34. Mr. J. Miers on the genus Leptoglossis. 
derably by the broad decurrent wings of the stigma, which hood 
the anthers of the somewhat shorter pair of stamens: the stigma 
is broad, membranaceous, deeply emarginate at its apex, consti- 
tuting two distinct rounded wi ngs, marked by numerous radia- 
ting nervures ; it forms altogether a galeate head, flattened on the 
under side and keeled on the upper surface by the prominent 
sharp margin of the style, which carinated edge is terminated in 
the sinus by a viscous globular gland. The capsule is small, 
consisting of two bifid valves, parallel to the dissepiment, and 
iclosed by the persistent calyx. I had no opportunity of exa- 
mining its seeds *, 
LEPToGLossIs. 
This genus was founded by Mr. Bentham, in the ‘ Botany’ of 
the Voyage of the Sulphur, for a Peruvian plant, which has not 
yet been figured, nor have the details of its structure been 
hitherto delineated or minutely examined. It possesses much 
the habit of a Browallia, to which it offers some resemblance 
in the form of its corolla; but it differs from that genus m 
having a fifth sterile stamen and in the shape of its stigma, 
which is intermediate between that of Pteroglossis and of Salpi- 
glossis or Nierembergia. No opportunity had presented itself for 
examining the eestivation of the corolla of Leptoglossis when I 
offered the remarks upon the tribe of the Salpiglossidee (Aun. 
Nat. Hist. 2nd Ser. 11.173) ; but recent observation has enabled 
me to state that it is decidedly imbricative, and as far as can be 
judged from well-macerated dried specimens, it is apparently of 
that modification which I have called replicative (Joc. cit. 173), 
the postical lobe being altogether interior, as in Nierembergia 
and Petunia. The alliance of Leptoglossis is clearly with the two 
latter genera, agreeing with the former in its small lanceolate 
leaves, its calyx, its slender tubular corolla, in the dilatation of 
its stigma, in the long stipitate support of the ovarium, in its 
persistent ‘hy pogynous “glands, and in its stipitate capsule. With 
the latter genus it agrees in the obliquity of the border of its 
corolla, and the somewhat palate-like enlargement of the tube 
below the throat. The position of Leptoglossis is manifestly 
among the Pefuniee, and not in the Salpiglossidea, as suggested 
in the tabular arrangement (/oc. cit. p. 165). It appears to me 
to hold no relation whatever to Schwenkia. 
The following generic character has been made, after a careful 
analysis of the plant referred to :— 
Lerroctossis, Bth.non D.C. Char. emend.—Calyz brevis, tu- 
bulosus, nervis 15 in seriebus 5 ternariis pressius ordinatis, 
* This plant, with its analytical details, will be shown in plate 52 of the 
‘ Illustr. South Amer. Plants.’
