The inflorescence is terminal and/or axillary with three to five tepals
Flowers 5,2-5,8 (-6,1) cm long, green-yellow to light green; ovary 2,3-3,0 (-3,2) x (0,4-) 0,5-0,8 cm; tube (0,5-) 0,8-1,6 x (0,5-) 0,7-1,0 (-1,2) cm; tepals
equal, triangular, united at base, 2,5-3,0 cm long; stamens inserted 0,30-0,32 cm above tube, filaments 4,5-5,5 x 0,08-0,12 cm, anthers versatile, yellow, 1,4-1,5 (-1,6) x 0,08-0,10 cm.
The six tepals
(a combination of petals and sepals) are bright yellow, as are the six stamens.
The flowers are yellow to green--yellow, actinodromous, with six subequal tepals
, nine bilocular anthers and unicarpelar, unilocular, minutely pubescent ovary, sunk into the floral tube in a hypanthium that develops with fruit ripening forming a turbinated cupule, often 4-to 5-parted, red-colored, with floral remains in the margin.
The flowers are pedicellate and monochlamydeous with six yellow-greenish tepals
, an androphore and numerous stamens (see Figure 1D).
The section Nais was described basis on the urceolate shape of the perigone and arcuate-recurved inner tepals
of Cypella aquatilis Ravenna, the type of the section, C.
Intrafloral visitors were those that landed inside the tepals
and on sexual organs of the flower.
4-4 mm wide; tepals
drying yellow-brown, minutely papillate, often turned up markedly on drying; lateral tepals
The flowers are composed of 6 blue lilac tepals
, persistent tepals
fused along half their length into a perianth tube; the androecium consist of six stamens inserts at different levels, with long-, mid- and short-styled morphs (hereafter referred to as the L, M and S morphs, respectively), and a yellow mark or nectar guide on the upper middle lobe.
A Himalayan native, it often has flowers measuring 20cm across with around 15 tepals
, ranging in colour from white, pink through to crimson.
The nodding heads are scented with recurved and twisted tepals
which range from blue-mauve to deep purple with white to yellow stamens.
Fleshy perianth formed of four fused tepals
, becoming spongy in fruit.
