NOTES FROM A GARDEN HERBARIUM—II. 



and more bushy than the above, the leaves smaller and 

 more thickly placed upon the bush, persisting longer in 

 the fall ; leaves smaller, smooth or nearly so when full 

 grown, the leaflets ovate- 

 oblong and coarsely tooth- 

 ed ; inflorescence shorter, 

 iiearly smooth, scarcely or 

 not at all glandular, the 

 lower pedicels subtended 

 by small entire leaves, giv- 

 ing the cluster a leafy or 

 yVt^Wi/cJc" appearance ; flow- 

 ers smaller. The Early 

 Harvest belongs to this 

 variety. Fig. 2 shows the 

 essential characters of this 

 variety, when contrasted 

 with Fig. I. The coarse 

 dentation of the leaflets is 

 an important point, which 

 is commonly overlooked. 



Var. ALBiNUS, new var- 

 iety. [IV/iitc' Blackberry.) 

 Lower than the type, the 

 stems throughout green- 

 ish-yellow ; leaflets much 

 as in the var. frondosiis ia 

 shape and dentation, but 

 more or less hairy and 

 glandular ; inflorescence 

 long but bearing simple 

 bracts as in the last vari- 

 ety, hairy and glandular; 

 fruit small, creamy white 

 or amber-colored. I have 

 known this plant from 

 childhood. It grew spar- 

 ingly in the woods in 

 western Michigan, and it 

 was occasionally transfer- 

 red to gardens. In one 

 garden, at least, it has 

 grown for more than twen- 

 ty years, and it has always 

 retained its characteristics. 

 I suppose that the white 

 blackberries sometimes ad- 

 vertised by nurserymen 

 belong here, but I have no 

 specimens of them. 



The raspberries are gen- 

 erally placed in two divis- 

 ions, although these divis- 

 ions are by no means so 

 definitely marked as we 

 have been led to suppose : those propagating by sprouts 

 or suckers from the root, and those propagating by stol- 

 ons or root-tips. The characters of the inflorescence or 

 flower clusters are the most important distinguishing 



marks in our raspberries, although they have never 

 been given much prominence in the botanies. The 

 \Tirinus species, I think, are as follows ; 



RuBUslD^us,Linn. {^Eu- 

 ropean Raspberry .) Plant 

 usually stiff and erect, 

 the stems bearing nearly 

 straight slender prickles 

 or weak bristles, and usu- 

 ally light-colored ; inflor- 

 escence sub-corymbose — 

 the pedicels short, and ag- 

 gregated above, where they 

 are erect or ascending ; 

 fruit large and broad, ap- 

 pearing more or less con- 

 tinuously throughout the 

 summer, purple or yellow- 

 ish. The raspberries be- 

 longing to this species are 

 usually tender in the north, 

 and they have not been 

 grown to any extent since 

 the introduction to culti- 

 vation of the native species. 

 Here belong the Fontenay 

 and its kin. 



RuBus STRiGOSUs, Mich. 

 (AV(/ Raspberry .) Fig. 3, 

 p. 723. More slender than 

 Riibus Idceus ; stems, at 

 least in the wild plant, 

 densely clothed with, 

 straight and weak bristles, 

 usually brown or reddish- 

 brown ; inflorescence ra- 

 cemose, the peduncles 

 scattered, all slender and 

 drooping, either simple or 

 two or three-flowered, not 

 aggregated at the top, 

 smooth or bristly ; petals 

 as long as the sepals ; fruit 

 light-red, usually smaller 

 than in R. Idcrus. The 

 racemose character of the 

 inflorescence of thisspecies 

 is well shown in the Cuth- 

 bert (Fig. 3), a variety 

 which appears to closely 

 represent in all particulars 

 the true Rzibiis sirigosits.. 

 Hansell appears to be R. 

 slrigosiis also. The wild 

 plant is densely clothed 

 with weak bristles, but these mostly disappear in culti- 

 vation. They sometimes persist near the base of the 

 cane, and traces of them can be seen in the inflorescence.
