890 CAMPANULACEAE. | Wahlenbergia. 
Of the 8 species admitted in the following account, W. gracilis is usually 
supposed to extend to Australia and New Caledonia; W. vincaefolia is probably more 
plentiful in Australia than in New Zealand; while the remaining 6 are apparently 
confined to New Zealand.

1. W. gracilis ,Schrad. in Blumenbachia in obs. (1827) 38.—A very 
variable annual herb 6-18in. high. Stem slender, angled, branched from 
the base or in small specimens simple, glabrous or sparingly hairy 
near the base. Leaves usually remote above, more closely placed below, 
alternate or occasionally the lower ones subopposite, very variable in size, 
4-14 in. long, #s-}1n. broad, linear-spathulate or linear-obovate to linear- 
lanceolate or linear, sessile, sinuate - dentate; margins thickened and 
cartilaginous ; surfaces glabrous or sparingly hairy. Upper leaves smaller 
and narrower. Peduncles slender, terminating the branchlets, which thus 
form  few- op ate es racemes. fPedicels slender, $-l4in. long, glabrous. 
Flowers small, $-4in. long, dark or pale, blue, pees nearly white. 
Calyx 5-lobed, coat tube narrow-obconic. Corolla variable in size, 
campanulate. Capsule Lt in, long, obconic, narrowed into the pedicel.—

Mr. N. E. Brown states that Forster’s type specimen, now at Kew, cannot be 
exactly matched with any specimen that he has seen from Australia or New Zealand, 
and he therefore gives a description based on Forster’s type. So far as New Zealand 
is concerned, however, I have little doubt that the common Wahlenbergia of the country, 
aaa in almost all districts, is for all practical purposes identical with Forster's 
plan
