Excerpt from The Philippine Journal of Science, Vol. 10: 1915The history of the genus Lithophytum Forskål, formerly Ammothea Savigny, has been well treated by Kükenthal (1903) in his revision of the Nephthyidæ, and by Shann (1912). In his revision Kükenthal included in the genus several species which in his latest work (1913) he has transferred to the genera Lemnalia and Paralemnalia. He there defines the genus Lithophytum as follows:Die weichen und biegsamen Kolonien sind strauchartig oder baumartig aufgebaut. Stets findet eine Verzweigung der Hauptstamme statt. Die Polypen stehen stets in "Katzchen" oder "Lappchen." Ein Stützbündel fehlt, die Polypen sind nicht retraktil. Die dünnen Kanalwande enthalten sparlich spindelformige Spicula, die auch fehlen konnen. Die Polypenspicula, die ebenfalls fehlen konnen, sind bedornte Spindeln, deren Dornen aber nicht zu Kranzen zusammentreten. Verbreitung: Indopazifischer Ozean, in flachem Wasser, auf Korallenriffen.He recognizes 12 species belonging to the genus as thus diagnosed. One of these, Lithophytum acutifolium, is a new species from the Red Sea related to L. stuhlmanni (May). Two other species have been proposed by Thomson and Henderson (1906 and 1909).About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
