第10章 FROM BLUE TO PURPLE FLOWERS(8)

The SHARP-LOBED LIVER-LEAF (Hepatica acuta) differs chiefly from the preceding in having the ends of the lobes of its leaves and the tips of the three leaflets that form its involucre quite sharply pointed.Its range, while perhaps not actually more westerly, appears so, since it is rare in the East, where its cousin is so abundant; and common in the West, where the round-lobed liver-leaf is scarce.It blooms in March and April.

Professor Halsted has noted that this species bears staminate flowers on one plant and pistillate flowers on another; whereas the Hepatica Hepatica usually bears flowers of both sexes above the same root.The blossoms, which close at night to keep warm, and open in the morning, remain on the beautiful plant for a long time to accommodate the bees and flies that, in this case, are essential to the perpetuation of the species.

PURPLE VIRGIN'S BOWER

(Atragene Americana) Crowfoot family Flowers - Showy, purplish blue, about 3 in.across; 4 sepals, broadly expanded, thin, translucent, strongly veined, very large, simulating petals; petals small, spoon-shaped; stamens very numerous ; styles long, persistent, plumed throughout.Stem:

Trailing or partly climbing with the help of leafstalks and leaflets.Leaves: Opposite, compounded of 3 egg-shaped, pointed leaflets on slender petioles.

Preferred Habitat - - Rocky woodlands.

Flowering Season - May-June.

Distribution - Hudson Bay westward, south to Minnesota and Virginia.

The day on which one finds this rare and beautiful flower in some rocky ravine high among the hills or mountains becomes memorable to the budding botanist.At an elevation of three thousand feet in the Catskills it trails its way over the rocks, fallen trees, and undergrowth of the forest, suggesting some of the handsome Japanese species introduced by Sieboldt and Fortune to Occidental gardens.No one who sees this broadly expanded blossom could confuse it either with the thick and bell-shaped purple LEATHER-FLOWER (C.Viorna), so exquisitely feathery in fruit, that grows in rich, moist soil from Pennsylvania southward and westward; or with the far more graceful and deliciously fragrant purple MARSH CLEMATIS (C.crispa) of our Southern States.The latter, though bell-shaped also, has thin, recurved sepals, and its persistent styles are silky, not feathery at seed-time.

ORPINE; LIVE-FOREVER; MIDSUMMER-MEN; LIVE-LONG; PUDDING-BAGPLANT; GARDEN STONECROP; WITCHES' MONEY

(Sedum Telephium) Orpine family Flowers - Dull purplish, very pale or bright reddish purple in close, round, terminal clusters, each flower 1/3 in.or less across, 5-parted, the petals twice as long as the sepals; 10stamens, alternate ones attached to petals; pistils 4 or 5.Stem:

2 ft.high or less, erect, simple, in tufts, very smooth, pale green, juicy, leafy.Leaves: Alternate, oval, slightly scalloped, thick, fleshy, smooth, juicy, pale gray green, with stout midrib, seated on stalk.

Preferred Habitat - Fields, waysides, rocky soil, originally escaped from gardens.

Flowering Season - June- September.

Distribution - Quebec westward, south to Michigan and Maryland.

Children know the live-forever, not so well by the variable flower - for it is a niggardly bloomer - as by the thick leaf that they delight to hold in the mouth until, having loosened the membrane, they are able to inflate it like a paper bag.Sometimes dull, sometimes bright, the flower clusters never fail to attract many insects to their feast, which is accessible even to those of short tongues.Each blossom is perfect in itself, i.e., it contains both stamens and pistils; but to guard against self-fertilization it ripens its anthers and sheds its pollen on the insects that carry it away to older flowers before its own stigmas mature and become susceptible to imported pollen.After the seed-cases take on color, they might be mistaken for blossoms.

As if the plant did not already possess enough popular names, it needs must share with the European goldenrod and our common mullein the title of Aaron's rod.Sedere, to sit, the root of the generic name, applies with rare appropriateness to this entire group that we usually find seated on garden walls, rocks, or, in Europe, even on the roofs of old buildings.Rooting freely from the joints, our plant forms thrifty tufts where there is little apparent nourishment; yet its endurance through prolonged drought is remarkable.Long after the farmer's scythe, sweeping over the roadside, has laid it low, it thrives on the juices stored up in fleshy leaves and stem until it proves its title to the most lusty of all folk names.

PURPLE or WATER AVENS

(Geum rivale) Rose family Flowers - Purple, with some orange chrome, 1 in.broad or less, terminal, solitary, nodding; calyx 5-lobed, purplish, spreading;5 petals, abruptly narrowed into claws, forming a cup-shaped corolla; stamens and pistils of indefinite number; the styles, jointed and bent in middle, persistent, feathery below.Stem: 1to 2 ft.high, erect, simple or nearly so, hairy, from thickish rootstock.Leaves: Chiefly from root, on footstems; lower leaves irregularly parted; the side segments usually few and small; the 1 to 3 terminal segments sharply, irregularly lobed; the few distant stem leaves 3-foliate or simple, mostly seated on stem.

Fruit: A dry, hairy head stalked in calyx.

Preferred Habitat - Swamps and low, wet ground.

Flowering Season - May-July.

Distribution - Newfoundland far westward, south to Colorado, eastward to Missouri and Pennsylvania, also northern parts of Old World.

Mischievous bumblebees, thrusting their long tongues between the sepals and petals of these unopened flowers, steal nectar without conferring any favor in return.Later, when they behave properly and put their heads inside to feast at the disk on which the stamens are inserted, they dutifully carry pollen from old flowers to the early maturing stigmas of younger ones.

  • 军营童话

    军营童话

    和平时期创作军事题材类小说,对没有经历过战争洗礼的军旅作家来说具有挑战性。如何另辟蹊径,既紧扣时代主题,又体现军营特色,是创作军事题材类小说需要共同面对的问题。作者从女军人特有的视角,避开英雄、远离圣贤,以平静而细腻的笔调描绘出了主人公对亲人的孝、对朋友的诚和对事业的忠,突显了新世纪新阶段军人的价值取向、伦理道德和对人生的思考……《军营童话》没有提出国家和民族生死存亡的大是大非问题,但透过“平淡”的军营生活能使人们感受到打赢未来战争的坚强信心;她没有耗费过多笔墨描述精彩刺激的战争场面,但紧贴新时期军队历史使命勾勒出了热火朝天的军营气象;她没有煊染更多生离死别的感人场面,但细腻的亲情、友情和爱情同样能拨人心弦。
