Inflorescence

The spadix (Fig. 8) contains, as usual for Cryptocoryne, female flowers at the basis with vertical to almost horizontal stigmas. The olfactory bodies are shortly club-shaped and more or less lobed at the top. The male flowers at the top have a strongly mammillose surface. The kettle is constricted on the inside above the middle. The valve that closes the kettle is red spotted, as is the upper part of the inside kettle wall. The inside of the tube is also spotted, often showing a transition between the markings in the kettle and those on the limb of the spathe. The upper part of the inner side of the kettle wall has more or less circular depressions, alveoli, of unknown significance, but also found in other species, e.g. the C. beckettii group from Ceylon.

The limb of the spathe varies in length from 1 to 6 cm, and is more or less spirally twisted, sometimes becoming uncoiled (Figs. 8, 9, 10). The limb of the spathe is whitish to yellowish to greenish to grayish grounded. It is also so that the colour of the limb varies during flowering, being darker and more intense just after opening, and on the second and third day begins to fade. The markings on the limb of the spathe vary in form from small to large spots, from short, thin streaks to long, thick, irregular lines. The density of these markings varies from almost complete covering of the limb to nearly missing. Their colour varies from brown to red purple. A margin on the limb of the same colour as the markings may be present or absent. The shape and colour of the markings are characteristic for each species.
