108 NEW SOUTH AMERICAN SPECIES OF POLYGALA. 



which I can only refer to a hybrid origin. All the species concerned 

 were deliberately introduced by myself, over four years ago, with 

 the exception of E. montanum, which I found well established, and 

 Fj. ohscunun, which grows close by. As the late editor of the 

 Supplement to Eni/Ush Botany, ed. 3, has expressed a strong 

 opinion against the occurrence of such natural " crosses," I think 

 it desirable to give a list of the hybrids which I consider to have 

 spontaneously arisen there, under my own observation, without any 

 interference on my part beyond the planting of the various original 

 species. By far the greater number of the seedlings, I may state in 

 passing, come quite "true." Specimens of the plants in the list 

 have, in most instances, been sent to S. Kensington for the British 

 Herbarium, where students may form their own conclusions : — 



E. adnatiim X Lami/i. E. lanceolaium x obscurum. 



,, X palnstre. ,, X pahistre. 



E. Lamyi x lanceolatum. ,, X roseum. 



E. lanceolatum X montanum. E. imrviflorum X roseum. 

 Probably two or three others might be added ; but I refrain 

 from doing this, as I feel some doubt about one of the plants in 

 these cases. The adnatum x iJalustre is a curious, narrow-leaved 

 form ; the only wild British specimen of this which I have seen was 

 collected in Monmouthshire by the Eev. A. Ley. The lanceolatum 

 X j)«^»sire is of still greater interest, as the only example hitherto 

 known occurred in a garden at Copenhagen. It has rather long- 

 petioled leaves, and a very glandular panicle. The two specimens 

 of this first appeared in 1893, and quite perplexed me ; owing to 

 the plague of Aphides, they did not develop properly, but last 

 summer was more propitious, and I succeeded in drying them 

 nicely. Though they approach E. palustre in many respects, their 

 affinity with E. lanceolatum (shape of leaves and stigmas, colour of 

 flowers, &c.) is equally clear. The palustre parent was a small 

 form from Ben More of Assynt, which I have apparently lost. In 

 these garden hybrids the capsules are uniformly slender and 

 shrunken, as compared with the true species. 



l^EW SOUTH AMERICAN SPECIES OF POLYGALA. 



By Alfred W. Bennett, M.A., F.L.S. 



In a parcel of Polijf/alacea;, chiefly from the Argentine Eepublic, 

 Bent me by Prof. F. Kurtz, of Cordoba, I find the following new 

 species of I'oh/yala. The sections of the genus referred to are 

 those adopted by me in my monograph of the Brazilian FohjjalaceoR 

 in Martius's Flora Brasiliensis.
