Scientific Committee, March 23, 1920. 
Mr. E. A. Bowles, M.A., in the Chair, and eleven members present. 
Leersia oryzoides. — Mr. J. Eraser showed specimens of this very rare plant 
from its British localities. 
Propagation from Orchid flowering- spike. — Mr. J. Wilson showed pieces of 
flowering spikes of Phalaenopsis, Cattleya, &c., showing propagation from 
these. Sir Everard im Thum remarked that the formation of vegetative shoots 
from flowering spikes of orchids growing in a wild state was frequent. 
Proliferous Primrose. — Mr. Chittenden showed specimens of primrose having 
at the apex of the scape a flower with perianth pieces of the form of bracts, from 
the axils of which flowers had developed. 
Various Flowers. — Mr. H. J. Elwes sent a list of many plants now in flower 
in his garden: Anemone ranunculoides, A. fulgens, A. blanda var. scythinica, 
next to Chionodoxa, the most lovely weed and the most harmless in the garden ; 
very varied forms from Algeria of A. coronaria; Adonis vernalis ; Corydalis 
thalictrifolia, also a weed but a very pretty one ; C.Allionii; Cardamine trifolia;

Mr. E. A. Bowles, M.A., in the Chair, and twelve members present. 
Certificate of Appreciation. — A Certificate* of Appreciation was unanimously 
recommended to Mrs. Backhouse for her work with Daffodils. 
Various plants. — Mr. H. J. Elwes showed plants as follows : — Plants in a 
Cotswold garden 530 feet above sea level. During forty-eight years I can 
never remember a spring so early and so free from east wind and frost as the 
last month has been. The number of flowers out and coming out is quite 
unusual, and as I may never see the like in April again I will mention a few 
of the most beautiful and less common. The three flowering shrubs, though 
not at their best most beautiful, are Berberis Darwinii, which was nearly 
killed three years ago ; Viburnum Carlesii, which has not as yet gone through 
a real Cotswold winter; and Prunus nana, perhaps the choicest and neatest 
little bush that ever came here from Bitton. Anemone scythinica is seeding 
itself everywhere, and is one of the most beautiful and least harmful weeds 
in cultivation. Anemone alpina from seed, not yet fully estabhshed, but seems 
to like a rich border ; Corydalis bracteata, another beautiful weed which comes 
up everywhere but not very easy to pull up ; Daphne Mezereum and var, album, 
which comes true from seed, and comes up in many places but is not long-lived 
here ; Daphne Blagayana, nearly over (keep on earthing up the young growths) ; 
Euphorbia polychroma, Myrsinites, and pilulifera, all pretty, early, and hardy 
border or rock plants ; A rmeria caespitosa ; Sedum Palmeri and Sedum Treleasii, 
both very pretty and doubtfully hardy ; Geum Rossi, a New Zealander, pretty 
but not very floriferous ; Androsace sarmentosa, the earliest of its section and 
one of the best ; Paeonia Mlokosewitschi, the best and earliest yellow paeony ; 
Paeonia Cambessedesii, the best and earliest purple paeony ; Paeonia cretensis, 
the best and earliest white paeony. None of these are fully out, but the buds 
show colour ; a frost would ruin them now, but they are so good and rare that 
they are worth protection. Ourisia macrophylla, close under a north wall, shows 
precocious buds ; it is doubtfully hardy here. Smilacina paniculata, a wonderfully 
strong plant already in bud and four feet high. This was raised from seed that 
I gathered at Niagara Falls. Arnebia echioides, a month before its usual time. 
Dentaria pinnata, a very beautiful plant ; but the white variety is even better. 
Can anyone send me the latter, which is common in Cornish gardens ? Stylophorum 
japonicum, a good doer in my garden ; Jeffersonia dubia, a very pretty plant, 
which, however, does not thrive in my soil and does at Kew ; Epimedium sp., 
which I have under the name of sulphureum ', Potentilla alchemilloides, a pretty
