C. SKOTTSBERG 



buted from Australia to Malays., Melan. and Polyn. with a secondary centre in 

 Hawaii (i8); entirely absent from Amer. 



Hookeri {G. Don) W. R. B. Oliver {rg2). Forms a separate monotypical section. 



pyrifolia (Hook, et Arn.) Skottsb. Belongs to a section of 8 Polyn. sp. (4 

 Tahiti, i Cook Is., i Rapa, i Pitcairn, i J. Fern.). 



Galium L. World-wide, essentially boreal. 0\er 500 have been described, almost 

 ^/^ of these Medit.-Orient.; about 50 in S. Amer., mostly along the Andes and 

 extending south to Fueg., F'alkl. and S. Georgia. 



masafueranum Skottsb. Related to G. eriocarpuin Bartl., DC. and iricJiocar- 

 pum DC. (both Coquimbo-Cord. Linares), the fruit as in masafueranuin covered 

 with straight hookless hairs. 



Campanulaceae. 



Waldenbergia Schrad. P^ssentialh' S. African; about 230 sp. (9 S. Amer., 10 S. 

 pAir. -Orient., 2 or 3 St. Helena, 20 trop. Afr., 6 Madag.-^^Iascar., 150 S. Afr., 9 As., 

 I X. Guin., 8 Austral., 8 X. Zeal., 5 J. Fern.i. 



Larrainii (Bert, ex Colla) Skottsb., fernandeziana A. DC. p. p. and Grahamae 

 Hemsl. are closely related to each other. 



Masafuerae (Phil.) Skottsb. approaches the former, but has the large tuber 

 of the following. 



Berteroi Hook, et Arn. occupies a rather independent position. 



Most African species are annuals and quite unlike the island species, and 

 these have little in common with the single Chilean or the other American forms, 

 nor with those from Australia or X. Zealand, even if there is a superficial likeness 

 between W. Masafuerae and a couple of perennial S. African species such as 

 \V. Eckloiiii Buek and oxyphylla A. DC. On the other hand, the resemblance 

 between the J. Fernandez and St. Helena species is quite striking, and in spite of 

 the difference in the number of carpels, the ovary being trimerous in the former 

 and dimerous in the latter, the possibility of a common origin cannot be dismissed. 

 The number of carpels in the genus varies between 2 and 5 ; in most species 

 they are 3. Hemsley {12'j. 61) regarded the St. Helena species as allied to African 

 and Juan Fernandez species. 



Lobelia L. 350-370; particular!)' numerous in Amer. and Afr., less so in As., 

 Austral, and Oceania, 2 in Eur. 



alata Labill. S. Chile, S. Afr., Austral. A sea-side sp. 



Compositae. 



Lage7tophora Forst. A bicentric austr.-subantarct. genus of 16 sp., most numerous 

 in Austral.-N. Zeal.; F"iji, Rapa, extending north to Philipp. Is. and Hawaii. 



Harioti Franch. Andes of S. Chile to Fueg. 

 Erigeron L. A large bor.-temp. genus. Ind. Kew. lists about 700 sp. as valid, 

 half of them in X. Amer. and about 100 in S. Amer., where the genus is richly 

 developed along the Andes, south to Patag., Fueg. and F"alkl. Xot few are known 

 from trop. mountains in the W. and E. hemis[)heres; very few reported from
