abortive states, as well as in Urceolarin scm.posa, and other Li- 

 chens having a tartareous, pale, friable thallus, I have detected, 

 by the microscope, octohedral crystals, apparently of oxalate of 

 lime, and in yonng specimens of Parmelia parietina, and other 

 species, acicular crystals, resembling the raphidian crystals of 

 phosphate of lime contained in the parenchymatous cells of many 

 of the higher plants. 



Endocarpon mimatum, var. uinbiUcatum and compUcatum, are 

 frequent on the face of the mm-al precipice of Kinnoull Hill, at 

 its lower part, but never attaining a diameter exceeding an inch. 

 Hooker, in his ' Flora Scotica,' mentions E. leptophyUum as oc- 

 curring " upon rocks on the hill of Kiunoull, near Perth.^' This 

 Lichen is probably only a subvariety of var. umbilicatum, which 

 I have just mentioned. Yai*. umbilicatum I have also found on 

 boulders on the banks of the Tay, frequently covered by the river, 

 below the famous salmon-breeding pond at Stormontfield. 



Several Callemas gi'ow in the same habitats as the Endocar- 

 pons, -^iz. on rocks which are either constantly or frequently 

 moist or covered bv water.

" Respecting Agrimonia Agrimonoides, I have to state that in 

 the border of a plantation, about seventy or eighty yards from 

 Kinfauns garden-wall, one plant of it was observed in flower 

 about the ndddle of Jime this year. Second locahty, near the vil- 

 lage of Rait, in the parish of Kilspindie, by the side of a hedge 

 surrounding a plantation : the number of plants observed might 

 be a dozen, and occupying an extent of four or five yards, and 

 distant from the manse (or minister's house) about sixty yards; 

 this was in the end of June this year. The plants were then in 

 flower. Rait village is near the old road from Perth to Dundee, 

 and ten or eleven miles distant fi'om either place. Thirdly, Scone 

 station : it is found in Scone TTood, from half to three-quarters 

 of a mile south-east of the palace, distributed over an area of four 

 or five acres, plentiful : observed also first in June this year. In 

 none of these locahties (as far as I am able to ascertain) was it 

 ever observed by any botanist before. The reason is obvious. 

 From its great similarity to Geum urbanum while in flower, it
