palous calyx, such as

_Wheel-shaped_, or _Rotate_; when spreading out at once, without a tube
or with a very short one, something in the shape of a wheel or of its
diverging spokes, Fig. 252, 253.

_Salver-shaped_, or _Salver-form_; when a flat-spreading border is
raised on a narrow tube, from which it diverges at right angles, like
the salver represented in old pictures, with a slender handle beneath,
Fig. 249-251, 255.

[Illustration: Fig. 248. Polypetalous corolla of Soapwort, of five
petals with long claws or stalk-like bases.]

[Illustration: Fig. 249. Flower of Standing Cypress (Gilia
coronopifolia); gamopetalous: the tube answering to the long claws in
248, except that they are coalescent: the limb or border (the spreading
part above) is _five-parted_, that is, the petals not there united
except at very base.]

[Illustration: Fig. 250. Flower of Cypress-vine (Ipomoea Quamoclit);
like preceding, but limb _five-lobed_.]

[Illustration: Fig. 251. Flower of Ipomoea coccinea; limb almost
_entire_.]

[Illustration: Fig. 252. Wheel-shaped or rotate and five-parted corolla
of Bittersweet, Solanum Dulcamara. 253. Wheel-shaped and five-lobed
corolla of Potato.]

_Bell-shaped_, or _Campanulate_; where a short and broad tube widens
upward, in the shape of a bell, as in Fig. 254.

[Illustration: Fig. 254. Flower of a Campanula or Harebell, with a
campanulate or bell-shaped corolla; 255, of a Phlox, with salver-shaped
corolla; 256, of Dead Nettle (Lamium), with labiate _ringent_ (or
gaping) corolla; 257, of Snapdragon, with labiate _personate_ corolla;
258, of Toad-Flax, with a similar corolla spurred at the base.]

_Funnel-shaped_, or _Funnelform_; gradually spreading at the summit of a
tube which is narrow below, in the shape of a funnel or tunnel, as in
the corolla of the common Morning Glory (Fig. 247) and of the Stramonium
(Fig. 246).

_Tubular_; when prolonged into a tube, with little or no spreading at
the border, as in the corolla of the Trumpet Honeysuckle, the calyx of
Stramonium (Fig. 246), etc.

261. Although sepals and petals are usually all blade or lamina (123),
like a sessile leaf, yet they may have a contracted and stalk-like base,
answering to petiole. This is called its CLAW, in Latin _Unguis_.
_Unguiculate_ petals are universal and strongly marked in the Pink
tribe, as in Soapwort (Fig. 248).

two-parted crown.]
