萼片的

Leaves narrowly lanceolate to linear-lanceolate, base cuneate; plants glabrous; epicalyx segments shorter than to equaling sepals.

叶狭披针形的到线状披针形，基部楔形；植株无毛；为了等于萼片的副萼片短于。 2 L。 virgatum 帚枝千屈菜

Floral tube (4 or)5-merous, campanulate, 1-2 mm; sepals (3-)5; epicalyx segments present between sepals, setiform, ca.

花被管(4或者)5瓣，钟状，1-2毫米；萼片(3-)5；副萼片在萼片之间宿存，刚毛状的，长约萼片的1/2或更长。

Although absent in most species, nectar may be produced in a spur (8) of the labellum, on the point of the sepals or in the septa of the ovary, the most typical position amongst the Asparagales.

虽然在大多数的物种中不存在，但花蜜可在唇瓣的距（片或花瓣、花萼或花冠上的、细小的、囊状、中空的附属结构。）中产出，在萼片的尖端或者在子房室之间的隔上，在天门冬目的植物里面所处位置最特别。

Sepals caducous after flowering, rarely one outer sepal persistent; keel with apical appendage flabelliform and lobed or laciniate flowers unknown in P. oligosperma

萼片早落花后，宿存的一外部萼片的很少；条裂的龙骨状具顶端附属物fmabelliform 和浅裂或(在oligosperma页花未知) 20

Plant monoecious. Male flowers sometimes solitary, sometimes in a thyrse 5-7 cm, 2-3 cm in diam.; pedicels 0.8-1.5 cm; sepals 2 large, 2 small; petals orange, obovate, 1-5 × as long as sepals; stamen fascicles stalk 2-3 mm, each fascicle with 50 anthers; anthers aggregated into a head, 2-celled, cells longitudinally dehiscent; pistillode columnar; stigma distinctly peltate, 4-lobed.

雌雄同株；雄花有时单生，有时在一聚伞圆锥花序内5-7厘米，直径2-3厘米；花梗0.8-1.5厘米；大的萼片2，小的2；花瓣橙，倒卵形，长为萼片的1-5 倍；雄蕊束簇柄2-3毫米，每束簇具50花药；花药聚生为头状花序，2室，室纵向开裂；退化雌蕊柱状；柱头清楚的盾形，4裂。

Petals bright yellow, oblong-oblanceolate, 1.2-1.8 cm × 4-8 mm, 1.5-1.8 × as long as sepals; laminar glands lines, sometimes interrupted distally; marginal glands absent; margin entire; apiculus absent.

花瓣亮黄，长圆形，1.2-1.8厘米×4-8毫米，长为萼片的1.5-1.8 倍；片状腺体线形，有时上部打断；边缘的腺体无；边缘全缘细尖缺席。

Historically, plants of this affinity with stamen number equal to sepal number were Ludwigia , and those with stamens twice as many as sepals were Jussiaea , but Raven and others demonstrated reticulate variation in this character, and treated the two groups as a single genus.

历史上，常具有与萼片数相同的雄蕊数的植株为 Ludwigia的，而雄蕊数为萼片的2倍的是Jussiaea的，但 Raven和其它人证明这一特征成网状式的变异，并且把这两个类群归入同一属内。

Male flowers: pedicel articulated at base; sepals 5, free, valvate, initially curved around stamens, later reflexed; petals and disk absent; stamens 5, free, inserted at bases of sepals; filaments short; anthers larger, thecae 2, parallel, introrse, dehiscence longitudinal; pistillode short and broad, peltate.

雄花 花梗有节在基部；萼片5，离生，镊合状，最初在雄蕊周围弯曲，后反折；花瓣和花盘无；雄蕊5，离生，着生在萼片的基部；花丝短；花药大，囊2，平行，内向，纵裂；退化雌蕊短和宽，盾形。

This subsection is related to subsect. Clematis, differing in its 6-sepalled flower andsepals with hairs 1.6-3 mm long.

本亚组与钝萼铁线莲亚组接近，但花具6枚萼片，萼片的毛较长(1.6-3 mm)而不同。

Petals bright yellow, sometimes red-veined, oblong-elliptic, 1-1.2 cm × ca. 5 mm, 2-3 × as long as sepals; laminar glands sparse, pale, lines to dots; margin sparsely black-glandular-ciliate.

花瓣明亮黄，有时红色，长圆状椭圆形，1-1.2厘米*长约5毫米，长为萼片的2-3 倍；片状腺体稀少，苍白，线形到小圆点；边缘疏生黑色具腺缘毛。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
