Gentianaceae. 

 Erythraea Borkh. 



*2j. E. australis R. Br. 



» Abundant, rocky plains, La Perouse Bay (i. e. Hanga Ho Orno); Alba- 

 tross Dec. 16 (no. 19!) — Had disappeared long before our visit, but seedlings, 

 apparently belonging to this species, were observed. 



Area of distribution: Australia; Easter I. 



Convolvulaceae. 

 Calystegia R. Br. 



*28. C. sepiuni (L.) R. Br. forma. 



In the crater of Rano Aroi, c. 400, among large boulders. — A rather 

 narrow-leaved form, probably belonging to this species; only sterile specimens. 



Area of distribution: Widely dispersed in temperate regions, also in 

 Australia, Tasmania, New Zealand, etc. 



Ipomaea L. 



29. I. pes caprae (L.) Roth. 



Apparently rare. Near Vaihu (»I. affinis pes caprae», FUENTES 1. a); 

 Hanga Ho Orno, stony beach on the water's edge (no. 634). 



Area of distribution: Widely dispersed on tropical shores. 



Solanaceae. 

 Lycium L. 



*3<d. L. sandvicense A. Gray. -- Plate 8 fig. 2; text fig. 2 d. 



Rocky shore below the western slope of Rano Kao (no. 644). — Rather 

 an interesting discovery. The specimens are exactly like Hawaiian ones in 

 the Kew Herb., and also agree very well with the description in Proc. Amer. 

 Acad. VI (1863) p. 44. The leaves show numerous whitish pustules, irregular 

 vesicles in the mesophyll, filled with salt. 



Area of distribution: Hawaii, Easter I.
