萼片

Sepals lanceolate or ovate-orbicular, sometimes shallowly boat-shaped, inner 2 often connate at base.

萼片披针形或卵形圆形，有时舟状，内部2通常在基部合生。

Sepals free, shallowly to strongly boat-shaped.

萼片离生，浅对强烈舟状。

Culm sheaths brown-red when fresh, with sparse or rather dense small spots, distal margins dark purple

没有腺毛的花梗和萼片；种子肾形三角形，具凹槽 56

Flowers tubular ,campanulate or almost spreading ,bisexual (stamens and pistil in one flower )or unisexual (female and male flowers on the same plant), up to 4cm across. Tepals 4-6, white, cream-yellow, red-purple,or violet-blue .

花朵呈管状，铃状，或者几乎平展，雌雄同体或雌雄异体，茎达4cm 。4-6个萼片，白色，奶黄色，紫红色或紫罗兰色。

After 20 days of culture, the floral bud was still undifferentiated and it would differentiate in 30 days. Floral anlage was formed after 40 days of culture.

处理20d时花芽仍未分化，30d时将分化，40d左右逐渐分化出花原基，50～80d可观察到萼片原基、花瓣原基、合蕊柱。

Sepals completely united in bud, splitting into 2 at anthesis; stamens free or all basally united; fasciclodes absent; ovary 2-loculed, each locule 2-ovuled; leaf venation densely and prominently reticulate with translucent gland dots in areoles.

萼片完全合生在芽中，分成2在花期；雄蕊离生或全部基部合生；下位腺体缺席；子房2室，每的子房室2胚珠；在小窠里的浓密和显著的叶脉网状的具半透明的腺体小圆点。 7 Mammea 格脉树属

Sepals smaller, auricles less than 2 mm; stipules smaller

更小的萼片，叶耳不到2毫米；托叶小 45

Sepals oblong or oblong-ovate, base obtuse or shallowly dentate, apex obtuse, basal auricles 2-3 mm.

萼片长圆形或长圆状卵形，基部钝或具浅牙齿，先端钝的，基部耳2-3毫米。

Calyx cupular; sepals 5, imbricate, stellate or tomentose.

花萼杯状萼片5，覆瓦状，或被绒毛。

Cymes usually with numerous flowers; petals shorter than or subequaling sepals, sometimes very small or absent.

聚伞花序通常具许多花；花瓣短于或近等长于萼片，有时很小或无。

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.
