William T. Baxter (1788-1871) was a British garden and landscape
designer and Curator of the Oxford Botanic Gardens from 1813
to 1848. He is credited with introducing the waterlily N. 'Daubenyana',
thought by some to be a tropical day-blooming viviparous hybrid
between N. caerulea and N. micrantha, named for Dr. Charles Daubeny.
Taxonomists currently cite N. 'Daubenyana's' original publication
in 1864 (Suppl. Oxf. bot. gard. 40. 1864) but it may have existed
much earlier. A reference from 1912 says that the hybrid originated
in the Garden about 1851 and was mentioned by Maxwell
Masters in Gardeners' Chronicle, May 24,1856. The name 'Daubenyana'
is not stated in the Masters article but we presume it is the
waterlily referenced. There it is given as "what he (Baxter)
thinks a variety of that plant (N. micrantha) or possibly a hybrid".
