2. Xanthosia tasmanica Domin, Repert. Spec. Nov. Regni Veg. 4: 298 (1907) non Gand., 
Bull. Soc. Bot. France 65: 32 (1918). 
Type. Circular Head, Tasmania, R. Gunn 1837 / 879 (lecto, here chosen, K!, the largest 
specimen in the top left corner). Domin cited two specimens in the protologue for 
X. tasmanica ; ^'prope George Town (Ig. Gunn 1842 sub no. 1122) et Circular Head 
(Ig. Gunn 183/ sub no. 879) (H. Kewense)'. This material, comprising nine elements, is 
mounted on a single sheet at K. Thus there is some ambiguity as to which collection(s) 
were from George Town and which were from Circular Head. The largest element, in 
the top left corner, has a determinavit label below it by Dr Hansjoerg Eichler (dated 
1961) indicating his intention to lectotypify this plant (which he never published). 
The nearest locality label to this plant is for the Circular Head collection. This largest 
p ant is designated as lectotype (in accordance with Dr Eichler's intentions) as it is the 
best specimen on the sheet. 
Erect or ascending perennial herb to 20 cm high. Plants covered by sparse, long, 
spreading hairs. Leaves cauline, trifoliolate. Petiole sheathing shortly at the base, 
sheaths 1-8 mm long. Petiole to 30 mm long, angular, grooved above or flattened. 
Leaflets elliptic, the segments equal or the lateral leaflets split or parted almost to the 
base, 4-15 mm long, 3-8 mm wide, shortly petiolulate; margins entire; apex acute. 
iif orescence a compound umbel with 1-4 rays, sometimes contracted and appearing

bisexual Rays terete, 1-3 mm long. Involucral bracts 1-4, linear, foliaceous, green, 
onger than the rays, 3-4 mm long, 1 mm wide; apex acute. Bracteoles two or three, 
mear, foliaceous, green, shorter than flowers, 3-1 mm long, 1 mm wide; apex acute. 
Inflorescences sessile or pedunculate; peduncles to 5 mm long. Flowers pedicellate.
