NOTES ON THE BOTANY OF NORTHERN PORTUGAL. 179 



Primus lusitamcas L., and a little further on Yincetoxicum nigrum 

 Mch. At N. S. do Desterro a fine Verbascum grows abundantly; 

 I believe it to be V. Henriguezii Lauge. About Subagueiro (a most 

 filthy village) such plants as Linaria sapphirma Hffgg. Ok., Peribattia 

 hispcmica Trim., Cynosurus echinatus L., and Festuca Henriquedi 

 Hack, were frequent ; and here also I first saw the curious His- 

 pidella hispanica Lam. 



The next day we reached the higher ground in the neighbour- 

 hood of the "lakes" — small mountain tarns. Here the countless 

 pools were full of a Batrachian Ranunculus very closely allied to B* 

 hololeucos P. Sz. It has been described as a distinct species by 

 Freyn, under the name of J*. lusitaniens. More rarely we came on 

 a pool choked with the rare and pretty grass, Antinoria agrostidea 

 ■Pari. Rocks produced Saxifraga umbrosa L., and very sparingly 

 Campanula Herminii Hffgg. Lk. This should have been abundant, 

 but the sheep had been before us. Fortunately they had spared a 

 tiny Umbellifer which I detected in one spot. I saw only a few 

 plants, and supposed it at the time to be a Gonopodium. It proves, 

 however, to be Buiinia bunioides Bss., a very rare plant hitherto 

 known only from one or two localities in Spain. Then, while we 

 rested, one of the men was sent to explore the rocks above us. He 

 returned with a supply of Smecio caspitosu* Brot. 



Next day we tramped over miles of Plantago subulata L. var. 

 yranatensis, but saw little else, except a Hieracium near mm urn, 

 which, I understand, may be //. cinerascens Jord. The only other 

 hawkweed I saw on the serra was H. castellanum B. K., a species 

 allied to our H. Pilosella L. Three species of Genista brought in 

 by one of our men (G. lusitanka L., G. dnerascens Lge,, and G. 

 polygalafolia DC.) may complete the list of our Estrella spoils. 



Lastly, a few words about Coimbra. Here I found myself on 

 limestone, and of course the difference in the vegetation was very 

 marked. But I had little opportunity for investigating it, nearly 

 all my time being spent in the herbarium of the University. I 

 cannot speak too highly of this, nor of the kindness of every one 

 connected with it. I was most generously assisted both by in- 

 formation and by the gift of specimens, and I beg to tender my 

 *aost grateful thanks to Prof. Henriquez and the members of his 

 staff. 



During the short walks for which I was able to find time 

 I gathered, among other plants, Planiago Lagopns L., Jasmimm 

 fruticans L., Campanula primulafolia Brot., Smila.v mauritanim Dsf., 

 Pimpinella villosa Schomb., Buplmrum panicfdatum Brot., two or 

 three species of Centaur ea, the allied Microlonckus mlmaniicus DC., 

 Bourgaa humilis Coss., and Acanthus moUis L. A little earlier in 

 the year the old walls about the city would have afforded good 

 botanising ground ; as it was, I was glad to collect Antirrhinum 

 ktifoUwn DC, and a Micromeria, probably M. gro \ Bth.
