Nutlets 4, semiglobose-tetrahedral or subulate trigonous-tetrahedral, shiny, glabrous or pubescent, rarely tuberculate, adaxial 3 surfaces subequal in size or bottom smaller than 2 lateral surfaces, longitudinal vein at juncture of 2 lateral surfaces, sessile or with a short carpophore from corner of 3 adaxial surfaces, abaxial surfaces flattened or convex, acute or obtuse ribbed, rarely narrow winged; attachment scar at bottom of carpophore or at corner of 3 adaxial surfaces when sessile.

Sepals 5, imbricate, apex obtuse to caudate.

萼片5，覆瓦状，先端钝到尾尖。

Fruit oblong, terete, glabrous; ribs 5, acute or round-obtuse; vittae 1 in each furrow, 2 on commissure.

果长圆形，圆柱状，无毛；棱5，锐尖的或圆形钝；油管每棱槽1，在合生面上2。

Leaf blade crenate; obtuse or auriculate at base.

叶片具圆齿；钝的或耳形在基部。

Margin of leaf blade crenate; petals triangular or triangular-ovate, apex obtuse, rarely acute.

When to take four samples in one tree, commonly the samples are taken in "cross" relation, but the analysis shows it is not the best choice. The more the samples are taken at obtuse angle with each other, the better the representation of the samples.

在两个或者3个方位采样时，方位之间呈钝角关系时，其代表性最好。4个方位采样时，一般使用的"十字交叉法"并不是最好的选择，建议采样的方位之间尽可能多的成钝角关系。

To address the issue, we analyze the correlation and similarity of the different radii sequence and the different combination sequence with the full- ring-sample sequences, based on 642 δ13C data of cellulose fixed in tree-ring at 8 different radii of two Cryptomeria fortunei tree disks from Mt. Tianmu, a subtropical mountain of China. It suggests that 2 to 4 radii mixture sample is the better and more efficient choice for the tree-ring δ13C analysis. It had better to take samples at obtuse angle with each other when to take samples at two or three radii.

研究利用来自天目山的两个柳杉树盘的多方位的和整轮的碳同位素测试数据（共计642个），通过不同方位和不同方位组合的平均碳同位素序列与整轮碳同位素序列的关系的多角度的考查、分析发现，并不是采样的方位数越多越好，选择2~4个方位采样合并分析树轮稳定碳同位素，既经济方便又能比较好的反映一棵树的δ13C变化过程与趋势。

Petals white or greenish white; flowers at least 15 mm, middle outer sepal and apical appendage of keel cucullate; stems with dense, raised leaf scars and lenticels; leaf blade slightly fleshy, elliptic-obovate to spatulate, 5-6 mm wide, apex obtuse.

花瓣白色或带绿色白色；花至少15毫米，中间外部萼片和龙骨瓣顶端附属物兜状；茎具紧密的，提高叶痕和皮孔；叶片稍肉质，椭圆状倒卵形的到匙形，5-6毫米宽，先端钝。 12 P。 dunniana 贵州远志

Connectors are lines that can be anchored to particular places, called glue points , on the graphic object.

Another way of putting it, too many agents have a say in each other's work, and bureaucratic rigor mortis sets in.
