396 Mr. J. Miers on the Styracese, 



ments for nearly their whole length, as described by Prof. DeCan- 

 dollc, is a sexual, not a general character, 



.5. FOVEOLARIA. 



This genus was established by Ruiz and Pavon upon five 

 Peruvian species : of these, Prof. A. DeCandolle rejects four, 

 which he refers to Styrax {Strigilia)^ retaining only F. ferrU' 

 ginea; of the latter, an excellent figure is given in Delessert's 

 ^ Icones Selectee,' v. tab. 43, the detailed analysis of which, and 

 the description in the ^ Prodromus,' constitute all the knowledge 

 we have concerning it. As I have never seen a specimen, I 

 cannot form a decided opinion of the validity of the genus. Like 

 Pamphilia, it is distinguishable from Strigilia in its ovary having 

 only a solitary erect ovule in each pseudo-cell ; but it difiers again 

 from Pamphilia in having, like Strigilia, 10 stamens. Its chief 

 difi'erential character, that of its monadelphous stamens, as I 

 have suggested in Pamphilia, is probably only a sexual feature, 

 and not more than a lax agglutination of the margins of the fila- 

 ments : that of its free ovary is common to Strigilia and all the 

 genera of the Styracinecs, It resembles Pamphilia greatly in 

 habit, and appears to difier from it and Strigilia only in the cha- 

 racters above mentioned. If, therefore, its ovules be sometimes 

 more than one in each division, as Prof. DeCandolle suspects, 

 there would not then remain a single feature to distinguish the 

 genus from Strigilia. 



From the materials above cited I have drawn up its generic 

 character as follows : — 



FovEOLARiA, R. & P. Tremanthus, Pers. — Flores subpolygami. 

 Calyx campanulatus, crasso-coriaceus, extus densiter tomen- 

 tosus, margine 5-denticulatus. Petala 5, oblonga, crassa, 

 calyce 2-plo longiora, extus tomentosa, imo (adhsesione sta- 

 minum) breviter connata, sestivatione valvata, apice inflexa.

 sesquilonga, dorso pubescentia, imo sese et cum petalis laxe 

 in tubum connata; anthercB lineari-oblongse, dorso ad fila- 

 menta adnatse, 2-lobse, lobis linearibus, parallelis, distinctis, 

 rima longitudinali dehiscentibus. Ovarium ovoideum, se- 

 riceum, superne 1-loculare, imo brevissime pseudo-3-locella- 

 tum, septis cum nervis totidem parietalibus continuis ; ovula 

 in quoque locello 1 (vel interdum 2) e basi erecta. Stylus 

 cum ovario continuus, gradatim attenuatus, pilosulus, longi- 

 tudine staminum. Stigma breviter 3-lobum. Bacca ovoidea, 

 calyce sufi'ulta, 1-locularis. Semina 1 vel 2, imo ovulis steri- 

 libus notata, structura Strigilia,
