OF ARTS AND SCIENCES : OCTOBER 14, 1862. 51 



Nksogenes euphrasioides, a, DC. {Myoporumi euphrasioides, 

 Hook. & Arn.), which was collected upon several of the Coral Isl- 

 ands, — a plant with much the aspect of Hedeoma ptdegioides, or of 

 some Lythram, — proves to be no shrub, but probably an annual, and 

 no Myoporineous plant. The anthers are distinctly two-celled, and 

 the ovules are erect. Without doubt it is a true Verbenacea, but I 

 kjjow not any genus which it particularly approaches. The generic 

 character, as corrected and completed, is as follows : — 



Char. gen. Calyx obconicus, 10-nervis, 5-dentatus, dentibus tri- 

 angulatis, post anthesin auctis patentibus. Corolla bilabiata, labio 

 superiori bipartite, inferiori tripartito, lobis rotundatis consimilibus, 

 posticis paullo brevioribus. Stamina 4 fertilia, didynama, cum vestigio 

 filament! quinti : antherce biloculares, didym;©, loculis paullo divergenti- 

 bus (baud confluentibus) basi aristulatis. Discus hypogynus nullus. 

 Ovarium ovatum, biloculare, loculis uniovulatis : stylus terminalis, fili- 

 formis : stigma parvum indivisum. Ovula e basi loculi erecta, ana- 

 tropa. Drupa sicca, nucuraentacea, parva, calyce inclusa, epicarpio 

 tenuissimo, endocarpio crustaceo, bilocularis (vel dissepimento evanido 

 unilocularis), disperma vel abortu monosperma. Semen cylindraceum, 

 testa reticulata, albumine parco. Embryo teres : radicula infera coty- 

 ledonibus sequilonga. — Herba sesquipedalis, ut videtur annua, hirtello- 

 scabra, caulibus nunc basi lignescentibus, ramis foliosis ; foliis oppositis 

 parvulis ovatis basi angustatis in petiolum attenuatis integerrimis, in- 

 ferioribus quandoque subcrenatis ; floribus parvis in axillis saspissime 

 geminis ; pedicellis calyce brevioribus minutissime bibracteolatis mox 

 decurvis ; corolla caerulescente ?

The ordinal character in the Prodromus respecting the stamens, 

 " absque vestigio quinti superioris," disregards Brown's character, 

 " quandoque rudiraentum quinti, raro polliniferi." It may be indirectly 

 made out that Brown here refers to llyoporum, and I suspect that he 

 had a Sandwich Island representative of this group in view, in which 

 the stamens are really isomerous with the lobes of the corolla in all the 

 numerous flowers which I have been able to examine. This chai'acter 

 in M. Sandwicense, (which has escaped the notice of all preceding 

 observers, except, probably, of Brown, who must have had this plant 

 under examination,) along with the increase in the number of the cells 

 of the ovary, would fully warrant the establishment of a separate
