Keys between confusing species at Lucid Central are as below:

Dutchman’s pipe (Aristolochia elegans) is similar to several closely related introduced species that have also become naturalised in Australia, including pelican flower (Aristolochia grandiflora), fragrant Dutchman’s pipe (Arsitolochia odoratissima) and gaping Dutchman’s pipe (Aristolochia ringens). It is also very similar to the cultivated giant dutchman’s pipe (Aristolochia gigantea) which is often confused with pelican flower (Aristolochia grandiflora) in the horticultural industry. These species can be distinguished by the following differences:
  • Dutchman’s pipe (Aristolochia elegans) has a small ear-like structure (i.e. auriculate pseudo-stipule) at the base of each leaf stalk. Its flowers are relatively large and broad (up to 7.5 cm long and 10 cm wide) and its relatively large fruit (4-6 cm long and about 2.5 cm wide) are oblong in shape with a short projection (about 10 mm long) at the tip.
  • giant dutchman’s pipe (Aristolochia gigantea ) does not have a small ear-like structure (i.e. auriculate pseudo-stipule) at the base of each leaf stalk. Its flowers are very large and broad (up to 30 cm long and 20 cm wide) and its relatively large fruit (up to 8 cm long and 3 cm wide) are oblong in shape with a very short projection at the tip.
  • pelican flower (Aristolochia grandiflora) does not have a small ear-like structure (i.e. auriculate pseudo-stipule) at the base of each leaf stalk. Its flowers are very large (up to 25 cm long) with a very elongated projection at the base of the flower (i.e. appendix) 20-50 cm long. Its very large fruit are oblong in shape (about 10 cm long and 4-6 cm wide).
  • fragrant Dutchman’s pipe (Arsitolochia odoratissima) has a small ear-like structure (i.e. auriculate pseudo-stipule) at the base of each leaf stalk. Its flowers are relatively large and broad (6-12 cm wide) and its moderately large fruit (4.5-8 cm long and 1-1.5 cm wide) are oblong in shape and slightly curved.
  • gaping Dutchman’s pipe (Aristolochia ringens) has a small ear-like structure (i.e. auriculate pseudo-stipule) at the base of each leaf stalk. Its flowers are relatively large and narrow (10-25 cm long) and are split into an upper and lower lobe.

Pl. go through ‎Aristolochia (‎‎‎‎Aristolochiaceae) page with images of species (done by me & …) in efloraofindia.

If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice.
Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
