formed up to the level of the bases of the remaining sepals. If 

 now the rose " hip " is to be regarded as resulting from the con- 

 crescence of the sepals — in other words a calyx-tube — we would 

 expect a hiatus in its side from the base of the oddly placed 

 sepal upwards, which precisely does not occur. It would, how- 

 ever, not be impossible for the tissue from the sides of the hiatus 

 to extend across the space and, by coalescing, obliterate it. We 

 would then expect to find some evidence of disturbances in the 

 direction of growth in the arrangement of the tissues, but this we 

 do not find to be the case. 



Regarding the hip as a receptacle (or torus) — that is, a vase- 

 shaped expansion of the end of the axis — we would expect that 

 under some conditions the sepals might appear at any point 

 on its surface, and that the receptacle would be completely closed 

 at the same time. This is the condition here found. 



The condition above described appears to have the same mor- 

 phological significance as that occasionally seen in the apple, in 

 which a leaf or a very much shortened shoot, looking like a 

 potato "eye," is sometimes found on the side of the fruit. Such 

 a case as the former is mentioned by Bailey in his book, " Les- 

 sons With Plants " (p. 289). An apple with a shortened axis 

 borne on its side was shown at a meeting of the Torrey Club 

 some time ago. Francis E. Lloyd. 



Notes on a Long Island Moss. — In the April number of 

 Torreya on page 50, in his Additions to the recorded flora of 

 Long Island, Dr. Grout listed Raphidostegium admistum (Sulliv.) 

 as if it were a new combination. This had been published by 

 Kindberg in the Bryineae of Europe and North America (1 : 64. 

 1897) as R. admixtum and specimens had been distributed in 

 1900 by Heller in his Plants of Porto Rico, nos. 4350 and 4496 

 as R. admixtum (Sulliv.) Ren. and Cardot. Dr. Grout has sent 

 us specimens from Jamaica (Long Island) which have been com- 

 pared with Wright's Cuban mosses no. 121 — the co-type of Hyp- 

 num admistum Sulliv. The Long Island specimens are not refer- 

 able to this species, but to H. micaus Sw.
