“ Engelmann makes use of the word frondescence in the same cases.”
“Among _Leguminosæ_ a partial leafy condition (frondescence), or a more complete degree of the same change, (chloranthy) is not infrequent, particularly in _Trifolium repens_.”
“= -- Engelmann  pointed out that, so far as flowers were concerned, there are two ways in which they assume a green colour, either by a simple development of chlorophyll in place of the colouring matter proper to the flower, or by an actual development of leaf-like organs in the room of the petals -- frondescence.”
“As might be expected, frondescence of the petals is frequently accompanied by other changes of a similar nature in other parts of the flower, and sometimes by the abortion of the sexual organs.”
“On the whole, taking in consideration cases of partial frondescence, as well as those in which most of the parts of the flower are affected, phyllody would seem to be most common in the petals and carpels, least so in the case of the stamens and sepals.”
“These three groups will be found to include most of the forms under which frondescence of the clover blossoms occurs, but there are, of course, intermediate forms not readily to be grouped under either of the above heads.”
“Chloranthy, then, is a more complete form of frondescence.”
“Generally speaking, the disunion is complicated with frondescence -- but not always so.”
“Among _Umbelliferæ_ affected with frondescence of the pistil a similar increase in the number of ovules takes place.”
“Morren  judiciously proposed to keep these two conditions separate, calling the one virescence, the other frondescence (see p. 241).”
