Nymphaea jacobsii is a species of waterlily endemic to Queensland, Australia. [2]
Nymphaea jacobsii is an annual or perennial aquatic plant with elongate to globose rhizomes. The broadly elliptic, 40 cm long, 35 cm wide, petiolate leaves have a dentate margin. [3]
The inodorous flowers extend up to 30 cm above the water surface. The sepals are 4.2–13 cm long, and 5.5 cm wide. The 12-24 white to deep blue, lanceolate petals are 1–11.5 cm long, and 2.5-5.5 cm wide. The androecium consists of 150-300 yellow stamens. The gynoecium consists of 12-25 carpels. The globose, 2.3–9 cm wide fruit bears numerous large, ovoid, 2.6–7 mm long and 2–3.5 mm wide seeds with 0.1-0.13 mm long trichomes. [3]
It was first described by Carl Barre Hellquist in 2011. [2]
The Type specimen was collected by S. W. L. Jacobs and C. B. Hellquist in Lake Powlanthanga, Queensland, Australia on the 12th of June 2007. [4] [3]
Two subspecies, namely Nymphaea jacobsii subsp. jacobsii, and Nymphaea jacobsii subsp. toomba Hellq., have been described. [2] [3]
It is placed in Nymphaea subgenus Anecphya. [3]
A natural hybrid of Nymphaea jacobsii and Nymphaea violacea has been described, but not named. [3]
It is named after Surrey Wilfrid Laurance Jacobs. [3]
The NCA status of Nymphaea jacobsii is Special Least Concern (SL). [1]
