Erect Silky Leather Flower

Clematis coactilis (Fernald) Keener

Comments

provided by eFloras
Clematis coactilis is known only from western Virginia. C. S. Keener (1967, 1975) suggested that this species may be a stabilized derivative of past hybridization between C. albicoma and C. ochroleuca .

In fruit, Clematis coactilis is distinguishable from C. ochroleuca by its combination of spreading to reflexed hairs on the achene rims and whitish to pale yellow (rarely tawny) hairs on the beaks, contrasting with the strongly ascending hairs on the achene rims and tawny (rarely yellowish white) hairs on the beaks of C. ochroleuca . This species and C. ochroleuca lack stomates on the adaxial surface of the leaves, whereas the closely related species C. albicoma , C. fremontii , and C. viticaulis have stomates on both leaf surfaces (C. S. Keener 1967).

Clematis coactilis

provided by wikipedia EN

Clematis coactilis, common name Virginia white-hair leather flower,[2] is a plant species endemic to the western part of the US State of Virginia. It is reported from only Botetourt, Roanoke, Craig, Montgomery, Giles, Wythe, and Pulaski Counties.[3] It is usually found on soils formed from shale, less often dolomite, limestone or sandstone.[4]

Clematis coactilis is a shrub, not a vine like many of the other members of the genus. It is erect, up to 45 cm tall with silky, bristly or woolly hairs. Leaves are thick and leathery, simple but sometimes lobed, up to 12 cm long. Flowers are bell—shaped, borne one at a time at the tips of branches, pale yellow sometimes with a purplish tinge. Achenes are hairy, with a feathery beak up to 6 cm long.[4][5][6][7]

クレマチス・コアクチリスClematis coactilis)はセンニンソウ属の一種。

アメリカ合衆国バージニア州の西北部に広く分布する。花弁をもたず、花弁のように変化したを持ち、原種は花も小さく、花色も限定され、白に近い淡黄または、薄い紫の色が入った種も確認されている。チューリップ咲き(釣鐘型)、その表面に多数の綿毛をはやす。結実後、種子の先端に状の突起がある。葉は、細長いスペードまたはハート形で対生である。交配により半つる性の存在も確認されているが、原種は直立形が原形である。

園芸品種の特徴[編集]

クレマチスは大きく分けて、つるを残し越冬する旧枝咲き、新旧両枝咲きと地上部が枯れ翌年に新枝を伸ばす新枝咲きがあるが、コアクチリスは冬季に地上部の殆どが枯れ翌年春に新枝を伸ばす新枝咲きである。園芸品種としては主に種子による実生、または株分けにより繁殖させる手法をとるが、最近はクレマチス用の発根促進剤、植物成長調整剤により容易になっている。
