volumes of the Orchid Review, the writer feels in a measure responsible for 
the introduction and use of Osmunda -fibre abroad, hence the present 
suggestion for your consideration. E..O. ORPRT, 
(This opens a rather larger question. Is the fibre of Osmunda regalis 
to be excluded as unworthy of the new name? And we have Polypodium 
fibre. If abbreviation is desirable it might be carried further, for the phrase 
“* potted in osmunda,” or ‘‘ polypodium,”’ would be understood.—Ep. ] 
ODONTOGLOSSUM BRAYANUM: A STUDY IN DOMINANCE, 
A VERY interesting Odontoglossum was exhibited at the R.H.S. meeting 
held on March 5th last, by Messrs. W. B. Hartland & Sons, Cork, under 
the name of Odontoglossum Brayanum, with the record of parentage, O. 
Groganie X Harryanum. The flower was nearly as large as in O. Harry- 
anum, and much like it in general shape, the sepals and petals being 
reddish purple, tipped with light yellow, and the lip pandurate, white in 
front, and maroon purple behind, with a yellow spiny crest. So slight was 
the evidence of O. Groganiz (Uroskinneri X Edwardii) that we asked Mr. 
Treseder the history of the cross. He replied that O. Groganiz was the 
seed bearer, and O. Harryanum the pollen parent, and that there was not 
the slightest possibility of error, for they had only a single capsule on 
‘O. Groganiz, from which many seedlings were obtained, though a number 
of them were eaten, and ultimately only three survived. We have thus a 
case of paternal dominance, but we should not be at all surprised to find 
the other two seedlings considerably different when they flower. O. Gro- 
ganiz was obtained from O. Uroskinneri ? and O. Edwardii ¢, the two 
belonging to very distinct sections, and it is interesting to note that in this 
case the hybrid took nearly the shape of the seed parent and the colour of 
the pollen parent, the shape of the one and the colour of the other being 
-dominant, though both were slightly modified in detail. 
O. Groganiz was raised in the collection of J. H. Grogan, Esq., 
Slaney Park, Wicklow, and its history, as given by the raiser, is very 
interesting. He remarks :—‘‘In the spring of 1904 I had a fine spike 
-of 36 buds on a very fine variety of O. Uroskinneri. I fertilised every 
-one of these flowers as it came out with the best pollen I could obtain at the 
time, and not one of them would take. When I came to the last flower the 
only pollen I had available was from a good variety of O. Edwardii, and 
this I used, not in the least expecting to get a pod, as I have found that 
Edwardii pollen is practically useless. To my astonishment a fine seed-pod 
-developed, and in due time the seed ripened, germinated, and the little 
plants throve apace, with the present result. The plant exhibited had an 
inflorescence of 58 flowers and buds, and this on the first bulb from the 
seed bulb. I believe Uroskinneri hybrids have a bad name, but these are
