Sparganium angustifolium 線葉黑三棱

Common name: Floating Bur-reed
Scientific name: Sparganium angustifolium 線葉黑三棱
Genus: Sparganium 黑三棱屬*

Family: Typhaceae 香蒲科, cattail family

Note: Sparganium 黑三棱屬 is placed in Sparganiaceae 黑三棱科 in Cronquist system, of 1981. The APG II system, of 2003 (unchanged from the APG system, 1998), also recognizes this family. By the APG III system of 2009, Sparganium had been found to be fairly closely related to Typha 香蒲屬, and so was placed with that genus in family Typhaceae 香蒲科.

Remarks*: Cranberry 蔓越莓、越橘、蔓越橘、小紅莓 are a group of evergreen dwarf shrubs or trailing vines in the subgenus Oxycoccus 紅莓苔子組 of the genus Vaccinium 越橘屬.

In Britain, cranberry may refer to the native species Vaccinium oxycoccos. Although it is cultivated in central and northern Europe, most of the cranberry sold in UK supermarkets is Vaccinium macrocarpon 大果越橘, large cranberry, American cranberry or bearberry, which is a North American species of cranberry and is cultivated throughout the northern United States, Canada and Chile.

Prunus avium 歐洲甜櫻桃、甜櫻桃、大櫻桃、甜車厘子、車厘子

Origin:  native

Date:  13th April

[158] Suckering deciduous tree to 25 m.

[166] Branch.

[171] Upper trunk. Bark smooth, reddish brown?

[170] Middle trunk.

[168] Lower trunk. Bark peeling now.

[161_1] Leaves 6-15 cm.

[162_1] Leaves glabrous above. Red petioles with pair of reddish glands towards apex.

[163] Underside of the leaf.

[163_1] Enlarged photo above showing thinly pubescent beneath the leaf.

[158] Flowers in umbels of 2-6; base of inflorescence with large persistent green bud-scales.

Showing the inflorescence, the bud scales at the base and the arrangement of leaves. 

[160] Showing the inflorescence, the bud scales at the base and the arrangement of leaves. 

[167] Showing the inflorescence, the bud scales at the base and the arrangement of leaves. 

[157_1] Base of inflorescence with large persistent green bud-scales. Bud-scales (Bs) not leaf-like, at the base of flower stalk (Fk) (vs some bud-scales leaf-like in Pinus cerasus 歐洲酸櫻桃、酸櫻桃、酸車厘子, dwarf cherry)

The following structures could also be seen: Each young leaf (Yl) with a pair of stipules (Se) with glandular-dentate margins. Mature leaves would have pair of reddish glands towards apex in the petiole.

[158_1] Upper surface of bud-scales (Bs) could be seen above. Also, receptacle could be seen constricted at apex (see the above red arrow). (vs receptacle not constricted at apex in Pinus cerasus 歐洲酸櫻桃、酸櫻桃、酸車厘子, dwarf cherry)

[160_1] Showing the relative postions of green flower stalks (Fk), bud scales (Bs), red petiole (Pe) and stipules (Se).

[167_1] Enlarged photo showing the structure of a young leaf (yellow dashed rectangle). A pair of stipules (Se) are present at the base of a young leaf (Yl). Other structures could be seen are: bud scales (Bs), green flower stalk (Fk) and red petiole (Pe).

[157_2] Enlarged photo showing the stipules. They are small, slender structures located at the base of the leaf petiole. They are typically acuminate (tapering to a long point), linear, and possess glandular-dentate (toothed with small glands) margins. These stipules are often deciduous, meaning they fall off early in the season.

[159_1] Flower bowl-shaped.

[156_1] Receptacle constricted at apex (see the above blue arrow). (vs receptacle not constricted at apex in Pinus cerasus 歐洲酸櫻桃、酸櫻桃、酸車厘子, dwarf cherry)

[164_1] Petals had fallen off at this later stage of flower.
