Of this two .sets of specimens were collected, no. 442 with smooth fruits 

 or occasionally with a trace of wings, and no. 457 with 4-winged fruits; single 

 cases were, however, almost devoid of wings. Seeds of both numbers were sown 

 Jan. 3, 1921, and 10 plants of each potted separately May 11. Of no. 442 

 about 2 000 ripe fruits were gathered Jan. 22, 1922; all were quite smooth except 

 a dozen, where from one to four small wings had developed. No. 457 gave 307 

 fruits; most had a trace of wings, but only 16 were t}'pically 4-winged. 



84. Halorrhagis masatierrana Skottsb. 3. 15;. 



The fruit seems to vary a good deal in size in difterent individuals; see 

 also Skottsb. 5. 155. Unfortunately, I did not manage to raise this species 

 from seed. 



85 Halorrhagis masafuerana Skottsb. 3. 156. 



Of this I had three sets of specimens, nos. 1416 with very smooth, quite 

 wingless fruits, no. 441, equally wingless, but faintly rugose-tuberculate, and 485, 

 where here and there a wing had been developed. Of all three fruits were sown, 

 but no. 485 did not germinate. Nos. 441 and 12 16 were sown the same day 

 as H. asperrima, and of the former 5, of the latter 8 vigorous plants were 

 potted separately June 13. Ripe fruits were collected Jan. 23, 1922. Of both 

 numbers there were single fruits faintly tuberculate-rugose transversally. In habit, 

 leaf shape, colour, pubescence, etc. both species have proved constant.

Masatierra: Bock! 



We have no good reason to suspect this to be a late introduction; perhaps 

 it is, but just as well it may have been overlooked. 



Area of distribution: Chile, 36° — 44°, Juan Fernandez. 



Authentic material of "Uredo Hydrocotyles Montague" is in Herb. Uppsala 

 (Herb. Elias Fries), two intact leaves of the host plant, resembling H. niodesta 

 Cham, et Schlecht. and labelled "Bertero J. Fernandez herb. Montagne". If the 

 locality is correct, a species of Hydrocotyle occurs or, in any case, once occurred 

 on ^Masatierra.

 3. 160. — On my request one of my students made a comparative anatomical 

 study of E. fernandezianum and its supposed parents (alcohol material of all 

 available). The results, which have not been published, confirm my view that it 

 is of hvbrid oricrin.
