Figure 1

(a) Billowed tip of the tendril. (b), (c) Tendril tip with an enlarged swell, the lid is evident, the terminal spur is formed next to the lid. (d) Pitcher gets its typical shape, the spur is fully developed. (e) Pitcher is inflating, the digestive fluid is present. (f) Pitcher begins to elongate, wings start to grow, the spur decreases in size, the peristome is forming. (g) Lower half of the pitcher gets its bulbous shape, the lid has just opened, the peristome is directed vertically. (h) Mature pitcher, the lid has a long neck region, the peristome is bulged. (i) Longitudinally dissected mature pitcher of N. alata (lateral aspect, view from inside) with different functional zones: the lid (LD), the peristome (PS), the slippery zone (SZ), the transitional zone (TZ) and the digestive zone (DZ). Scale bars: 1 cm.
