348 BORAGINEZ. XXVIII. ExARRHENA. 
Glomerate-spiked Mouse-ear, or Scorpion Grass. Fl. May, 
Aug. Clt. 1812. Pl. 4 to 1 foot. 
T Species not sufficiently known. 
48 M. austra‘us (R. Br. prod. p. 495.) hispid; leaves ob- 
long-lanceolate ; calyxes equal to the tube of the corolla, beset 
with hooked hairs. (2?. H. Native of New South Wales, 
about Port Jackson; and of Van Diemen's Land. R. Br. says 
that the anthers are peltate in Myosotis, and that there is 
hardly any difference between it and Anchisa, unless in the one 
the racemes are bractless, and bracteate in the other. 
Southern Mouse-ear. PI. 
49 M. arPiwA (Lapeyr. abr. p. 85. fl. pyr. t. 64.) nuts 
smooth; stem simple, sub-bifid; flowers capitate; calyxes 
hoary from villi; leaves lanceolate, those at the bottom of the 
stem very villous. 2%. H. Native of the Pyrenees. This is 
a peculiar species. 
Alpine Mouse-ear. Pl. tufted. 
50 M. riscurA' rA (Lehm. asper. p. 110.) the specimen 
received by Lehmann under this name is nearly allied to M. 
palistris, and is probably the M. commutàta, Schultes. It has 
also been received under the name of M. uliginósa, Schrad. 
Lingulate-leaved Mouse-ear. Pl. 1. foot ? 
51 M. ramosissima (Rochel, Lehm. asper. p. 111.) stem 
much branched, beset with spreading hairs; floriferous branches 
beset with adpressed bristles; calyx divided beyond the middle, 
unequal, a little shorter than the corolla: with linear, hispid, 
obtuse segments. (2. H. Native country unknown. Flow- 
ers very small, blue. 
Much-branched Mouse-eaz. PI. 4 to $ foot. 
Cult. Some of the species of this genus are very delicate and 
beautiful when in blossom, as M. palistris, the Forget-me-not, 
M. rupéstris, M. répens, M. nana, and all the perennial kinds. 
They thrive best in moist places, or by the edges of ponds or 
ditches ; they also may be grown in pots and placed among the 
other alpine plants. ‘The annual species grow best in dry sandy 
soil, or on old walls where the seed may be sown. Most of the 
perennial species may be increased by dividing at the root, and 
all by seed. 
XXVIII. EXARRHENA (e£ ez, without ; and ain, arrhen, 
a male; in reference to the exserted stamens.) R. Br. prod. p. 
495. Lehm. asper. 76. 
Lin. syst. Pentándria Monogynia. Calyx 5-cleft. Corolla 
salver-shaped; throat closed by arched processes; limb 5- 
parted, obtuse. Stamens exserted; anthers peltate. Style 
length of stamens; stigma nearly simple. Nuts 4, distinct, 
1-celled, fixed to the bottom of the calyx, umbilicate at the 
base.—A pilose herb, with the habit of Myosotis, and differs 
principally from that genus in the exserted stamens. Leaves 
decurrent. Racemes conjugate or solitary, bractless. Flowers 
white, sweet-scented.

small pit, and oxeppua, sperma, a seed; in reference to a deep 
pit on the. inner side of each carpel.) Bunge, in mem. acad.

XXX. EcHINOSPERMUM. 
shaped; throat furnished with bifid, arched processes; tube 
short; limb 5-cleft. Anthers nearly sessile, oblong. Stigma 
capitate. Nuts 4, 1-celled, fixed to the bottom of the calyx, 
reniform, granular on the outside, perforated at the base, and 
deeply umbilicate on the inner side; each pit girded by a neck. 
—This genus is nearly allied to Myosotis, Exarrhéna and 
Borago. Habit of Myosótis. 
1 B. Cutne’nsz (Bunge, l. c.) 4. H. Native of China, 
near Pekin, among rubbish. Herb very hairy. Leaves oblong, 
entire, attenuated into the petioles. Racemes leafy. Flowers 
blue, like those of Myosdtis. All parts of the plant are more 
robust than most species of Myosótis. 
China Bothriospermum. PI. 1 foot? 
Cult. For culture and propagation see Myosdtis above. 
Susrrise II. CYNOGLO'SSEJE. Nuts fixed to the central 
column, not perforated at the base. 
XXX. ECHINOSPE’RMUM (from extvoc, echinos, a hedge- 
hog, and oveppa, sperma, a seed; in allusion to the seeds or 
nuts being echinated.) Swartz, ex Lehm. asper. p. 113. Blum.

Lin. syst. Pentándria, Monogynia. Calyx 5-parted. Corolla

scales; limb 5-parted, obtuse, spreading. Nuts 4, distinct, 
1-celled, triangular, compressed, echinated, fixed to the central 
column, not perforated at the base.—Scabrous, annual, or bien- 
nial-branched, erect plants. Leaves decurrent. Racemes brac- 
teate, terminal. Flowers small, blue. ‘The Linnean species 
of Myosótis, with echinated fruit, constitute a distinct genus, 
nearly allied to Cynoglóssum, from the nuts being adnate to the 
central column, but differs from that genus in the nuts being 
compressed, not depressed, and in the racemes being bracte- 
ate." R. Br. prod. p. 494.
