Distal free lobes of the calyx are lanceolate, 7-9 mm long and 4-5 mm wide and outwardly reflexed at an angle of [+ or -] 60[degrees] with the floral axis
. Shallow depression-like glands are present on the ventral surface of the calyx (Fig.
Mirror-image flowers (enantiostyly) are a sexual polymorphism in which the style is deflected away from the floral axis
either to the left (left-styled flower) or the right (right-styled flower) (Jesson & Barrett, 2002; Gao et al., 2006).
However, the "flowers" still show a mixture of flowerlike and inflorescencelike features: the common stamen-tepal superposition resembles an axillary relationship and can be considered more akin to "inflorescence" than to "flower"; the gynoecium is made up simply of carpels inserted on the floral axis
and is consequently just like that of a conventional flower; the phyllotactic sequence of the "flower" is nevertheless continuous through the initiation of the stamen-tepal associations and the gynoecium.
