serration, simple or compound, nor the presence or absence of 

 glandular hairs on the sepals pr peduncles. These characters 

 indicate only modifications of the same primary type. He agrees 

 with Matsson in designating such modifications by the prefixes 

 per, pra, suh, suiter, and ob. To these Almquist has added 

 hirtelli, tersi, and hirti. The primary has the leaflets simply 

 serrate or nearly so ; a per-form has the leaflets biserrate ; an ob- 

 form has glands on the margin of the sepals; sub and super 

 forms have glands on the backs of the sepals, the former with 

 simple, the latter with biserrate serration. A per-form with the 

 margin of the leaflets very glandular becomes a prae-form. A 

 hirtelli form indicates a transition to B. glauciformis. Tersi is 

 applied to a form of B. glauciformis, hairy only on the nerves ; 

 hirti to one more or less hairy over the surfaces. 



By the use of these prefixes, dealing with the innumerable 

 forms is greatly simplified. It has been found possible to class 

 the Scandinavian forms of B. glauca into thirty-four subspecies 

 and those of B. glauciformis into thirty-one, both with a good 

 many varieties. The author has not been content to describe the 

 types as detached from each other. His aim is to group them 

 according to resemblance or relation based on the above-mentioned 

 characters. In accordance with his view as to the relation 

 lietween glabrous and hairy species, the groups and subgroups 

 are common to B. glauca and B. glauciformis. 



It appears from the above that we have here a completely new 

 method of classifying roses, based on natural principles. 



SHOBT NOTES. 



Orobanche Eitro Gren. & Godr. var. hypoch^roides. — This 

 very beautiful Orobanche, conspicuous for its pure yellow colour, 

 is parasitic on Hijpocliaris raclicata and other composites at 

 St. Ouen's Bay, Jersey (see Journ. Bot. 1907, 425, and Rep. Bot. 

 Exch. Chib, i907, 258), where the Rev. L. V. Lester-Garland 

 showed it me in 1906, when I at once saw that it did not belong 

 to the 0. minor section. Dr. Beck puts it as a forma under 

 Grenier and Godron's plant, which is only recorded from the 

 vicinity of Marseilles, where, as its name suggests, it is parasitic 

 on Echinoi)s Bitro ; but it appears to me sufficiently distinct to 

 warrant the varietal rank which I have given ft. An examination 

 of Mr. Hanbury's herbarium shows that he gathered it in the 

 eighties in the same place, and that it was then named, I believe, 

 by Mr. Arthur Bennett as 0. minor var. fiavescens Renter. Still 

 earlier examples are in the Boswell herbarium, collected by Syme 

 himself in 1866, labelled "I think from the Grand Havre, but a 

 ticket says St. Ouen's Bay, possibly misplaced." Doubtless 

 Syme's memory was faulty, and the ticket gives the correct 

 habitat, as at present I have no evidence for its occurrence in 

 Guernsey. We may therefore safely delete 0. minor Sm. var. 

 fiavescens Renter from my List, as it is synonymous with the
