcaespitosa,caulibus brevibus, vaginis persistentibus reticulatofibratis
tecta; folia 6.5 dm. longa et ad 7 mm. lata linearia plana vel
bicarinata ad apicem glabra vel hispidulosa; culmi floriferi triangulari
glabri, cum inflorescentia ad 6 dm. alti; inflorescentia interrupta,
bracteae paniculis secundarius subtendentes cum vaginae breves et
laminae vaginorum 10- a 30-plo longioribus; spiculae masculae 2.5
mm. longae glomerulatae, 7-15 aggregatae conjunctim in paniculis
inferioribus laxe confertae, glumis vacuis 2-4, ovatis vel lanceolatoovatis
mucronatis glabris, margine ciliolatis exceptis, glumis staminibus
6-15, lanceolatis vel lineato-lanceolatis acutis vel erosis et
ciliolatis ad apicem; antherae ad 1.2 mm. longae; spiculae foemineae
uniflorae ad 3.5 mm. longae, solitariae vel geminae in paniculis

mm. diara. et cum rostro laevi stramineo 3.5 mm. longum; rostro

squamellae hypogynae late orbiculares vel quadrangulares ad

de Kavanayen and base of Ptari-tepuf, state of Bolivar, alt. 1220 m.,

A very distinctive species apparently related, at least in the
characters of the achene and the staminate spikelets, to L. rigidus
Nees of eastern Brazil, but differing markedly from that species in
foliage and type of inflorescence.
Lagenocarpus sabanensis Gilly, sp. nov.
Subcaespitosa, caulibus brevibus lignosis, vaginis persistentibus
laceratis tecta; folia linearia plana ad 4 dm. longa et 5 mm. lata,
dense minute pubescentia supra et infra, marginibus minute hispiduloscabratis;
culmi floriferi canaliculati dense adpresso-villosuli, cum
