Red Raspberry, Rubus strigosus. Leaves all simple (palmately lobed), mostly (7–) 9–22 cm or more broad; petals 18–25 mm long; fruit readily separating from receptacle; plant with erect woody stems and shreddy bark. 7. Range: Across North America. Each photo represents one species in this genus. 10–14 (–18) mm long; flowers solitary on glandless pedicels; leaflets nearly or quite obtuse to rounded at apex. Stem habit (e.g., ascending, doming, trailing) must be assessed on primocanes from the summer and fall (i.e., during or after flowering on the floricanes) for two important reasons. Compared to other foveavirus species, the RdRp protein showed the highest sequence identity (45.3 %) to the RdRp of peach chlorotic mottle virus (PCMV) while the maximal sequence identity for the CP protein was 33.9 % with grapevine rupestris stem pitting-associated virus … 2. Rubus subgenus Other Rubus species utilized to produce these hybrids include R. ursinus, R. ulmifolius [R. inermis], and R. alleghaniensis. There is also an American species, Rubus strigosus – the American red raspberry. 15. Further, preliminary work examining types suggest that some of these synonyms were incorrectly placed by them. Pedicels and peduncles with gland-tipped ± straight bristles; mature fruit red, without tomentum between the druplets. Native Introduced Native and Introduced. Those in the Leaflets (all or many of them) pinnately lobed or ± incised nearly or quite to the midrib, besides the usual teeth; calyx lobes armed with firm prickles. At the other extreme are treatments that recognize a multitude of species, these often based on a single difference, such as more pointed leaflets or a more compact inflorescence (e.g., Davis et al. See list of 4 In the key, distinguishing the types of stems is very important. species in 5b, See list of 5 Character states were coded for numerical analysis. in 26a, See list of 4 11 Comments. Range: Western North America, from Alaska to northern Mexico R. flagellaris, 2020 Leaflets glabrous beneath (or a few hairs only on principal veins); old canes with few or no prickles (though new growth usually has a few).

Raspberry - Rubus idaeus Identification & Cultivation: Raspberries, commonly known as red raspberries or European raspberries, originate from Europe and Northern Asia. 9. These can drape over other plants and down banks, and arch through shrubs, but in neither case do these actually climb and they are here all considered shrubby. Some Rubus such as R. flagellaris, are strong trailers, and others, especially R. occidentalis, may develop long, arching, tip-rooting primocanes. you. in 28b, See list of 2 Drupulet Color: bright red. species Many hybrid combinations between species of blackberries have been noted. The Plants Database includes the following 244 species of Rubus . Petals deep rose-pink, ca. We hope you enjoyed this guide to blackberries of the world! Pedicels and calyx with conspicuous, abundant purplish stipitate glands, the longer ca. Pedicels and axis of inflorescence (also petioles and young growth) with conspicuous stalked glands; leaflets pubescent beneath. Leaflets pubescent beneath (between the principal veins) or canes strongly armed (or both conditions present). in 2b, See list of 25 Your help is appreciated. 1. species 15. Show photos of:   Petals white; calyx lobes with yellow-orange very short gland-tipped hairs; from the Upper Peninsula south to Alpena Co., mostly close to the Great Lakes. in 29b. Rubus allegheniensis × Rubus hispidus → This rare blackberry hybrid is known from MA, ME, NH, VT. species Go Botany: Native Plant Trust Some taxa are sexually reproduced and others are apomicts. 1967, 1968a, 1968b, 1969a, 1969b, 1970). These are the dewberries and blackberries, a challenge to the botanist in more than one way. Terminal leaflets widest above middle, obovate to broadly rhombic, the apex obtuse to rounded; stems with slender prickles only; petals deep rose-pink. Thimbleberry (Rubusrosifolius Sm.) species describe similar species. Range: Extreme south of South America. Rubus parviflorus Nutt. 10. species It is marked by variably oriented primocanes (erect, doming, or trailing) armed with both short, stiff, curved prickles (but usually thinner than in typical R. allegheniensis ) and stipitate-glands, subcoriaceous and lustrous, ovate to elliptic leaflets that are pubescent abaxially, Canes armed with bristles or slender narrow-based prickles; plants relatively low, even well-developed ones scarcely 1 m tall. in 13b, See list of 16 Identification and molecular characterization of a novel foveavirus from Rubus ... and CP genes, respectively. Leaflets merely toothed, at most shallowly lobed; calyx lobes unarmed (may be glandular-bristly). The fruit in Rubus is an aggregate of numerous small juicy druplets (each from a separate carpel of the flower); the receptacle on which these are inserted is fleshy and falls with the fruit in the dewberries and blackberries, but is firm and remains on the plant in the thimbleberries and raspberries. Pedicels and calyx with stipitate glands inconspicuous, yellowish, mostly 0.2–1.5 mm long, mostly shorter than the bristles. ... Due to frequent hybridization and introgression events, identification of Rubus species can be challenging (Davis, 1990; Johnson and Hoagland, 1999). Floricane prostrate or trailing, slender, the flowering shoots arising ± perpendicularly from the essentially horizontal cane; primocanes ± ascending or trailing, rooting at the tips. in 6b, See list of 3 Berry Flavor: tart . Pedicels and other parts glandless or nearly so; leaflets glabrous or pubescent beneath. in 2a, See list of 2 Primocanes are the first-year stems and are green for the first half of the growing season, later forming winter buds at the tip. is presented, together with a complementary identification key following the plant system. Stems with prickles, or at least bristles (rarely completely smooth in the erect R. canadensis); leaves all or mostly compound. Notes on the habit of the plant are important: whether the stems are erect, ascending, arched, immediately prostrate, or trailing (starting upward but soon back on the ground), and whether they root at the tips. 2. 13. 11. species in 18b, See list of 2 14. Floricanes are the second-year stems and are usually red or red-brown to purple or purple-brown and frequently have dead tips (i.e., no buds). Over 400 so-called species have been described from eastern North America, most of these now regarded as apomicticly reproducing clonal lines. in 22b, See list of 2 MA by Kartesz (1999), but specimens are unknown and the record is likely erroneous. Three sets of native species pairs keyed out at the beginning, Rubus odoratus and R. parviflorus, R. acaulis and R. pubescens, and R. occidentalis and R. strigosus are normally all diploid and are fairly clear-cut, although hybrids exist between the members of each of the pairs. Comment below if we missed one of your favorite species and we’ll add it in. species in part by the National Science Foundation. in 9a, See list of 2 (1968) and Floraweb (2003). Followed here is Hodgdon and Steele (1966), a treatment of intermediate nature that provides names to some of the variation seen on the New England landscape. Floricane leaves densely white-pubescent beneath; fruit red or black at maturity, readily separating from the receptacle (except in R. bifrons). Rubus geoides. Petals white; fruit readily separating from the receptacle; primocane leaves pinnate. Almost all species of Rubus are agamospecies, segregated from R. fruticosus L. Many of these species arose during the Pleistocene era as a result of hybridization and apomixis (reproduction by seeds which develop without sexual fusion; Tutin et al., 1968).
