78 MR. J. MIERS ON THE CERVAtfTESIEiE. 



CEBVANTESIEiE. 



This tribe, first proposed by Baillon in 1862 ! , included Cer- 

 vantesia and Iodina, which he regarded as belonging to the 

 Olacacece. According to him they differ from Santalacece princi- 

 pally by their free ovary 2 , and are closely allied to Vijrularia. 

 He thought that they were also allied to Cansjera, though differing 

 in the number and mode of insertion of the ovules. My own ob- 

 servations show that they belong to Styracece. 



Cervantesiece, tribus St yracearum. Flores breviter calyculati. Calyx ma- 

 jnsculus, calyculo insidens, liber, 5-partitus. Corolla ealyce minor, 

 tubo brevi imo ad ovarium adnato ; segmenta 5, subexpansa, lobis ca- 

 lyeinis alterna. Stamina his opposita et segmentis alterna. Ovarium 

 et semen Styracis structura. Genera Cervantesia et lodina. 



Ceryaktesia. 



This genus of the % Flora Peruviana ' was established in 170-1 by 

 Ruiz and Pavon, with some errors in its diagnosis, which they 

 corrected eight years afterwards on their return to Madrid. In 

 regard to its position in the System, Lamarck first placed it in 

 Santalacece (1811) ; Kuuth accorded with this (1825), and End- 

 licher (1810), likewise Lindley (1858). DeCandolle (1S56) re- 

 garded it as a doubtful genus of that family, I pointed out pre- 

 viously (1851) the very close affinity existing between it and 

 lodina, so close, indeed, that the structure of the flower in the one 

 offered scarcely any discernible difference from that in the other; 

 but as Cavanilles had regarded the calyx in Cervantesia as par- 

 tially agglutinated to the ovary, a circumstance that would place 

 the genus in Santalacece, I did not then venture to remove it 

 from that family. 



Cekvantesia, R. $ P., char, reformato. 



Calyculus parvus, cupulatus, fere ad basin in laeinias 5 acutas fissus ; calyx 

 hoc multo longior, liber, imo hemisphrcricus, 5-angulntus, tubulosus, 

 tubo profunde 5-fido, lobis oblongis, carnosulis, in scstivatione valva- 

 tis, in fruetu auctus et persistens. Corolla colorata, lobis calycinis 

 paullo brevior; tubus brevissimus, ad ovarium arete agglutinatns ; 

 segmenta 5, petaloidea, late oblonga, truneato-emarginata, erecto- 

 divergentia, cireumseisse eaduca. Stamina 5, e margine disci orta, 

 segmentis rcquilonga et alterna, lobis calycinis opposita, glabra; filu-
