The foldscope aided microscopical studies were carried over in Passiflora foetida. In the present study, we have taken stem anatomy, trichome and pollen morphology using saffranin stain.
- Passiflora foetida belongs to Passifloraceae family
- P. foetida is able to trap insects on its bracts so it is called as Protocarnivorous plant
- The stems are thin and wiry, covered with minute sticky yellow hairs and leaves are three- to five-lobed and viscid-hairy.
- The flowers are white to pale cream coloured
Attractive blooming flower
T.S OF STEM
Closer view of vascular bundle in Passiflora foetida L. Stem
- It contains single, bidirectional vascular cambium
- In transverse view, vessels are round to oval with different diameter , including very narrow fibriform vessels intermixed.
This pic shows simple unicellular hair in Passiflora foetida L
- P. foetida has both simple unicellular and glandular trichomes.
Admirable foldscope view of pollen grains in the pollen tube
- Exine is thicker and the endine is very thin with very small globular elements
