萼

The cypsela of 6 genera (32 species) from eastern Qinghai-Tibetan Plateau were collected. The length, width and length/width of the cypsela were computed, then the relativity about the length, width, length/width of the cypsela and altitude were analyzed.

采集青藏高原东缘6属32种菊科植物的连萼瘦果，测算其长度、宽度和长／宽3项指标，并对上述指标与植物分布海拔高度的相关性进行了分析。

Sepals [2 or 3 or]4 or 5, decussate or imbricate, free .

萼片 [2或3或者 ]4或5，交互对生或成鳞状，离生。

Bracts linear; lower calyx teeth indistinct; lobes of upper lip of corolla divaricate almost at right angles

苞片线形更低的萼齿不清楚；极叉开的花冠的上唇的裂片几乎在直角 2 Lavandula latifolia 宽叶薰衣草

Drupe obovoid-globose, with 2 or 3 one-seeded stones, base with remnants of persistent calyx tube.

核果倒卵球形球状，具2或3 一种子的核，基部具宿存的萼筒的残余。

Trees 10–25 m tall; sepals nearly as long as hypanthium; drupe 1.2–2.5 cm.

乔木10-25米高；萼片近等长托杯；核果的1.2-2.5 厘米 12

Drupe 1-loculed, 1-seeded, with persistent calyx tube at base.

核果1室，1种子，具宿存的萼筒在基部。

Leaflet apex emarginate to obcordate, not mucronate and apiculate; outer 3 sepals of male flowers ca.

小叶先端微缺到倒心形，不短尖和具细尖；外部3雄花的萼片约1.4厘米 12 S。

Petals obovate-cucullate, ca. as long as sepals, base shortly clawed, apex rounded or emarginate.

花瓣倒卵形兜状，与萼片近等长，基部短爪，先端圆形或微缺。

Petals white, longer than sepals; blade obovate or broadly so, apex rounded or emarginate; claw obscure.

花瓣白色，长于萼片；宽如此的叶片倒卵形的或，先端圆形或微缺；瓣爪不明显。

Petals yellow, spreading; blade obovate, apex obtuse or emarginate; claw subequaling sepals.

花瓣黄色，平展；叶片倒卵形，先端钝的或微缺；近相等的瓣爪萼片。

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。
