G. latifolius var. Ikariae. Leaves re volute, deep green, 
with large green spots on inner segments, late flowering. 
(See Gard. Chron. 1893, xiii. p. 506.) 
III. * — G. plicatus Bieb. 
' Dragoon/ A seedling of Allen's. 
chapelensis. A major form. (See Allen, R.H.S. Journal, 
1891, p. 175.) 
byzantinus Baker ? A hybrid plicatus X Elwesii, but breeds 
true. Leaves of plicatus, flowers of Elwesii. (See 
Gard. Chron. 1893, xiii. p. 226.) 
IV. ' — G. Elwesii. 
Var. Cassaba has inner segments, almost entirely green. 
(See Gard. Chron. 1899, p. 165.) There is a robust form, 
called by S. Arnott Elwesii Cassaba Boydii. 
Var. robustus — Elwesii. (See Gard. Chron. 1893, hi., 
p. 226.) 
Elwesii hybrids : — 
Colesborne var. ( ? Elwesii x caucasicus.) 
Similar, but with wider leaves and more green in inner 
segments. 
V. - — G. Fosteri Baker. 
(?) A hybrid between Elwesii and latifolius, but more pro- 
bably a true species. (See Gard. Chron. 1889, v. p. 458.) 
Plantago Roots.- — Dr. J. A. Voelcker drew attention to the change 
in colour of roots of Plantago, which become quite red on exposure to 
the air owing to the production of anthocyanin. 
Double Primula sinensis. — Mr. E. J. Allard showed the result 
of crossing a double form of P. sinensis with a single. Two double 
forms are known, one in which several petals are produced within 
one another, the other in which two rows occur, the inner being 
reversed in colouring. Mr. Allard had searched over a number of 
plants of P. sinensis alba plena, in which the flowers are of the former 
type, shown by Messrs. Veitch, and had found one flower with a 
normal stigma, none with pollen. He pollinated this flower with 
pollen from a single magenta-flowered plant, and obtained three 
seeds, which gave two plants bearing normal single flowers tinged 
white. These were self -pollinated, and gave seventy-four plants, 
seventy-two of which were single, two double, both white, and with 
the older form of doubling similar to the double parent of F % . 
Origin of Peloria &c.*— Colonel H. E. Rawson showed a number of 
dried specimens to illustrate the various correlations which accompany 
the growth of supernumerary spurs in Tropaeolum. Although a 
flower with three spurs and no other variation was the first to appear, 
and out of the first ten flowers only two varied in the number and
