  • BULL THISTLE (Cirsium Vulgare) Description
    BULL THISTLE (Cirsium vulgare) Description: Bull thistle, also referred to as spear thistle, Fuller’s thistle and lance-leafed thistle, is a member of the Asteraceae or sunflower family. Bull thistle can grow 2 to 5 feet tall with numerous spreading branches. Stems of the plant are sparsely hairy, irregularly and spiny winged, green or brownish in color with purple veins. Leaf margins are double dentate (toothed and toothed again), each ending in a lone stiff spine. The leaf surface of the plant has a distinct center vein with slight pubescence on the topside and more underneath. Flower heads are usually solitary on the end of each stem, gumdrop-shaped, one to two inches tall with long, stiff, yellow tipped spines. Flowers are generally bright purple but sometimes white in color. Seeds are light-colored with dark brown to black longitudinal stripes. Seeds are generally 1/16 inch long, oblong, somewhat flattened or curved, with a long, white, hairy plume. Plant Images: Bull thistle Rosette Leaf Gumdrop-shaped flower Distribution and Habitat: This thistle is generally found in the northern and eastern counties in North Dakota and is the least serious of the introduced thistles in the s tate. The plant thrives in moist soils and is less common on sand and pure clay soils. Typical habitats include disturbed or degraded land, such as roadsides, fence rows, overgrazed pastures and rangelands, eroded gullies, ditch banks and vacant lots. Life History/Ecology: Bull thistle is a biennial that reproduces and spreads solely by seed production. Germination of the plant occurs in the spring or during the fall in response to adequate soil moisture.

O'Leary State Herbarium of South Australia, Plant Biodiversity Centre PO Box 2732, Kent Town, South Australia 5071 Email: [email protected] Abstract A new species, Acacia toondulya, is described and illustrated. It has a restricted distribution in the western Gawler Ranges, Eyre Peninsula, South Australia and is most closely related to A. notabilis. Introduction The taxon described here as A. toondulya was first collected in 1969, and again in 1972. These specimens were identified as A. beckleri and A. notabilis due to their large phyllodes and flowers, or pods with transverse seed. A specimen collected from Toondulya Bluff in 1981 with a distinct pruinose coating on its branchlets and racemes (but in young bud) at first remained undetermined for some time and then finally identified as A. cretacea. At this time a study of the biology of A. cretacea was being conducted by the Conservation Biology Unit at the Black Hill Flora Park, and with earlier reports of populations of A.
