F em a l e F r u c t if ic a t io n te rm in a l upo n th e stems and branches.
Calyx (f. .5) nearly th re e q ua rte rs o f a line lo n g , a t tlie base cylindiical, o r, when th e
ge rm en has aiTived a t its fu ll size, ventricose, thenc e becoming depressed and quite
fiat a t tlie m o u th , which is tru n c a te and entire . I n texture an d color th e caiy.x
corresponds with the leaves.
Calyptra (f. 7 ) obovate, membranous, lu tieula ted, tip p ed w ith a sh o rt tu b u la r style. At
its base a re a few sh o rt and nearly lineai' barren pistilla.
Peduncle ab o u t half an inch long, white, suc culent, s tria ted transvei-sely a nd longitudinally.

At th e tim e when th e pla te o f J. umbrosa was engraved, my Scotch specimens o f this e leg an t
species o f JungeiTnannia, were th e only ones k n own as B r itis h ; b u t I have since been able
to make considerable additions to my description o f th e p lan t, by means o f others which I have
lately received from Dr. Taylor an d Mr. Mackay, g a tlie red in a fine s ta te , and co n ta ining
both male and female fructification. All o f th em ag re e well with au th en tic indi?dduals sen t
to Mr. T u rn e r by D r. S chrader, as well as with th e admirable cha ra c te r o f it , given by th e
la tte r gen tlem an in his Syst. Samml. Kryp t. Gewdsche.
T h e p lan t has a peculiarly handsome appearance, from th e recurved leaves a t th e apices
o f th e stems and branches, wliich is more s trik in g in th e you n g shoots. I t is distinguished
from its associate, J . nemorosa, by th e more na rrow lobes o f th e leaves, tliefr more ovate figure,
and especially by th e ir b e in g tru ly se rra ted {by no means d e n ta to -c ilia te ), and by th e en tire
m o u th o f th e calyx.
