266 AZOREAN FLORA. [September, 



Isolepis fluitans. Callitriche verna. Polygonum Persicaria. 



Scirpua maritimus. Euphorbia Peplis. Plantago Corouopus. 



Eleocharis palustris. Euphorbia Lathyrus. Plantago major. 



Cyperus longus. Parietaria officinalis. Plantago media. 



Potamogeton natans. Chenopoclium urbicum. Plantago lanceolata. 



Potamogeton pectmatus. Clienopodium murale. Plantago Lagopus. 



127 vascular plants are common to the Azorean and British 

 Isles. Some of them are among the most common^ some the 

 scarcest. 



The following Azorean plants are peculiarly interesting, either 

 being peculiar species or else belonging to well-known genera : — 



Of the order Ulvace^ there is in this Flora (Hochstetter's) a 

 figure of Bryopsis penicillata with a description, p. 9. 



In HEPATfCiE, Rhacotheca azorica, with figures and an ample 

 description. 



In JuNGERMANNiACE^, Gymnomitrion erythrorhizum. 



In Musci, Hypnum Hochstetteri. 



In FiLiCEs, Alantodia, var. azorica. 



In Lycopodiace^, Lycopodium cernuum. 



We omit the Graminea and Cyperacea, etc., for want of room. 



Among the Orchids there are two Habenarias peculiar to the 

 Azores, H. micrantha and H. longibracieata. 



The following are probably desirable species, viz. Euphorbia 

 azorica, Urtica azorica, Plantago azorica, Scabiosa nitens, S. neg- 

 lecta. Bellis azorica and Solidago azorica are both interesting 

 species, especially the latter, which might be an ornament to the 

 shrubbery. Tolpis nobilis is truly a noble plant, and as it grows at 

 a great altitude, upwards of 3000 feet, is probably hardy enough 

 to resist our winter's cold. 



We should like to see specimens of Erythroea latifolia, from 

 St. Michael's and Terceira. 



E. diffusa is a species peculiar to these islands. Myosotis 

 murina is another desirable plant. Euphrasia grandiflora is an 

 elegant species, with rounded, singularly curled, rigid leaves. It 

 grows between 3000 and 4000 feet altitude, and has large, hand- 

 some flowers ; a fine plant for artificial rocks. 



There is a new Rubus, R. Hochstetterorum, and a new Rhamnus, 

 viz. R. latifolius, which has leaves five inches long and two and a 

 half broad. Hypericum foliosum, Ait., is another desirable species. 

 Cerastium azoricum, of which there are several varieties, might 

 be a useful plant.
