In the eases above cited, it is commonly taught that the receptacle ia lo- cated at the base of the ovary, and that all the organs thence arisuig are adherent to its sides. Another doctrine is also taught, viz., that the receptacle itself may be elevated and become perigynous or epigynoua, or, in other words, the ovary may be imbedded in the foot-stalk. That it is so in the rose (289) we can hardly doubt The so-called calyx-tube of the cherry, peach, is certainly an analogous structure, more expanded, and so is the more contracted " calyx tube" of the apple, pome- granate. The analogy extends throughout the Rosewoi'ts, and perhaps still further. 468. Calyx half-superior. Calyx superior or free, ovary inferior or free, are all phrases of the same import as calyx hypogynous. Be- tween the two conditions, calyx superior and calyx inferior, there are numerous gradations, of which one only is defined, to wit, calyx half- superior, as exemplified in the mock orange (and 310.) â 469. Special forms of the perianth, whether calyx, corolla, or both, have been named and described. We may arrange them thus:â PoLTPETALOUS, regularâCruciform, rosaceous, caryophyllaceous, liliaceous. Ir- regularâpapilionaceous, orchidaceous. MON'OPBTALOOs, regular mostlyârotate, cup-shaped, campanulate, urceolate, ftm- nel-form, salver-form, tubular. Irregularâligulate, labiate. 470. Cruciform {crux, a cross) or cross-shaped, implies that four long clawed, spreading petals stand at right angles to each other, as in the flowers of the mustard family (Cruciferse) in general. 471.
