NOTES ON THE BOTANY OF NORTHERN PORTUGAL. 177 



a Gladiolus, apparently identical witli our New Forest plant ; Pota* 

 mogeton microcarpus Boiss. & Keut., for the determination of which 

 I am indebted to Mr. A. Bennett ; it seems, however, to be merely 

 a slight var. of P. polygonifolius. So far as the name goes, it is an 

 addition to the flora of Portugal. Gymnadenia conopsea E. Br., 

 a small patch near the top of Borrageiro — new to Portugal ; 

 Luzula lactea E. Mey., a close ally of L. nirea DC., is abundant in 

 the woods ; Ruscus acideatus L., Paradma Liliastrum Bertol., 



species of Liliacea.

The curious Cytinus Hypocistis L. was not uncommon on the 

 roots of Cistinere. Daphne Giddium L. was the only representative 

 of its genus: it is a very common plant in N. Portugal. Among 

 the higher rocks of Borrageiro Thymelcea cor idi folia Endl. was not 

 uncommon; here also I found Valeriana montana L., new to 

 Portugal. Among composites the most notable species are Pulicaria 



odora Rehb., Phalaerocarpum oppositi [folium Wk., and Crcpis lawpsa- 



noides Frol. All about Calnas the exquisite Campanula LoejUngu 

 Brot. is abundant ; in general appearance it reminds one of ( 

 pcitula, but is much handsomer. Ericacece are abundant and cha- 

 racteristic ; besides our common Call una and Dabeovia polifolia Don, 

 there are no less than six species of Erica, most of them exceedingly 

 common. Then we have the beautiful Thymus a pit id us Hffgg. Lk., 

 common all the way from Bouro to Caldas ; two or three species of 



Echiiim, Lithospermum prostratum Lois., Omphalodes lusitamca Pourr., 

 ScrophulariaHerijiinia'H.&gg. Lk., Linaria triornithophora'SVilld. 9 &c. 



Umbelliferse are not very numerous, but include the strange 

 Erynyium Duricenum Gay; while we are reminded of Cornwall by 

 finding Physospermum common in the woods near Caldas, and of 

 Ireland by Sa,rifraga umbrosa L. (this does not seem to vary at all 

 in Portugal). 



Crassulacem were represented by seven species, of which the most 

 remarkable were Sedum amphwivaule DC. and & brevifolium DC. 

 Lythrum acutanyulum Lej. was the only loosestrife observed. Rosacea 

 seem to be very poorly represented in Portugal ; I only saw one 

 rose in the Gerez district, a very beautiful canina-form with aciculate 

 peduncles, queried by Prof. Hennquez as var. fusiform** Wlk. Mr. 

 Baker, to whom I showed specimens, remarked that it approached 

 collina. The Rubi were more numerous, particularly near Caldas, 

 and by the track leading to Leonte. I should place them as 

 follows :— R. dhcoli>r Weihe (may I be pardoned for not following 

 the latest synonymic split?) ; locally common in the least elevated 

 Parts of the district ; apparently quite the same as the plant so 

 common in the South of England.— 11. Borreri Bell-Salt. Caldas, 

 rare. — R m tomentosus Bork. Sparingly on a bare stony hillside 

 exposed to the sun, not far from the Spanish frontier. — Rffut -at<r 

 Weihe (or very near to it). Caldas do Gerez ; apparently rare. I 

 gathered this also in one spot in the Serra da Estrella. Besid i 

 these, I found a bramble very commonly in the woods above 

 Caldas, which seems to differ from any hitherto recorded, I ven- 

 ture, therefore, to give the following description : —
