science is indebted for the discovery of the following hybrids at 

 Hyeres: — Orchis *Rainei Itouy (O. ChampagneuxiixO. saccatd) of 

 which I found a further specimen this year " Ophrys Rainei Alb. et 

 Jahand." (O. arachnites xO. bombylijiora) and O. olbiensis Godf. 

 ( O. arachnitiformisxO. Bertolonii). Last year she found, near 

 Hyeres, a single specimen ol Ophrys speculum Link, a North-African 

 plant. This was first discovered in France by Moggridge. who found 

 one specimen in 1865, and one the following year, near Menton. It 

 was not seen again till it was found at Les Salins by Raine in 1908, at 

 which place it has since been searched for in vain.

ON H1ERACIUM AURANTIACUM L. 

 By H. W. Pugsley, B.A., F.L.S. 



Among my pleasant memories of childhood is a bed of orange 

 hawkweed in my grandmother's garden which 1 suppose caught my 

 fancy through the striking colour of its Mowers ; and for the sake of 

 this association the plant, which of course is not uncommon in gardens, 

 has always had a place in my own small plot. Being thus familiar 

 with this hawkweed, 1 was rather surprised in the summer of 1916 to 

 notice in the grounds of the manse at Aviemore. Inverness-shire, a 

 profusion of a form which seemed to me distinct from ii\j plant, and 

 on my way home I met with this same strange form in cultivation 

 at Pepper Arden, in North Yorkshire, where it was remarkably 

 luxuriant. 



This form is not characterized by a constant abundance of long 

 leafy stolons by means whereof the plant rapidly spreads in all 

 directions, but produces intermittently shorter and mostly under- 

 ground stolons which effect a much slower increase. Its leaves are 

 larger, of a duller green, with shorter, stiffer, and more abundant 

 hairs, and in shape elliptical or obovate-lanceolate rather than 1 insu- 

 late or oblong. Its panicles, moreover, have fewer but larger heads 

 of an orange-red or brick-red colour instead of brownish orange. 

 These differences in habit, foliage, and flowers give the two forms the 

 aspect of two distinct species. 



On my return home in 1916 I saw by a reference to my herbarium 

 that in 1910 1 had collected this broad-leaved form, naturalized near 

 Galashiels, without appreciating its distinctness ; and a large propor- 

 tion of the British material in the National Herbarium at South 

 Kensington, gathered mostly in the north, also belongs to this 

 form.
