1, CUSCUTA [Tourn.] L. Sp. Pl. 124. 1753.

Characters of the family. The filiform twining stems are parasitic on herbs and shrubs
by numerous minute suckers. The seeds germinate in the soil and the plantlet attaches itself
to its host, its root and lower portion soon perishing. The subsequent nutrition of the
parasite is apparently wholly through its suckers. [Name from the Arabic.]

occur in the southern and western parts of North America. Known as Dodder, or Strangle-weed.

21. STACHYS [Tourn | L2 Sp: Pl 580, tazse:

Annual or perennial glabrous pubescent or hirsute herbs, with small or rather large
purple yellow red or white flowers, loosely verticillate-clustered in terminal dense or inter-
rupted spikes, or also in the upper axils. Calyx mostly campanulate, 5-10-nerved, 5-toothed,
the teeth nearly equal in our species. Corolla purple in our species, its tube narrow, not
exceeding the calyx, the limb strongly 2-lipped; upper lip erect, concave, entire or emarginate;
lower lip spreading, 3-cleft, the middle lobe broader than the lateral ones, sometimes 2-lobed. ,
Stamens 4, didynamous, ascending under the upper lip of the corolla, the anterior pair the
longer, sometimes deflexed or twisted after anthesis; anthers contiguous in pairs, 2-celled,
the sacs mostly divergent. Ovary deeply 4-lobed; style 2-cleft at the summit into subulate
lobes. Nutlets ovoid or oblong. [Greek, a spike, from the spicate inflorescence. ]

Ed. 4. 1754. Sy

Herbs, some exotic species shrubby, with alternate entire
dentate or lobed leaves, or the lower and those of sterile
shoots opposite or verticillate, and yellow white blue purple
or variegated flowers, in terminal bracted racemes or spikes.
Calyx 5-parted, the segments imbricated. Corolla irregu-
lar, spurred at the base, or the spur rarely obsolete, 2-lipped,
the upper lip erect, 2-lobed, covering the lower in the bud,
the lower spreading, 3-lobed, its base produced into a palate
often nearly closing the throat. Stamens 4, didynamous,

weeds, some shrubby, with alternate leaves, or the lower opposite, and small heads

Pistillate flowers with no corolla, or this reduced to a short tube or ring; calyx
adnate to the 1-celled ovary, its limb none, or a mere border; style 2-cleft. Stami-
nate flowers with a funnelform tubular or obconic 4—5-lobed corolla; stamens
mostly 5, separate, or their anthers merely connivent, not truly syngenesious, with
short inflexed appendages; ovary rudimentary; summit of the style often hairy

THISTLE FAMILY,

Herbs, rarely shrubs (some tropical forms trees), with watery or resinous
(rarely milky) sap, and opposite alternate or basal exstipulate leaves. Flowers
perfect, pistillate, or neutral, or sometimes monoecious or dioecious, borne cn a
common receptacle, forming heads, subtended by an involucre of few to many bracts
arranged in one or more series. Receptacle naked, or with chaffy scales subtend-
ing the flowers, smooth, or variously pitted or honeycombed. Calyx-tube com-
pletely adnate to the ovary, the limb (pappus) of bristles, awns, teeth, scales, or
crown-like, or cup-like, or wanting. Corolla tubular, usually 5-lobed or 5-cleft, the
lobes valvate, or that of the marginal flowers of the head expanded into a ligule
(ray ) ; when the ray-flowers are absent the head is said to_be discoid; when present,
radiate ; the tubular flowers form the disk. Stamens usually 5, borne on the corolla
and alternate with its lobes, their anthers united into a tube (syngenesious ), often
appendaged at the apex, sometimes sagittate or tailed at the base; pollen-grains
globose, often rough or prickly. Ovary 1-celled; ovule 1, anatropous; style of
fertile flowers 2-cleft, its branches variously appendaged, or unappendaged ; stigmas
marginal; style of sterile flowers commonly undivided. Fruit an achene. Seed
erect ; endosperm none; embryo straight ; hypocotyl inferior.
