﻿374 NEVIUSIA, A NEW GENUS OF ROSACE-ffi. 



I may now, therefore, be permitted to name the present genus in honor of the 

 discoverer. His name, however, is so nearly like that of the celebrated Eoman poet, 

 for whom (I presume) the learned Swedish mycologist has named his genus Ncevia, 

 that I must needs Latinize it in an unclassical, but not wholly unprecedented manner, 

 as follows : — 



NEVIUSIA, Nov. Gen. Rosacearum. 



Calyx ebracteolatus, patentissimus, 5-partitus, segmentis foliiformibus inciso-serratis 

 persistentibus. Corolla nulla. Stamina indefinita, disco tenui piano fundum calycis 

 vestiente pluriseriatim inserta : filamenta subulato-filiformia, post anthesin marces- 

 centia : antherse didymse. Ovaria 2 - 4, in fundo calycis sessilia : styli subterminales, 

 filiformes, apice introrsum stigmatosi. Ovulum unicum, pendulum, anatropum. 

 Achenia drupacea, epicarpio tenui carnoso, endocarpio crustaceo Isevi. Seminis testa 

 tenui-membranacea. Embryo in albumine parco carnoso inclusus, cotyledonibus ovali- 

 bus planis, radicula brevi supera accumbenti-inflexa. — Frutex alternifolius ; stipulis 

 parvis setaceo-subulatis liberis ; pedunculis filiforniibus ramulos breves terminantibus 

 solitariis paucisve fasciculatis. 



N. Alabamensis. — In prseruptis umbrosis prope Tuscaloosam Alabamee, ubi legit 

 Bom. JR. D. Nevms. 



Caulcs glabri, 2 - 5-pedales, recurvo-patentes, medulla ampla farcti. Ramuli gracUes, 



juniores cum foliis pedunculisque tenuiter puberuli. Folia ovata, nunc oblonga, 



rarius subcordata, membranacea, duplicato-serrata, vix incisa, recte penninervia, Isete 



viridia, 1 - 2^-pollicaria. Pedunculi nudi, floriferi semipollicari, fructiferi fere pollicaria. 



Calycis lobi patentissimi vel reflexi oblonga, 3 Im. longa, post anthesua paullo aucta 



et obovata, obtusa, supra medium argute inciso-serrata, nervoso-reticulata. Filamenta 



alba, calyce demum longiora, e basi crassiori filiformia : antherse breves, subintrorsse, 



biloculares, longitudiualiter dehiscentes. Ovaria gibboso-ovata, cano-sericea : styli 



glabelli, staminibus tequilongi, subpersistentes, apice leviter incrassato recurvo intus 



longitrorsum stigmatosi. Ovulum suturse ventrali prope apicem, ad insertionem styli 



respondenti, appensum. Achenia drupacea, oblique ovata, acuta, turgida, lineas 2 



longa, angulo interno basilari inserta ; sarcocarpio tenui sed manifesto ; putamine nee 



reticulate nee punctate. Semen pendulum, loculo confonne ; testa tenui albumini 



manifesto sed parco (embryonem omnino includenti) adh^rente. Cotyledones subcar- 



nosi, plani, late ovales, basi emarginati : radicula brevis versus hilum inflexa, cotyledo- 



num margini fere accumbens.
