生叶状体的

Martensia was characterized by either single or multiple network-banded blades, procarps consisting of a four-celled carpogonial branch flanked on one side by a single lateral sterile group and on the other side by a group of cover cells, and cystocarp scattered over fertile blades.

此属的特点为藻体膜叶状且膜叶具有单或多层的网状结构，其雌性殖果孢枝特化具有侧边单一的不孕枝而另一边有一群覆盖细胞，果孢子囊散生在藻体各处。

Type Ⅰ consists of thallus with pores,and branches with center band.

Type Ⅰ具有叶状体，表面具有孔，叶状体上着生有具有中间加厚带的枝。

It was concluded that the photosynthesis and carbon budget of Ulva lactuca under aquatic state differed from that under aerial state, and such difference was associated with the conditions of ambient temperature and water statues of thalli.

认为石蒓在低潮气生状态下与在高潮水生状态下光合特性及净碳固定存在差异，但这种差异与环境温度及叶状体的水分状态有关。

Leaves apparently alternate, distichous; nanophylls present or absent, opposite to normal leaves; stipules 2; leaf blade 3-veined, one major lateral vein sometimes inserted above the base, or pinnately veined, base asymmetric, margin entire or serrate; cystoliths mostly present, linear or fusiform.

叶表面上互生，2列；微形叶宿存或无，对生于正常的叶；托叶2；叶片3脉，主要的一侧脉高于那些基部，或成羽状脉，基部不对称，边缘全缘或有锯齿；乳状体多数宿存，线或者纺锤形。

As it flows it takes the forms of sappy leaves or vines, making heaps of pulpy sprays a foot or more in depth, and resembling, as you look down on them, the laciniated, lobed, and imbricated thalluses of some lichens; or you are reminded of coral, of leopard's paws or birds' feet, of brains or lungs or bowels, and excrements of all kinds.

因为它流下来的时候，那状态颇像萌芽发叶，或藤蔓的蔓生，造成了许多软浆似的喷射，有时深达一英尺或一英尺以上，你望它们的时候，形态像一些苔藓的条裂的、有裂片的、叠盖的叶状体；或者，你会想到珊瑚，豹掌，或鸟爪，或人脑，或脏腑，或任何的分泌。

Leaves alternate, petiolate; stipules caducous, intrapetiolar, connate, often broad, foliaceous; leaf blade 3-veined, margin dentate or lobed; cystoliths punctiform.

叶互生，具叶柄；托叶早落，叶柄内，合生，经常宽，叶状；3脉的叶片，浅裂的边缘具牙齿或；钟乳体点状。

Cauline leaves petiolate; sepals membranous only at margin, remaining until young fruit develops; petals caducous; style minutely papillate, cylindric; stem trichomes crisped simple and forked, or malpighiaceous; raceme elongated considerably in fruit.

茎生叶具叶柄；萼片膜质只在边缘，保持直到幼果发育；花瓣早落；花柱微小乳突，圆筒状；皱波状的茎毛状体单纯和分叉，或者；总状花序在果期相当大地拉长。

Cauline leaves pinnatisect or pinnatifid, broader; stems pilose with trichomes to 1 mm

茎生叶羽状全裂或者羽状半裂，宽；茎具柔毛的具毛状体到1毫米 2 C。

At least basal leaves dentate, serrate, or pinnatifid; median filaments free; stems glabrous or with straight trichomes.

至少基生叶具牙齿，使成锯齿波，或羽状半裂；中间的花丝离生；茎无毛的或具直的毛状体。

Sometimes armed with stinging hairs; epidermal cells of leaves, sometimes stems, perianths mostly with prominent cystoliths punctiform to linear; Leaves alternate or opposite, stipules present, rarely absent; leaf blade simple. Inflorescences cymose, paniculate, racemose, spicate, or cluster-capitate, usually formed from glomerules, sometimes crowded on common enlarged cuplike or discoid receptacle, rarely reduced into a single flower. Flowers unisexual, rarely bisexual in partial flowers; actinomorphic, very small,(1-)4- or 5-merous, rarely perianth absent in female flowers.

有时具有蛰毛的刺；叶的表皮细胞，有时茎和花被的表皮细胞大部分有显著的点状或线形的乳状体；叶互生或者对生，托叶有，很少无；单叶花序聚伞状，圆锥状，总状，穗状，或者丛生头状花序，花单性，部分花两性；辐射对称，小，(1-)4-或者5瓣，很少在雌花内无花被。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
