of a leafy structure (the funicle) bearing the inner integument, subtended 
by the rudimentary sheath of the outer integument, on its lower surface 
(Fig. 8) ; or, in some cases, the outer integument may be completely ab- 
sorbed in the funicular lamina. (For all details, both in this and other 
cases of abnormal ovules described by our author, the reader is referred 
to the original papers, which amply illustrate the various stages of the 
metamorphogenesis.) In the case of Trifolium repens it was also the funicle 
which chiefly proliferated, assuming the form of a bilobed structure at the

inner integument, bearing the nucellus on its upper surface and an adventitious shoot ( ad) at its 
base. Fig. 10. Trifolium repens : ovule in which funicle has proliferated, bearing inner 
integument in sinus between its two lobes (cf. Fig. 16). Fig. ii. Trifolium repens : virescent 
ovule proliferated as three-lobed leaflet. Fig. 12. Hesperis matronalis : virescent ovule with 
proliferated outer integument bearing inner integument on its lower surface. Fig. 13. Hesperis 
matronalis : proliferated outer integument bearing several inner integuments on its lower surface

base of whose sinus sometimes occurred the small sheath of the outer 
integument (from the upper surface of which the funicular lamina is an out- 
growth), enclosing the weakly-developed inner integument either in the 
form of a cup-shaped organ or as a simple leaflet bearing the nucellus on 
its upper surface (Figs. 10, 11). This is a very important stage, and will 
be referred to hereafter,
