19. TOWNSONIA Cheesem. IGG. 
A small slender terrestrial herb. Root of creeping fleshy caudicles 
thickened here and there into small tubers. Radical leaves 1-3 from the 
caudicles, rarely at the base of the flowering-stem, pétiolate, ovate-orbicular. 
Cauline leaf or empty bract solitary half-way up the stem, sessile, ovate, 
acute, often much reduced in size. Flowers | or 2, small; perianth hori- 
zontal or deflexed. Upper sepal much incurved, broad, concave, almost 
galeate ; lateral placed in front of the lip, lanceolate, margins involute. 
Petals minute, erect. Lip clawed on to the base of the column; lamina 
erect, undivided, broadly ovate-rhomboid, subcordate at the base, entire, 
margins involute and clasping the column towards the base; disc smooth, 
without calli or ridges, or with an obscure thickening on each side near 
the base. Column rather shorter than the lip, erect, broadly and equally 
winged from the base; wings not continued upwards behind the anther. 
Stigma prominent, placed just under the small rostellum. Anther terminal, 
erect, 2-celled ; pollinia free, granular. ( eter, TRS NL 775227 
A very curious little plant. It has the habit of Adenochilus, but differs in the 
smooth undivided lip, minute petals, and in the column-wings not being produced 
upwards behind the anther. The smooth undivided lip also separates it from Chilo- 
, glottis, Caladenia, Burnettia, and other allied genera. The genus has been studied in 
detail by Dr. Schlechter, who has published his results in a paper entitled “ Die Gattung 
Townsonia”’ (Fedde, Repertorium, ix (1911) 249). He considers that its nearest ally 
is Acianthus. He is further of opinion that the Tasmanian Acianthus viridis Hook. f. Rude 
is a true Townsonia, and should be transferred to that genus. At the same time he yy Na 
admits that Townsonia differs in the broadly winged column, a character not founde.,, IR, . 
in Acianthus or allied genera. T'ownsonia is dedicated to its discoverer, Mr. W. Town- 19343 
son, late of Westport, but now of Thames, who is well known from his successful . 
botanical ¢ exploration of the north-western portion of the South Island.
