T h e Calyx (f. f. 9. 10) is obovate, o f th e same color and texture as th e leaves, sliglitly

This little species ha s been detected bo th in Ii'eland and in Scotland. I ts m in u te size

to g e th e r w ith its la rg e stipule s, and th e prom in en t situa tion o f these, and th e ir figure, afford
s trik in g c h a ra c te rs ; though, in th e la tte r p a rticu la r, i t very ne a rly corresponds w ith another
new species {J . Bantricnsis, mss.) which has lately been discovered by Miss Hu tch in s, and
which has, like th e p re sent, emargina te le av e s ; b u t i t diffei's in its m uch g re a te r dimensions,

stem , as th a t o f J . pusilla does. I m u st here mention an o th e r species, found in Scotland by
Mr. Lyell, which has considerable affinity w ith th e p re sent in the size o f th e stipules, and
still more so in th e ir fo rm : b u t, besides th a t its leaves a re twice o r thric e as la rge as those
o f J . stipulacea, th ey afford a more decisive ch aracter in the ir obtuse segments. With th e

fa r th e most excellent account o f this species is given by Dillenius, th o u g h I cannot find th a t th e
difference, mentioned by this celebrated author, in th e leaves o f his fig. 33 exists, even in his own
specimens. H a lle r is by no means correct in his remark upon Micheli, where he says, “ .Siimmos
ramos te rm in an t compressæ gemmæ, Brizæ locustis similes, quas pro fructibus -Micbelius habet:
veros taiiien juniores ramos esse, cx foliis serratfe commissis facile agnoscas:” nor is he less in accurate,
when, in speaking o f the calyces, he describes them as “ rotundi and bivalves”. In bis
var. fi. (our Thuja), he falls into th e same error as Dillenius, in a ttrib u tin g to i t cordate leaves
in opposition to those of « , ivliich he says are ovato-lanceolate. Lamarck,, in th e Encyclopédie, had
u n ited this species with his J . cupressiformis * , making our a th e fi of th a t p lant, and our var. Thuja
th e y o f it. In th e Flore Françoise this excellent na tu ra list has restored the name platyphylla. The
f a r . Thuja, however, is unnoticed in th a t work, from which, probably, we may infer th a t it is n o ta
native o f France.
