In this latter communication, published as this sheet is pa.s.sing through the press, the author gives an interesting account of the transitional stages between the ordinary papilionaceous condition and the regular form which is like that of a Rosaceous plant. The peloric form is stated to be transmitted by seed.

FOOTNOTES:

[232] 'Amoen. Acad.,' i, p. 55, t. iii (1744):--The following note refers to Linne's notion that these forms were due to hybridization. It is extracted from Gmelin's edition of the 'Systema Naturae,' 1791, p.

931. "_Linariae_ proles hybrida, ejusdemque qualitatis et constans, radicibus infinite sese multiplicans charactere fructificationis diversissima, corolla regulari, quinque-corniculata, pentandra, ut genus proprium absolute const.i.tueret et distinctissimum, nisi fructus frequentissime abortiret. Naturae prodigium. Ita quidem a Linne.

Verisimilor autem videtur ea opinio, quae peloriam pro peculiari degeneratione monstrosa floris habet, in quam inclinare hoc genus (Linaria) prae aliis, similis a forma deflexio in aliis speciebus, e.g.

_spurio Elatine_, _cymbalaria_, observata, ... Merk., 'Goett. gel.
