Brassica napus L.

Brassica napus plant

Family - Brassicaceae

Stems - To +80cm tall, bluish-green, glabrous, glaucous, herbaceous, erect, branching above, typically single from base, from taproot.

Leaves - Alternate, sessile, glabrous, glaucous. Basal leaves lyrate-pinnatifid, dentate, to +15cm long. Auricles rounded. Cauline leaves sessile, clasping, auriculate, reduced above, to 9cm long, 3cm broad. Auricles rounded and broad.

Brassica napus leaves

Inflorescence - Terminal racemes, compact in flower and elongating in fruit to +30cm. Pedicels 6-10cm long in flower, elongating in fruit to +3cm and eventually at or near perpendicular to the axis of the inflorescence, glabrous, glaucous.

Flowers - Petals 4, yellow, clawed, glabrous. Claw to 5mm long, pale yellow to whitish. Limb to 5mm long, 4mm broad, rounded to blunt at apex. Stamens 6, 4 larger and 2 smaller (the two smaller stamens opposite and outside of the larger stamens). Filaments to 7mm long, glabrous, yellow-green. Anthers yellow, 2mm long. Ovary glabrous, green, terete, 4-5mm long. Style 1.7mm long, persistent in fruit. Stigma capitate. Sepals 4, 6-7mm long, to 2mm broad, linear, glabrous, yellow-green, erect to spreading, often with revolute margins. Siliques to +6cm long, terete, ascending and almost parallel with the axis of inflorescence, beaked, glabrous. Beak to 9mm long.

Brassica napus calyx Calyx.

Brassica napus flowers

Flowering - April - September.

Habitat - Roadsides, railroads.

Origin - Native to Eurasia.

Other info. - This is the species plant which gives rise to the Rutabaga. Chromosome numbers show that, originally, the plant was a hybrid between B. campestris L. (Turnip) and B. oleracea L. (Cabbage, Broccoli, etc.).
B. napus is not commonly found wild in Missouri but is beginning to spread throughout the state.

Photographs taken off Highway 9, Platte County, MO., 5-2-00.

Brassica napus L. var. napobrassica (L.) Peterm.

Rutabaga

Brassica napus plant

Family - Brassicaceae

Stems - To 1.5m tall, herbaceous, branching, erect, reddish-purple below, greenish-red above, glabrous, from large thickened taproot to +10cm in diameter.

Brassica napus stem

Brassica napus calyx Calyx.

Brassica napus flower Flower close-up.

Flowering - April - September.

Habitat - Cultivated and escaped to waste places, roadsides, railroads.

Origin - Native to Eurasia.

Other info. - This is the commonly cultivated rutabaga enjoyed by many. The plant is actually quite nice to look at. Turnips ( B. campestris L. ) resemble rutabagas but the roots are flat across the top.

Photographs taken off Hwy 29, Pike County, AL., 2-26-05.

4. Brassica napus Linnaeus, Sp. Pl. 2: 666. 1753.

Canola, oilseed rape, rape, rapeseed, rutabaga, swede, swede rape, Swedish turnip

Brassica napobrassica (Linnaeus) Miller; B. napus var. oleifera de Candolle; B. oleracea Linnaeus var. napobrassica Linnaeus

Annuals or biennials; (taproot slender or swollen); (glaucous), glabrous, glabrescent, or pubes-cent, (trichomes coarse). Stems branched distally, 3-13 dm. Basal leaves (rosulate when biennial); petiole (often winged), to 15 cm; blade lyrate-pinnatifid, ± pinnately lobed, 5-25(-40) cm × 20-70(-100) mm, lobes 0-6 each side, (smaller than terminal), surfaces (glaucous), glabrous or sparsely hairy when immature, glabrescent, or, rarely, pubescent. Cauline leaves (middle and distal) sessile; blade base auriculate or amplexicaul, (margins entire). Racemes not paniculately branched, (buds overtopping or equal to open flowers). Fruiting pedicels spreading to ascending (slender), 1-3 cm. Flowers: sepals (5-)6-10 × 1.5-2.5 mm; petals golden or creamy to pale yellow, broadly obovate, 10-16 × (5-)6-9(-10) mm, claw 5-9 mm, apex rounded; filaments (5-)7-10 mm; anthers 1.5-2.5 mm. Fruits spreading to ascending, smooth or slightly torulose, terete, (3.5-)5-10(-11) cm × (2.5-)3.5-5 mm; valvular segment with 12-20(-30) seeds per locule, (3-)4-8.5(-9.5) cm, terminal segment usually seedless, rarely 1 or 2-seeded (attenuate-conic, thin), (5-)9-16 mm. Seeds dark brown to black, light brown, or reddish, 1.8-2.7(-3) mm diam.; seed coat finely reticulate-alveolate, not mucilaginous when wetted. 2 n = 38.

Flowering May-Sep. Roadsides, disturbed areas, waste places, cultivated and abandoned fields, escape from cultivation; 0-500 m; introduced; Alta., B.C., Man., N.B., Nfld. and Labr., N.W.T., N.S., Ont., P.E.I., Que., Sask.; Alaska, Ariz., Ark., Calif., Colo., Conn., Del., D.C., Fla., Ga., Idaho, Ill., Ind., Iowa, Ky., La., Maine, Md., Mass., Mich., Miss., Mo., N.H., N.J., N.Y., N.C., Ohio, Okla., Oreg., Pa., Tenn., Utah, Vt., Va., Wash., W.Va., Wis.; Europe; Asia; Africa; introduced also in Mexico, Central America, South America, Atlantic Islands, Australia.

Brassica napus is both a crop and a sporadically occurring naturalized weed in North America, grown in two forms recognized by some as subspecies. Subspecies napus (rape, rapeseed, or canola) is an annual with slender roots widely cultivated as an oil crop and is the most commonly naturalized. Subspecies rapifera Metzger [= subsp. napobrassica (Linnaeus) Hanelt] (rutabaga, swede, or Swedish turnip) is a biennial with fleshy roots that rarely escapes from cultivation.

Although Brassica napus has been reported as a weed from most southeastern states, it is very likely that most reports represent misidentifications of B. rapa (I. A. Al-Shehbaz 1985). It is difficult to distinguish between plants of B. napus and B. rapa that lack flowers and proximal leaves.

Brassica napus is an allotetraploid derived from hybridization between the B. oleracea complex ( n = 9) and B. rapa ( n = 10). Its center of origin is uncertain but likely Mediterranean Europe, with molecular data supporting evidence of multiple independent origins between the parental taxa B. oleracea and B. rapa and its related n = 9 species (Song K. et al. 1993). Specimens from West Virginia have not been observed.
