  • Bluets (Houstonia caerulea)

    KONICA MINOLTA DIGITAL CAMERA

    KONICA MINOLTA DIGITAL CAMERAAlso known as Quaker Ladies, these tiny blue flowers form tidy clumps in shaded lawns and roadsides. Small as the delightful four-petaled flowers are, they rise from a plant that seems tiny out of all proportion to the flowers. These were blooming in late May (a little late this year) in Frick Park.

    Gray describes the genus and the species:

    HOUSTÔNIA L. Calyx 4-lobed, persistent; the lobes in fruit distant. Corolla usually much longer than the calyx-lobes, the lobes valvate in the bud. Anthers linear or oblong. Style 1; stigmas 2. Ovary 2-celled. Pod top-shaped, globular, or didymous, thin, its summit or upper half free from and projecting beyond the tube of the calyx, loculicidal across the top. Seeds 4-20 in each cell, pitted. — Small herbs, with short entire stipules connecting the petioles or narrowed bases of the leaves, and cymose or solitary and peduncled flowers; these dimorphous, in some individuals with exserted anthers and short included style; in others the anthers included and the style long, the stigmas therefore protruding. (Named for Dr. William Houston, an English botanist, who collected in tropical America.)

    Small and delicate, vernal-flowering; peduncles 1-flowered; corolla salverform; upper half of the broad and someirhat 2-lobed pod free; seeds globular, with a very deep round cavity occupyiny the inner face.

    Perennial by delicate filiform creeping rootstocks or creeping stems; peduncles filiform, 2-5 cm. long.

    H. caerulea L. (BLUETS, INNOCENCE.) Glabrous; stems erect, slender, sparingly branched from the base, 0.5-2 dm. high; lrares oblong-spatulate,6-9 mm. long; peduncle filiform, erect; corolla light blue, pale lilac or nearly white, with a yellowish eye, the straight slender long-exserted tube much longer than its lobes or than those of the calyx. — Moist and grassy places, N. S. to Ga., w. to Ont., Wise, and Ala.; producing from early spring to midsummer its delicate little flowers.

  • Golden Ragwort (Senecio aureus)

    KONICA MINOLTA DIGITAL CAMERA

    Now Packera aurea, but the old name is so much better known that most Internet searchers are not likely to find an article on “Packera.”

    Golden Ragworts are attractive flowers, a bit like a yellow aster, that bloom in the middle spring, just after the tulips in your garden. The heart-shaped basal leaves and the pinnately lobed (rather fern-like) stem leaves are distinctive. They like a somewhat shady location; these were blooming in late May (a little later than usual this year) near a stream in Scott Township.

    A peculiar property of Golden Ragworts is their resistance to the autofocus systems on most digital cameras. If one does not resort to manual focus, it takes a great many pictures to get a few that are decently in focus. If you are a graduate student in evolutionary biology, here is a thesis topic for you.

    Gray (with help from J. M. Greenman) describes the genus and the species:

    SENECIO [Tourn.] L. GROUNDSEL. RAGWORT. SQUAW-WEED. Revised By J. M. Greenman. Heads many-flowered; rays pistillate or none; involucre cylindrical to bell-shaped, simple or with a few bractlets at the base, the bracts erect-connivent. Receptacle flat, naked. Pappus of numerous very soft and capillary bristles.— Ours herbs, with alternate leaves and solitary or eorymbed heads. Flowers chiefly yellow. (Name from senex, an old man, alluding to the hoariness of many species, or to the white hairs of the pappus.)

    S. aureus L. (GOLDEN R. ) Stems erect from rather slender rootstocks, 3-8 dm. high, at first often lightly floccose-tomentose, soon glabrate; lower leaves long-petioled, ovate-rotund to slightly oblong, 1.5-8 cm. long, two thirds as broad, crenate-dentate; stem-leaves lyrate to laciniate-pinnatifid; the uppermost sessile, amplexicaul, often bract-like; inflorescence cymose-corymbose; heads radiate; rays yellow; achenes glabrous. — In wet meadows, moist thickets, and swamps, Nfd., s. to Va., w. to Wisc., Mo., and Ark. May-Aug.

  • Foamflower (Tiarella cordifolia)

    Obviously this is one of our favorite flowers, since this is its third time being featured here. (More pictures are here and here.)

    As we see here, some forms of this species grow leaves with deep red markings along the veins, and those forms have been developed into cultivated varieties with even more pronounced red markings. All the plants in this hollow in Schenley Park had the red markings on their leaves. They were blooming in early May, a little later than usual this year.

