Dark glands present on at least sepals and/or anthers or leaves; stem internodes 2-lined or terete; stamens usually apparently 3(or 4)-fascicled

在至少萼片和花药或叶上的深色的腺体宿存；茎节间的2线棱或圆柱状；雄蕊通常表面上3(或4)簇生 43

Sepals elliptic to oblong or foliose; leaves lanceolate to ovate-lanceolate,± triangular, with venation (secondary and sometimes tertiary) conspicuous

萼片椭圆形到长圆形或叶状；叶披针形到卵状披针形，多少三角形，具脉序次要和有时第三明显 22

Sepals free, boat-shaped, galeate at apex.

萼片离生，舟状，盔状的在先端。

Female flowers 1-3 at base of inflorescence, sometimes absent; pedicel distinct; sepals [2 or]3, irregularly triangular, fused at base, glandless; petals and disk absent; ovary [2 or]3-locular, smooth, usually glabrous; style present; stigmas [2 or]3, undivided, glandless.

在花序的基部的雌花1-3，有时无；花梗清楚；萼片 [2或者 ]3，不规则三角形，在基部愈合，无腺体；花瓣和花盘无；子房 [2或者 ]3室，平滑，通常无毛；花柱宿存柱头 [2或者 ]3，不裂，。

Leaves often glaucous abaxially; flowers 1.5–2 cm in diam.; sepals 5–7.5 mm, margin entire.

叶通常有白霜背面；直径的花1.5-2厘米；萼片5-7.5毫米，边缘全缘。

The results indicated that compared with short photoperiod, under long photoperiod, plant height, caudex, leaf and leaf number increased, florescence delayed; The phase from the calyx differentiation stage to gynoecia differentiation stage lasted 3~4 days.

采用10h和16h两种光照条件对紫苏进行处理，观测光周期对紫苏生长发育的影响，结果表明：与短日照条件下的相比，长日照条件下生长的供试材料叶片数增加，叶片增大，茎增粗，植株增高，开花延迟；花芽分化从萼片原基形成开始，到雌蕊形成为止，持续3~4d。

Fruit terete, torulose; sepals 3.5-5.5(-7) mm; petals 6-8(-10)× 1-1.5 mm; filaments 3-5(-6) mm; anthers 1-1.5 mm; middle leaves often lobed or hastate basally

果圆柱状，近念珠状；萼片3.5-5.5(-7)毫米；花瓣 6-8(-10)* 1-1.5 毫米；花丝3-5(-6)毫米；花药1-1.5毫米；基部的中部叶通常浅裂的或戟形 9 S。

Fruit subquadrangular, not torulose; sepals 7-9 mm; petals 12-16 × 2.5-3.5 mm; filaments 6-10 mm; anthers 2-3 mm; middle leaves not lobed or hastate basally

果近四棱，不近念珠状；萼片7-9毫米；花瓣 12-16 * 2.5-3.5 毫米；花丝6-10毫米；花药2-3毫米；基部的中部叶不裂或戟形 8 S。

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。
