It'd be better if the characteristic morphological traits of Rosaceae, e.g. the possession of a hypanthium, were described. S.R. Hinsley, http://www.malvaceae.info

Yeah, no kidding! Unfortunately I don't know enough about it to do so, but I was rather disappointed that there weren't really any "distinguishing characteristics" given of such a major family! - 4.252.5.36 05:16, 20 May 2007 (UTC)

[edit] Lyonothamnus

Any idea where Lyonothamnus belongs? To its own tribe? Tom Radulovich 03:34, 31 Mar 2005 (UTC)

Takhtajan's 1997 classification, which was the last major pre-molecular classification of plants, placed it in its own tribe and subfamily (he broke Rosaceae into 12(?) subfamilies, one of which has since been moved to Fabales). The cladogram at http://www.botany.utoronto.ca/faculty/dickinson/rosaceaeevolution/combinedtree.html places it as sister to the clade Maloideae+Prunoideae+Neillieae. I can't find any data to place it confidently in any particular grouping. It might be possible to do a metaanalysis on the sequences deposited in GenBank, but that would take quite a bit of effort, and the result is not necessarily superior to Dickinson's cladogram.

[edit] New Phylogeny Paper

There a new paper out on the phylogeny of Rosaceae - Phylogeny and classification of Rosaceae. Unfortunately it's behind a paywall, so I don't know what it says, but the abstract indicates that Dryadeae is promoted to subfamilial rank, and Maloideae and Amygdaloideae are sunk in Spiraeoideae.