    Gray describes the genus and the species:

    TIARELLA L. FALSE MITERWORT. Calyx bell-shaped, 5-parted. Petals 5, with claws. Stamens long and slender. Styles 2. Capsule membranaceous, 2-valved; the valves unequal. Seeds few, at the base of each parietal placenta, globular, smooth. Perennials; flowers white. (Name a diminutive from tiara, a tiara, or turban, from the form of the pistil, which is like that of Mitella, to which the name of Miterwort properly belongs.)

    T. cordifolia L. Leaves from the rootstock or summer runners, heart-shaped, sharply lobed and toothed, sparsely hairy above, downy beneath; stem (1-4 dm. high) leafless or rarely with 1 or 2 leaves; raceme simple; petals oblong, often subserrate. Rich rocky woods, N. S. and N. B. to Minn., Ind., and southw. in the mts. Apr.-June.

  • Bloody Butcher (Trillium recurvatum)

    We must admit that we have no idea what this plant is doing here. We had first identified this as Trillium sessile, but Mr. Scott Namestnik pointed out in a comment that this plant clearly seems to be T. recurvatum. But how did it get here in Bird Park, Mount Lebanon, merrily blooming in mid-May as if it were perfectly at home? Neither Gray nor the USDA PLANTS database places any wild populations of Trillium recurvatum anywhere in the Pittsburgh metropolitan area, or even within two hundred miles. It is a prairie-state plant, almost unknown in Ohio, and not common till Indiana, although (oddly) there is apparently an isolated wild population way over in Lancaster County, Pennsylvania. Is someone attempting to populate Bird Park with unusual wildflowers? Or have we discovered something previously unknown in the botanical literature—another isolated wild population, like the one in Lancaster County?

    Gray describes the genus and the species:

    TRÍLLIUM L. WAKE ROBIN. BIRTHROOT. Sepals 3, lanceolate, spreading, herbaceous, persistent. Petals 3, larger, withering in age. Stamens б; anthers linear, on short filaments, adnate. Styles awl-shaped or slender, spreading or recurved above, persistent, etig matic down the inner side. Seeds ovate, horizontal, several in each cell. — Low perennial herbs, with a stout and simple stem rising from a short and praemorse tuber-like rootstock, bearing at the summit a whorl of 3 ample, commonly broadly ovate, more or less ribbed but netted-veined leaves, and a terminal large flower; in spring. (Name from tres, three; all the parts being in threes.) — Monstrosities are not rare with the calyx and sometimes petals changed to leaves, or the parts of the flower increased in number.

    Ovary and fruit 6-angled and more or less winged.

    Flower sessile; leaves usually mottled.

    T. recurvàtum Beck. Leaves contracted at the base into a petiole, ovate, oblong, or obovate; sepals reflexed; petals pointed, the base narrowed into a claw, oblong-lanceolate to -ovate, dark purple; fruit ovoid, strongly winged above, 1.8 cm. long. — Rich woods, O. to Minn., Ark., “Miss.,” and Tenn.

  • Lily of the Valley (Convallaria majalis)

    KONICA MINOLTA DIGITAL CAMERALily of the Valley, a favorite ornamental ground cover for shady spots, is a frequent escape from gardens; it may sometimes mark old homesites, as a patch can persist indefinitely. It comes from the Old World, but it is also apparently native (there is some debate) to the Appalachians; if so, however, its native range is well to the south of our area. When we see Lily of the Valley growing in the wild, we may regard it as a guest rather than a resident. These plants were blooming in the middle of May deep in the woods in Bird Park, Mount Lebanon.

    Gray describes the genus and the species:

    CONVALLÀRIA L. LILY OF THE VALLEY. Perianth bell-shaped, white, with 6 short recurved lobes. Stamens 6, included, inserted on the base of the perianth; anthers introrse. Ovary 3-celled, tapering into a stout style; stigma triangular. Ovules 4-6 in each cell. Berry few-seeded, red. — Perennial herb, glabrous, stemless, with slender running root- stocks, 2 or 3 oblong leaves, and an angled scape bearing a one-sided raceme of sweet-scented nodding flowers. (From Lilium convallium, the popular name.)

    С majàlis L. — High mountains, Va. to S. С. — Apparently identical with the European Lily of the Valley of the gardens which occurs as an occasional escape from cultivation elsewhere within our limits.
