CCXViii PKOCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



of the chlorophyH was apparently due to the stimulus produced by the local 

 irritation set up by the presence of the galls. 



Plants from Botanical Gardens, Cambridge. — Mr. E. Irsvin Lynch 

 sent the following for exhibition : — Gerbera, a new variety named " Sir 

 Michael." The disc florets are peculiar in having two thread-like petals 

 on one side, and three longer ones on the other. It may be noticed that 

 this condition sometimes occurs in the transitional state of disc florets in 

 semi-double Daisies, &c. Mr. Lynch writes : " The magnificent Gerbera 

 Jamesoni, sometimes called the 'Barberton Daisy,' is now so well known 

 to all lovers of good plants that a perfect idea of this new and valuable 

 addition to our gardens may be conveyed by the information that it 

 is practically the same, except for its beautiful lemon-yellow colour — a 

 difference of great importance from a garden point of view. There are 

 one or two other slight differences ; first, in the total absence of purple 

 tint about the leaf-stalks, and possibly in a greater obtuseness of the leaf- 

 segments. The paler coloration of the leaf is not botanically important, 

 and is, of course, in correlation with the absence of red in the flower ; 

 while the obtuseness of the leaf-segments, above referred to, can also be 

 found in G. Jamesoni, though with less frequency. The inflorescence is 

 quite identical, except in the yellow colour of the ray-florets ; but this is 

 strongly in contrast with the flame-red of G. Jamesoni. 



" The seeds of this novelty were sent to me fifteen months ago by Mr. 

 W. R. Adlam, with the request that the plant, if new, should be named 

 after Sir Michael Foster. A specific distinctness was, I think, in view ; 

 but though this fails, and even the position of botanical variety, I have 

 still the pleasure of carrying out Mr. Adlam's request in the English form 

 of name properly adopted for good variations of similar degree. This, 

 indeed, may be the first of a series of variations which can no doubt be 

 obtained by crossing. I am hoping, too, for good results from hybrids I 

 have made between G. Jamesoni and a quite distinct species with white 

 flowers which is more easily grown, but in itself is not so fine. The beauty 

 of Gerbera ' Sir Michael,' or G. Jamesoni * Sir Michael,' may be imagined 

 when I mention that the first flower-head on a seedling plant, with stalk 

 about a foot high, was 3| inches in diameter, equal in form to the finest 

 G. Jamesoni, and of the purest possible colour. The seeds were gathered 

 near Barberton, in the Transvaal, at an altitude of from 2,000 to 3,000 

 feet." 



Mr. Lynch also sent Plectrajitlius saccatus, a new introduction to 

 Cambridge, the flower being exceptionally large for the genus ; it was 

 received from the Cape. Lotus glaucus, Ait. (referred to in Journal of 

 Botany, 1897, p. 382). Pancratium canariense. Lindenbergia grandiflora, 

 introduced to Cambridge, 1900 {Bot. Mag. 1900, t. 7,738), Nat. Ord. 

 Scrophularinece. The genus embraces eight species — E. Africa, Arabia, 

 India, and Malay Arch. The present species has yellow flowers, re- 

 sembling those of Mimulus, but is devoid of the two sensitive stigmatic 

 lobes, the stigma being globular. 



Plants from Botanical Gardens, Trinity College, Dublin. — Mr. F. W. 

 Burbidge, V.M.H., sent the following for exhibition : Colletia Bentham- 

 iana , a plant of dwarf er and finer growth than C. ferox ; it bore three 

 leaves upon the spines. Bubus australis, in three forms, viz., var.
