88 ILLUSTRATIONS OF INDIAN BOTANY. 



or several series. Corolla monopetalous, inserted on the top of the calyx tube, nenrumphi-' 



petalous, that is, the petals are furnished on the margins with nerves, whence there usually 



appear only 5 nerves in the tube (two and two united), extending from the base to the divisions, 



and ten in the limb, one on each margin of each lobe ; to these are sometimes added, but 



very rarely visible, accessory nerves occupying the middle of the petals. The length of the 



tube from the base to the point of apparent attachment of the filaments is various. The throat 



is often dilated from the insertion of the filaments to the lobes : the lobes are usually S, more 



rarely 4, 3, or 2, valvate in estivation ; sometimes they are all equal, sometimes more or less 



unequal or irregular, or palmated, or two-lipped (the outer lip formed by the cohesion of 



3 lobes, and the mner of 2 ; or the outer of 4 and the inner of 1, sometimes divided by 



a smgle fissure on the mterior side, and then all are united into a single, flat, 5-toothed, 



strap-hke petal. Stanaens 5, rarely 4, wanting, or rudimentary, in female or sterile flowers : 



filaments alternate with the lobes of the corolla and therefore congruent with the nerves of 



the tube ; attached to the tube of the corolla and free above ; either altogether distinct or 



united into a tube (monadelphous), jointed near the apex, the upper joint antheriferous and 



occupying the place of a connective. Anthers ereet, united into a tube round the style, 



(Syngenesia or SynanthereaJ, Imear, 2-celled, opening within by a longitudinal slit, 4-valved ; 



valves bent outwards (extroflexis) terminating in an appendix or winl varying in different 



plants in the size and shape, often differing in consistence from the polleniferous portion : the
