ON THE FLORA OF TIREE 37 



on many plants, and to Messrs. H. and J. Groves, who have 

 examined all the Characece. 



THALICTRUM DUNENSE, Dum. Very common on sandy places 

 bordering the shores. 



RANUNCULUS TRICHOPHYLLUS, Chaix. Messrs. H. & J. Groves have 

 so named specimens from two localities near Scarinish. 



RANUNCULUS DROUETII, Godr. Common in streams and ditches, 

 varying considerably in habit, length of peduncle, and size ot 

 flowers. 



RANUNCULUS BAUDOTII, Godr. Common about Loch Vassapol 

 and in its exit stream. 



Var. c. MARINUS, Fr. Stream at Hynish Bay. This is the 

 only authentic record for this plant in Scotland ; I am 

 indebted to Mr. Bennett for identifying the Batrachian 

 Ranunculi. 



RANUNCULUS FLAMMULA, L. Very common in wet places. 



RANUNCULUS ACRIS, L. Very common as var. Borceanus, Jord., 

 over all the island, except on the central moorish ground. On 

 the sandhills it frequently has a vertical rootstock of from five 

 to six inches in length. Another form, R. Steveni, Andrz., 

 also occurs on sandhills, but not in any quantity. 



RANUNCULUS REPENS, L. Very common about roadsides and ad- 

 joining ditches ; also at sides of cultivated fields. 



RANUNCULUS BULBOSUS, L. Common in sandy pastures. This 

 species, which is also common in Coll, is very rare on the West 

 Coast mainland north of Loch Linnhe, the only locality where 

 I have seen it being on a sandy pasture near the shore in 

 Ardnamurchan. It is found in the Outer Hebrides. 



RANUNCULUS FICARIA, L. Leaves of this plant are to be seen 

 quite commonly, even in summer, among shady rocks. The 

 Rev. D. Maclean sent me fresh specimens in spring with the 

 remark "quite common in Tiree." I also found it fruiting, 

 which is not uncommon for the species on this coast. A 

 considerable percentage of plants have flower heads that form 

 fruit ; but frequently only a few achenes ripen on a head. 

 When the achenes commence to swell the peduncle arches, as 

 the head endeavours to reach the soil, thus making the fruiting 

 inconspicuous. 



CALTHA PALUSTRIS, L. Very common at the sides of ditches, 

 marshes, and lochs. 



PAP AVER RHCEAS, L. Very rare; only one plant seen in 1 897 in a rye- 

 grass field belonging to the Hotel ; none seen the previous year. 



PAPAVER DUBIUM, L. Very rare ; a few plants in a cornfield near 

 Cornaig.
