From the pattern:

A delicate bouquet pattern in a Japanese stitch dictionary begged to be knit into a pair of mittens. The motif is framed in a cabled pattern to add a level of interest. If mittens in sock weight yarn seem too fine, or if you are a bit short on yarn, try the fingerless mitt variation instead!

The pattern features both mitten and fingerless mitt instructions.

EDIT: I have uploaded a larger version of the chart key as a separate pdf. The pattern pdf is called “Bouquet-english” and the pdf with ONLY the chart key is called “bouquet-chart-large”.
