As a comment about Mesembryanthemum Mezoo™ Trailing Red, rattlebox wrote:

Although this plant was apparently trademarked as Dorotheanthus bellidiformis 'Mezoo Trailing Red', and therefore widely and generally identified as a variety of Dorotheanthus bellidiformis [Livingstone Daisy], it clearly is not. It is much more closely allied to Aptenia cordifolia 'Variegata' (now Mesembryanthemum cordifolium 'Variegata').

The leaves of Dorotheanthus bellidiformis are elongated, almost spatulate, often twisted and curled, covered with obvious papillae; the stems are round (also covered with obvious papillae), and the flowers are large (1 1/2-2") with a large "daisy eye". The leaves of Mesembryanthemum cordifolium are wide, heart-shaped with a pointed tip and nearly smooth (papillae are much reduced in comparison); the stems are square, and the flowers are dime-sized or slightly larger with tiny, almost obscured eyes.

I have read that 'Mezoo Trailing Red' is simply a variegated version of Aptenia 'Red Apple' (a hybrid of Aptenia cordifolia and A. haeckeliana). Whether this is strictly true or not, it is certainly closer to the true identity of 'Mezoo Trailing Red' than being called Dorotheanthus bellidiformis.

(Note: Aptenia spp. are now classified as Mesembryanthemum spp.).

The Aptenia entries currently listed as accepted names in our database will be merged with the appropriate Mesembryanthemum entries tonight. I agree that Mezoo Trailing Red obviously is another Mesembryanthemum, and I'll take care of that entry as well.

Thanks for your response!

I was not really expecting any changes to the database as a result of my post, I simply wanted anyone that viewed this plant to have a better understanding of it's identity.

Updating the database not only accomplishes that, but will help sort out confusion as to the identities of the common name "Livingstone Daisy" and of the scientific name Dorotheanthus bellidiformis.

It's nice to know my input can add real value to this database. It's nice to feel appreciated!
