scabrously papillose, a quality which it enjoys equally well 
with the dorsum of the style. "The termination of the vessels 
is just within the apex. 
The limits of the two surfaces are, however, distinct in 
opaque views, the papille of the stigma being marked out 
by a yellower line; they are likewise more thick set and 
smaller than those on the dorsum of the style. 
In Myriogyne, a similar thing takes place; the stigmata 
are lanceolar, and the distinction between style and stigmata 
is very obscure, the papillz of style are the largest: the ves- 
sels end as usual. 
Mazus rugosus. The style is divided at the top into 
lamellz, of which the lower is biggest; the whole inner faces 
and margin of these are very papillose; the vessel of each, 
ends rather below the middle. Papillze become smaller and 
smaller toward mouth of stigmatic canal. 
In Medicago minima, the lower margin of the dorsum 
of the ovarium is very gibbous. "The ventral suture is near- 
ly straight, the opposite in this respect of Melilotus. The 
stigma is obliquely capitate, the obliquity is opposite to the 
ventral suture. The venation is 1 dorsal, 2 marginal, all 
incomplete, and none produced any distance up the style. 
Pl: 33—Fig. 7. a, dorsal vein, b, lower margin. 
In Anagallis, the style is undivided, 5 vascular vessels 
with clavate subdistinct ends occur, and the stigma consti- 
tutes a papillose rim at the end of the canal ; the ovarial ves- 
sels are 10, 5 dorsal, and 5 interstitial. The number of style 
vessels is obscured by the occasional passage of one of the 
interstitial vessels. The stamina are much earlier in deve- 
lopment than the petals, and the stigma is mature in outline 
at a very early period. The anthers are bilocular, loculi 
bi-locellar. side by side, but rather obliquely. "The stigmatic 
surface extends not only from the rim, but from the conduct- 
ing tissue itself. Pl. 33— Fig. 15. a, section of style, 5,—5,, 
Eclipta, presents linear stigmata, occupying the whole in- 
ner face, and confluent beyond the apex of the vessel. 
Ranunculus acris. Stigma oblique, papillose, disappear- 
ing gradually down the ventral suture.
