Some Observations on the Genus Kubus. lo" 



grows in more places in our country, than in any other European country, 

 although, every where, it is very scanty, and probably has already disappeared 

 t'rom several loealiries. It has been met with at Kosta and Alnön, in Medelpad, 

 in the north of Sweden, at Stockholm, at Magniberg, near Nyköping, at Tånge- 

 stad, in the parish of Dagsberg, in Östergötland (Mr. Kindbeug in litt), on 

 Pämö, near Carlskrona; all these localities are in the eastern part of the country. 

 It is further to be found in the West, at Hvarf, in Westergötland, at Norum, 

 in Bohuslän; and in Norway, at Christiania and Skien. The scandinavian, like 

 the German form, has almost unarmed turiones. Still the turiones on the 

 form from Medelpad are furnished with many setaceous, purple prickles. One 

 or other of the upper leaves on the turiones can !>e simple, cordate. 



With the exception of this very curious variety, R. idreus has not produced 

 any very remarkable varieties in this country. Arrhenius (1. c. page 13) 

 describes a variety maritimus, the distinguishing characteristics of which are 

 to be attributed entirely to local influence. It grows on places inuch 

 exposed to the sea-winds. A moditication ot this variety, distinguished by its 

 extraordinarily numerous, fine. deflexed prickles, also small lanceolate leaflets, 

 has been sent to me from Carlshamn, in Bleking, by Mi-. R. Wallengren. 

 The typical var. maritimus is distinguished by its broad, ovate leaflets. A 

 form distinguished by its small lanceolate leaflets, and unarmed turiones. has 

 been observed in the north east of Skåne, near Breanäs. I have remarked, in 

 this form, the uncommon circumstance that both the lowest pairs of leaflets on 

 the leaves of th< j turiones, when they are septenate, rise from the same point, 

 swhile the upper pair that answer to the two upper leaflets on quinate leaves 

 it near the terminal leaflet. One of my pupils, Mr. G. Andersson, has disco- 

 vered another peculiar form, in the neighbourhood of Stehag, in Skåne. It is 

 distinguished by a regularly cordate, ovate terminal leaflet on the turiones, which 

 is quite like that of R. suberectus. Also the terminal leaflet on the flowering- 

 shoots is cordate, ovate. Mr. N. C. Iyindherg has kindly written to 

 nie, that on the sea shore at Manhem, in Östergötland, a form grows that 

 has yellow <,n - een flowers; it is probably Abbhenius's variety maritimus, which 

 is likewise distinguished by yellow green petals. Mr. Kindberg has also in- 

 formed me of a form, with amber-coloured fruit, which grows in one or two 

 places in Östergötland, viz, Ringarum and Kisa.
