382 Dr Balfour's Description of Bare Platifs. 



low farina, similar to that on the leaves. Involucre polyphyllous, 

 leaflets (one of which is at the base of each pedicel) lanceolate, 

 from |- to f quarters of an inch long, and shorter than the pedicels, 

 which are from 1 inch to 1\ inch in length. Calyx gamosepa- 

 lous, 5- cleft, campanulato-tubular, covered with farina, its seg- 

 ments lanceolate-acute. Corolla yellow, ganiopetalous, salver- 

 shaped, its tube twice as long as the calyx, narrow about the 

 middle, and expanding in a somewhat campanulate manner to- 

 wards its union with the limb, wh.ere there is a maiked constric- 

 tion ; limb of an orange tint towards the centre of the flower, with 

 five grooves at the part where it joins the tube, having five seg- 

 ments, which are rounded, waved, somewhat crenate, covered with 

 minute capitate hairs. Stamens five, attached to the corolla, free 

 part of filaments very short, anthers opening longitudinally, in- 

 trorse ; pollen spherical. Ovary rounded, oblong, having an ap- 

 pearance of 10 teeth at its apex, indicating five bidentate car- 

 pels ; style round ; stigma capitate, obscurely 5-lobed, with a 

 depression in the centre ; placenta free, central, with numerous 

 rows of amphitropal ovules. 



Localities for Bare Highland Plants. 



The following observations were made during an excursion to the 

 Braemar, Clova, and Breadalbane districts in August 1847, a fuller notice 

 of which will ajjpear in the next Number of the Journal. 



1. Carex hporhxa, L., was picked near the summit cf Cairn Toul, between 



3000 and 4000 feet above the level of the sea. This is the second British 

 losality for the plant. It was also gathered in Dr Dickie's original lo- 

 cality on Lochnagar. 



2. Sonchus alpinus, L. (Muhjedium cdpinum, Less.), was found by Mr W. 



Douglas in profusion on Lochnagar, a locality in which it has not been 

 noticed since the days of Don. It grows on cliffs, which are not easily 

 accessible, and hence it has been jjassed over by botanists. This re-dis- 

 covery of one of Don's stations confiniis the opinion, that ultimately 

 those plants whicli have not been found since his day, such as Potentilla 

 tridenlata Itanunculus alpestris, &c., will yet reward the investigations 

 of botanists. 



3. Carex vaginata, Tausch., was found abundantly on everj' mountain in the 



Braemar and Clova district. It is particularly plentiful on llen-Aven 

 and Ben-na-Muich Dhui. 



4. Luzula arcuata, HooJ\, is also generally diffused on the mountains of that 



district, having been found on Lochnagar, Ben-Aven, Ben-na-Muieh 

 Dliui, Breriach, and Cairn Toul. 



5. Jlieracium villosum ? Sm., on Lochnagar. This is jierhaps //. alpinum, 



var., lonffifolium of the Flor. Kles. 



6. Woodsia hiiperhorea, Br., was pulled in Glen Isla, Glen Phee, and on Ben 



Lawers. 



7. Uijuisetum umhrosum, WiUd., occurred on the hills near Ballater. 



8. Orobus niijer, L., was found in profusion in the woods at the Pass of Kil- 



liecrankie.
