Nice photo.. I have a similar one in which the sinense has been replaced with ensifolium. Meglee with 'Miss Taipei' as the cultivar name. I have the latter from SBOE and can be seen at

The growth is rather compact compared to many cymbs and will stay in a 1 gallon pot for several years. These two are indeed very similar.
