Preliminary remark: The genus Rubus is one of the most difficult! As 
all the characters are variable, too much importance should not be attached 
to any of them, but the aggregate of the characters, the habit, &c. should 
rather be observed. Then, in the first place it is well to examine only the 
constant and well-fructifying forms found in several places or in many diffe¬ 
rent places far distant from one another. In collecting, it is important to take 
a portion of the young shoot, from about the middle, with at least 2 leaves on 
it. Comp. Gremli, Beitrage zur Flora der Schweiz (1870); A. Favrat, 
“Les Ronces du Canton de Vaud,” in the Bull. Soc. Yaud. (1881); W. O. 
Focke, Synopsis Ruborum Germanise (1877); and, for the special study 
of Glandulosi, my article in the Oestr. botanische Zeitung (1871). 
1. Stem ann., 10—20 cm. Stipules free or hardly united to 
the petiole. Ls ternate, green underneath. Fr. red, gen. 
with only 2—5 drupels.—Mountain woods; distrib. 5 
saxatilis L. 634. 
— Stem gen. bienn.; the first year (the so-called “shoot”) 
it is gen. simple and only bears ls, in the second year 
it produces flower bearing branches*) in the axils of the, 
now gen. fallen, ls. Stipules springing from the petioles 2 
2. Ls pinnate with 5 (3—7) leaflets, the terminal one 
stalked. Fr. red covered with a persist, pubescence. 
Shoot erect-arched, cylindric, pruinose, gen. covered with 
numerous fine, dark-red aciculi. Leaflets white-tomen- 
tose underneath (the var. viridis A. Br. with leaflets 
green underneath has not yet been observed in Switzer¬ 
land). Stas short, almost 1-seriate. Raspberry.—Woods; 
distrib. 5 ...... Idseus L. 635. 
— Ls digitate with 3—5 leaflets, the terminal leaflet of a 
leaf with 5 leaflets is, rarely, itself 3-partite, thus making 
7 leaflets, but then the terminal leaflet is sessile. Fr. black, 
*) It is not unusual to find radical inflorescences, especially in Glan¬ 
dulosi, in cajsius and idseus, differing very much from the normal lateral in¬ 
florescences. These radical inflorescences are elongated, with many fls, and 
with leaves mixed with them.
