TRIBE II. CARYOPHYLLACEA. 403 



7. ANTHOPHYLLUM CLAVUS. (Dana.) 



A. daviforme et subdivisum, erectum, 1J' altum. Corallum caliculis 

 cylindricis, parvis, 2-3'" longis et l"' latis, et massd spumosd sur- 

 rectis ; lamellis paulum exsertis, truncatis. 



Claviform and subdivided above, erect, a foot and a half or more high. 

 Corallum with small cylindrical calicles, 2 to 3 lines long, and 1 

 broad, rising from a spongy base; lamellaB a little exsert, truncate.

This species is peculiar in its erect cylindrical or clavate forms, two 

 to four inches in diameter, and in its small calicles. The tubes of the 

 interior of the corallum, are flexuous and crowded, and may be easily 

 separated from the spongy base which unites them. Large areas are 

 covered by these coral stumps. 



APPENDIX. The Anthophyllum spherula of Ehrenberg, was de- 

 scribed from a worn specimen in the Museum Nat. Cur. at Berlin, as 

 follows: "Globosum, pollicare, tubulis 1" nunquam latioribus, totis cel- 

 luloso-concatenatis, ubi partim liberi cernuntur, substriatis, caliculis 

 rotundis, margine paululum prominulis, radiis 12-24, interstitiis inter- 

 dum profundius impressis, irregularibus." Op. cit. Gen. Ivi., sp. 3. 



The Madrepora divergens and chakidicum of Forskal (op. cit. p. 

 136), are probably of this genus, as suggested by Blainville, and the 

 chalcidicum may be identical with the fasciculatum. 



GENUS XI. STYL1NA.- LAMARCK. 



Caryophyllidce fasciculato-glomeratce. Corolla tubulis cylindrids stri- 

 atis, per dissepimenta transversa et scepe massam celluksam connexis 

 stellarum centra exsurgenti.
