xl PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 
Sports from root-cuttings. — Dr. Bateson showed a Pelargonium raised from 
a root-cutting of the variety ' Ascot,' which has a rolled-back petal with magenta 
spots on a white ground, whereas the plant raised from the root-cutting had a 
flat petal, larger than the parent, with a large purplish spot. Of four root- 
cuttings raised at Merton three had proved different from their parents, 
Cheiranthus x Marshallii. — Mr. Marsden Jones showed a branch from his 
pale-budded hybrid with pale flowers similar in colour to those of C. alpinus, 
but of the size of the hybrid. He also showed some hybrid Tulips. 
Iris Seedlings. — Mr. Dykes showed seedlings of Iris ' Kharput ' having a 
long fall and of /. germanica with inflorescence branching from the base with 
an herbaceous spathe. The habit, evergreen character of foliage, and partially 
herbaceous spathe of /. germanica, have led Mr. Dykfs to conclude that /. 
germanica is not a really wild plant, and the nature of the seedlings suggests 
that /. aphylla is one of the parents, but the other parent is unknown. 
Rhododendrons . — Mr. Magor, of Lamellen, St. Tudy, sent the following rare 
Rhododendrons : R. campy logynum, collected by Forrest on the Tali Range, a 
dwarf undershrub, the seedlings raised by Mr. J. C. Williams ; R. apodectum, also 
of Forrest's collecting, raised by Mr, Magor, from the Shweli-Salween Range, a 
shrub of 4 feet to 6 feet ; R. ledoides from Yunnan, a shrub of 2 feet ; and R. sp. ?, 
related to Azalea indica, from the Chutong Hills. The last two both raised by 
the exhibitor. Mr. M. Yorke sent a plant called R. Edgarianum, which bore 
dark violet-purple flowers and was strongly aromatic. The Secretary was 
desired to send votes of thanks to the exhibitors of these interesting plants. 
Scientific Committee, June i, 1920. 
Mr. E. A. Bowles, M.A., F.L.S., in the Chair, and five members present. 
Wheat-ear Carnation. — Mrs. F. E. Longhurst sent a shoot of Carnation of the 
variety ' Congress,' showing the well-known ' wheat- ear ' formation in a marked 
manner. 
Various plants. — Mr. H. J. Elwes, F.R.S., showed examples from his garden 
of Blandfordia superba. a seedling Eremurus v/ith sessile flowers ; Dianella 
tenuissima, which bears deep indigo-blue berries ; Littonia modesta ; Paeonia 
decora (= P. lobata, but the nomenclature of these species appears to be involved) ; 
P. Broteri from Portugal ; Eria ornata, the leaves of which appear to be normally 
orange, a native of Borneo ; Tricyrtis latifolia, which Mr, Hales stated had grown 
outdoors at Chelsea uninjured for seven years ; Habranthus &p., which failed to 
flov/er until mulched with leaf -mould, after which it grew and flowered well. 
Aquilegia hybrid. — Mr. Marsden Jones showed a hybrid between Aquilegia 
vulgaris and A . canadensis, showing the characters of both, which he had named 
A. X vulcan var. Phyllis. 
Scientific Committee, June 15, 1920. 
Mr. J. W. Odell in the Chair, and three members present. 
Hen and Chickens Marigold. — Mr. Chittenden showed a Marigold {Calendula) 
with subsidiary stalked capitula arising from the base of the main capitulum as in 
the ' Hen and Chickens ' Daisy. 
Hybrid Lilies. — Mr. A. Perry showed several hybrid Lilies raised by him, 
namely, Lilium x Perryi (L. Washingtonianum x L. Roezlii) and the reverse 
cross, L. X Bowlesianum (L, Roezlii x L. Washingtonianum), and L. x Bal- 
fourianum (L, Roezlii x L. pardalinum). A Certificate of Appreciation was 
unanimously recommended to Mr. Perry for his work in raising these hybrids. 
Tilia with four cotyledons. — Mr. J. Eraser showed a seedling of Tilia platy- 
phyllos with four cotyledons. He considered this condition to be due to the 
coherence of two embryos. He found it growing upon Leatherhead Downs. 
Scientific Committee, June 29, 1920. 
Mr. E. A. Bowles, M.A., in the Chair, and eight members present. 
Gall on Yew. — Mr. J. Fraser showed galls on yew due to Cecidomyia taxi. 
Silver-leaf on Sloe. — He also showed a specimen of silver-leaf on sloe, collected 
from a plant wild on Fetcham Downs. 
"' Stool shoots of Popiilus canescens. — Mr. Worsley drew attention to the large 
foliage of stool shoots of Populus canescens, some of the leaves measuring up
