Masafuera: Germain oct. 1854 (Herb. Santiago!); Q. de las Vacas, on 

 the walls in the outer section (fr. 10 / 2 17, no. 441 — f. tuberculata); stony beach 

 near Varadero (fr. 22 / 2 17, no. 12 16); Q. de la Loberia, near the shore (fr. " '/a 17, 

 no. 485 — f. alulata). 



H. masafuerana differs from all others in the size and shape of the fruit 

 and in the smooth, shiny stems, leaves etc. I have sown seeds of all the 

 different numbers; of no. 1216 I have numerous, of 441 a few plants in cultiva- 

 tion. The difference between them is slight, and the tubercles on the fruit of 



Fig. 20. Halo?'rhagis masafuerana; a- f from no. 1216: a lower, b upper leaves, nat. size; 



c flower on male and d on female stage, X 6,6; e sepal, X 20; f fruits X 6,6. g— h from no. 



441: g petal, X 20; h fruits, X 6,6; i fruits of no. 485, X 6,6. 



the latter become pronounced only with desiccation, but are quite wanting even 

 in the dry fruits of no. 12 16. More material is needed to decide whether 

 no. 441 represents a distinct variety. Of no. 485, the seeds did not germinate. 

 Fruits of all the forms are figured. 



Area of distribution: Endemic in Masafuera.
