observation, and it makes the present case still more parallel to 

 that of the finding of Capsella Reegeri. The new form has evi- 

 dently sprung from the true R. maritima at the spot. I will repeat 

 the wish expressed above as to a thorough study of the plant in situ 

 and only regret that an experimental study of a plant of this kind 

 would involve considerable difficulty. 



In a paper on the postglacial plant-remnants of the moors of 

 Norway, Jens Holmboe*has mentioned (p. 149) and figured {pi. 2, 

 f. ig) an anomalous fruit of R. maritima in which the two fruitlets 

 were united at their base and supported by one very long common 

 podogynium, thus a case much resembling the fruits of the new 

 Porto Rican species. He says that he found only one fruit of that 

 kind amongst several thousand normal fruits. I owe this reference 

 to Mr. Knud Jessen of Copenhagen.
