196 FLORA VITIENSIS. 
South Wales (Cunningham! F. Mueller! Macarthur! Harvey! Bidwill!), Norfolk Island (Cun- 
ningham !), Oahu, Sandwich Islands (Seemann! n. 2295, Beechey !) ; and Northern Island of New 
Zealand (Siuclair ! Colenso! Bauer!). No locality is quoted for Meyen’s specimens ; they were 
probably picked up in the Philippine Islands. 
Choisy says that this species is easily distinguished from P. Brunoniana, Endl,, by the leaves always 
being acute, not rounded at the base, which is certainly correct; but a much better distinction is, that in 
P. Brunoniana the fruit is covered with spines, and all the leaves are opposite, whilst in P. umbellifera the 
fruit is without spines, and the upper leaves of the branches are generally in whorls. The specimens from Viti 
distributed by me under n. 364, and provisionally named 2. viscida, on account of the viscid nature of their 
utriculus, must be referred here. What has been figured and described in Meyen’s plants (Noy. Act. Nat. 
Cur. vol. xix,, Suppl. p. 403. t. 51), under the name of P. Horsteriana, exactly represents the state of my 
specimens. Choisy erroneously referred P. Horsteriana to P. inermis. P. excelsa, Blume, from Java, is 
alsoa synonym. ‘The same applies to P., macrocarpa, Presl, already referred to P. excelsa by Choisy, and 
P. Mooreana, ¥. Mueller, Nor does P. Sinclairi, Hook. f., from New Zealand, Norfolk Island, and New 
South Wales, of which a branch with hermaphrodite flowers is figured in the ‘ Flora of New Zealan ,; prove 
different; but in his ‘Handbook of the New Zealand Flora” Dr. Hooker confounds it with P. enermis,
