Compositae. 



47. Vernonia cinerea /.ess. See p. 118, No. 58. 



Rather numerous on the foot of the basaltic rocks and on 

 the older parts of the littoral plain. 



48- Erigeron linifolius Willd- See p. 51- 



A few specimens at the base of the steep wall which 

 secludes the littoral plain from the interior. 



49- B/umea lacera D- C See p. 51. 



Several specimens on and near the base of the basaltic 

 rocks. 



50. Ercchthites hieracifolia Ra r in- See p. 52. 



Some specimens on the base of the basaltic rocks. 



51. Pluchea imlica less. See pp. 50, 108 and 119. 



Here and there on the older parts of the littoral plain. 



52. Wede/ia biflora D. C. See p. 49 under Wollastonia. 



Numerous, especially on the older parts of the beach. 



From a comparison of the list above with that of the plants 

 collected in the same locality by Ernst and his companions in 1906, 

 it appears that the vegetation in the two intervening years had 

 but little changed. In 1908 were not found back Dryopteris unita O.K. 

 (in 1906 a few specimens on the base of the steep wall formed 

 by the rupture) and Cerbera manghas L. (in 1906 a few very young 

 seedlings on the younger parts of the beach). Whether the first of 

 these two species was really absent in 1908 or was overlooked in 

 the locally dense vegetation I cannot say; it is quite possible that the 

 few specimens growing there in 1906 were all taken away by the 

 botanists then visiting the island. The young seedlings of Cerbera 

 manghas L. collected in April 1906, were found in a locality unfit 

 for their further growth, a beach consisting of very loose sands 

 (see p. 45); they probably died in the east-monsoon of that year. 

 In the westmonsoon very frequently seeds of all kinds germinate 

 on such beaches but do not find a fit habitat there and perish in 

 the course of the next east-monsoon. 



Found in 1908 but not in 1906 were 8 species, namely Spatho- 

 glottis p/icata Bl. (a few specimens), Eulophia macrorrhiza Bl. 

 (3 specimens), Pouzolzia zey/anica Benn. (a few specimens), Ximenia 

 americana L. (1 young specimen), A/bizzia retusa Bth. (1 young spe- 

 cimen), Erythrina fusca Lour. (1 young specimen), Vitex paniculata
