in outline, and probably subglobose in the living state, very obtuse ; 
staminal column % lin. long; anthers erect, quadrate, their appen- 
dages-reniform, erect, applied to the margin of the very dilated 
style-apex,and their wings small and nearly concealed by the corona- 
lobes ; style-apex dilated so as to somewhat overhang the anther- 
cells, truncate, cushion-like, slightly depressed in the centre.

Very similar to X. prunelloides, Turez., in general appearance, but the 
different colour of the rotate (not campanulate) corolla, and the very different 
corona-lobes, easily distinguish it. 
Imperfeetly known species.

XIII. PERIGLOSSUM, Decne. 
Calyx 5-partite. Corolla 5-lobed nearly to the base; lobes 
narrowly overlapping in bud. Corona of 5 lobes arising at the base 
of the staminal column, alternating with the corolla-lobes, very 
shortly connate at the base, erect, spathulate-oblong, spathulate- 
sagittate or linear-oblong, with a transverse ridge or flap and often 
2 keels on the inner face, with a long and distinct or minute and 
rudimentary slender filiform process alternating with them at the 
base. Staminal column arising from the base of the corolla, sub- 
globose from being constricted at the apex and base ; anthers with a 
broad thin and membranous connective, terminated by a membranous 
appendage, the cells firmer, extending quite to the base of the 
¢olumn, slightly inflated and much curved. outwards, not horny on 
the margins, except at the apex, where they project as small 
triangular acute wings. Pollen-masses solitary in each cell, pendu- 
lous, subclavately subterete, semicireularly curved, opaque at the 
attached end, much flattened and semitransparent at the truncate 
free end, attached in pairs to a very minute black horny pollen- 
carrier by rather stout caudicles, which are twice as long as the 
pollen masses, but entirely contained in the anther-cells, doubly 
curved or somewhat §-like, enlarged’ and slightly excavated where
