. The elements of botany for beginners and for schools. Botany. SECTION 8.] MODIFICATIONS OF THE TYPE. 91. Tabular; wlieu prolonged into a tube, with, little or no spreading at the border, as iu the corolla of the Trumpet Honeysuckle, the calyx of Stra- luoniuni (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, an- swering to petiole. This is called its , iu Latiu Unguis. Unguicu- late petals are universal and strongly marked in the Pink tribe, as in Soapwort (Fig. 248). 262. Such petals, and various others, may have 259 260 an outgrowth of the in- ner face into an appendage or fringe, as in Soapwort, and iu Silene (Fig. 259), where it is at the junction of claw and blade. This is called a Crown, or Corona. In Passion- flowers (Fig. 260) the crown consists of numerous threads on the base of each petal. 263. Irregular Flowers may be polypetalous, or nearly so, as in the papilionaceous corolla; but most of them are irregular through coales- cence, which often much disguises the numerical symmetry also. As affecting the corolla the following forms have received particular names: 264, Papilionaceous Corolla, Fig. 261, 262. This is polypetalous, except that two of the petals cohere, usually but slightly. It belongs only to the Leguminous or Pulse family. The name means butterfly-like; but the likeness is hardly obvious. The names of the five petals of the papilionaceojis corolla are curiously incongruous.
