Pentas lanceolata?

I see an image of a plant with four petalled pinkish flowers labled Pentas lanceolata in the article. But this page says Pentas lanceolata is five petalled and 'Pentas' in the name justifies just that. Most probably this is Ixora coccinea. I am not an expert at this, so somebody please confirm and make the correction. The image name might also needs to be changed in the commons. ~ srini 15:10, 24 October 2006 (UTC)

Really it is an Ixora species. Genus Ixora has flowers with four corolla lobes, rarely five.Besides Pentas has the valvate aestivation while Ixora has the convolute aestivation like on picture.Berton 15:23, 24 October 2006 (UTC)

The two users above are clearly correct about the misidentification of the photograph. I believe that it is high time to make corrections. 72.130.245.132 (talk) 04:54, 8 June 2009 (UTC)

The photo in question is File:Egyptian starcluster-KayEss-1.jpeg. I've gone ahead and removed it from this page. If someone wants it back, I wouldn't object to that (with correct identification), but ideally the images would illustrate specific points rather than being a grab-bag which are just sitting in a gallery (see MOS:IMAGES).

Mistake?

It's my impression that the article says that the genus Astragalus is in the Rubiaceae family, but instead it is in Fabaceae the pea and bean family. Can someone take a look at this?

The two bigger genera are prefised by the vernacular names of the family they belong to, hence 'legume' and 'orchid'. It seemed obvious to me that their non-membership of rubiaceae was implied (?) If not I guess we can reword. Casliber (talk · contribs) 01:11, 4 February 2010 (UTC)

Omit exact species count

I reverted the edits that changed "more than 13,000 species" to "more than 13,443 species" along with the reference, which does not directly state any number of species. Even if it is possible use that reference to generate a species list and count them manually, there is no reason to believe that the count is complete and contains no duplicates and no subspecies, varieties, forms, and cultivars, especially ones that this database may call species but other authorities may consider duplicate names or subspecies, varieties, forms or cultivars. Also, the definition of species is fuzzy, especially among plants, which can often hybridize within and across genera, so when the species count is over 13,000, exact species numbers are likely to be a matter of opinion, and Wikipedia should use words like "more than" with a round number, rather than an exact number, unless there is strong reason to believe that a species count is complete and contains no duplicates and no entities of taxonomic rank lower than species. Also, there was an improper space before <ref>. Anomalocaris (talk) 05:29, 5 April 2010 (UTC)

Actually ref #2 does give an exact number. But I agree that 'more than' is correct for the lead. Guettarda (talk) 06:05, 5 April 2010 (UTC)
