pedicel), while 1 (from P. X Godseffianum) and 2 (from P. barbatum) only 
measure g lines; 6 (from P. Curtisii) and 7 (from P. Charlesworthii) 
measure Io lines; and, lastly, 4 and 5 (both from P. X cenanthum) are 
about aline longer. The seeds of 4 and 5 are marked as ‘“‘very poor,” and 
of r “poor.” There is also a variation in the period of ripening, varying 
from nine months in 4 and 5, to 13 months in 1 and 6, but the significance 
of this is not so apparent as it would have been if all had been pollinated 
on the same date. , 
As to the cause of this variation we can at present only offer one 
suggestion; namely, the possible influence of the pollen parent. That 
such an influence is sometimes exerted—on the seed envelopes (e.g. in the 
orange) and integuments (e.g. Lilium) has been stated, but some have 
regarded the evidence as inconclusive, and it would be interesting if a series 
of experiments were instituted to test the point. Species which possess 
some distinctive peculiarity in the sculpture of the seeds, or in the shape 
and colour of the fruit, would be suitable subjects for such experiments. 
It is interesting to note that, so far as the present genus is concerned, Mr. 
Young is making the experiment of intercrossing certain species, controlling 
the same by self-fertilising both parents, in order to know what the normal 
capsule is like, and that the results will be published hereafter. 
As regards the result to the particular plant of P. concolor, Mr. Young 
adds that it still looks as well as ever, being now carrying a fresh pod (the 
pollen parent P. x Eyermanianum var. Hermione), a bud just about to 
open, and another which will be a little later. 
CATTLEYA PORPHYROGLOSSA. 
SOME time ago a question was asked by Mr. E. A. Orpet, South Lancaster, 
Mass., as to the identity of Cattleya Dijanceana, a supposed natural hybrid 
obtained from Messrs. F. Sander & Co., and which was one parent of some 
seedlings he has raised. The following note of a plant exhibited at a 
meeting of the R.H.S. on September 8th, 1891, seems to afford the 
necessary clue :—‘‘ Messrs. F. Sander & Co., St. Albans, exhibited ‘ 
an extraordinary small form of Cattleya granulosa called C. g. Dijanceana- 
The flowers of this form are much smaller than those of the type; sepals 
and petals green and unspotted, the side lobes of the lip are white, and the 
middle lobe reduced to a narrow, warted, rose-coloured blade; the column 
is yellow tipped with purple” (Gard. Chron., 1801, x., p- 310). This plant 
is evidently C. porphyroglossa, Rchb. f., which was introduced from the 
province of Minas Geraes, by Messrs. Sander, and flowered in their 
establishment in August and September, 1891.
