a. Groves, thickets and pastures, frequent in Scotland.. j3. rare 



and chiefly on the mountains once covered by the Caledonian Forest 

 Eenchat, 5 m. N. of Blair Athole ; mountain N, of Loch Ericht ; and

Scales of the involucre oblong, shining with a broad brown border 

 Sir J. Smith in his Engl. Flora (iii. pp. 414 — 416.) has incorrectly 

 removed to our var, j8. those states of G, supinum which have spiked 

 or tufted sessile heads of flowers, 



3. G-. uliginosum L. (Marsh C) ; stem very much branched 

 diffuse woolly, leaves linear-lanceolate downy, heads in terminal 

 crowded tufts which are shorter than the leaves. E. B, t. 1194. 



Sandy and wet places; especially where water occasionally stands. 



0. 7,9. — A span high, much branched. Heads o? flowers 2 3 



together among the closely placed upper leaves small, sessile, formin 

 oblong clusters at the extremity of the branches. Scales of the 

 involucre yellowish-brown, shining, glabrous. 



*^* Filiform florets in a single row ; achenes compressed. Omalotheca. 



4. G. supinum L. (dicarf C.) ; ca?spitose, stem decumbent 

 branching only from the base, flowering-stems erect, heads 

 1 — 5, leaves linear downy on both sides. — a. heads rather 

 distant stalked. E. B. t. 1193. — /3, heads approximated 

 sessile. G. sylvaticum Sm. (partly). 



Summits of the Highland mountains, abundant. 2/.. 7, 8. Of 



our two varieties, ^. is by far the most common, and is that generally 

 known as G. supinum abroad ; while our a. or Smith's plant is the 

 var, 7. of Persoon. Achenes white from numerous short appressed 

 silky hairs, those towards the extremity being a little longer and 

 forming as it were a very short outQY pappns ; in G, sylvaticum, the 

 achenes are yellowish, sprinkled with a very few short hairs, and 

 when the pappus is removed a callous ring or disk is visible not 

 surrounded by a circle of hairs ; but the true distinction between 

 these two species consists in the form of the achene and number of rov/s 

 of the marginal florets,

32. FiLAGo Linn. Filaofo. 



^ Heads heterogamous, with one or more rows of filiform 

 pistillate florets in the circumference. Pappus pilose, of the 

 outermost row^ of pistillate florets very caducous or wanting. 

 Receptacle conical, with 1—5 rows of scales within or among 

 the filiform florets. Involucre imbricated, conical, of a few
