BORAGINEjE. XXVIII. EXAKRHENA. XXIX. BOTIIRIOSPERMUM. XXX. ECHINOSPERMUM. 



Glomerate-spiked Mouse-ear, or Scorpion Grass. Fl. May, 

 Aug. Clt. 1812. PI. | to 1 foot. 



f" Species not sufficiently known. 



48 M. AUSTRA'LIS (R. Br. prod. p. 495.) hispid; leaves ob- 

 long-lanceolate ; calyxes equal to the tube of the corolla, beset 

 with hooked hairs. O ? H. Native of New South Wales, 

 about Port Jackson ; and of Van Diemen's Land. R. Br. says 

 that the anthers are peltate in Myosbtis, and that there is 

 hardly any difference between it and Anchusa, unless in the one 

 the racemes are bractless, and bracteate in the other. 



Southern Mouse-ear. PI. 



49 M. ALPINA (Lapeyr. abr. p. 85. fl. pyr. t. 64.) nuts 

 smooth ; stem simple, sub-4>ifid ; flowers capitate ; calyxes 

 hoary from villi ; leaves lanceolate, those at the bottom of the 

 stem very villous. % . H. Native of the Pyrenees. This is 

 a peculiar species. 



Alpine Mouse-ear. PI. tufted. 



50 M. LINGUI.A'TA (Lehm. asper. p. 110.) the specimen 

 received by Lehmann under this name is nearly allied to M. 

 palustris, and is probably the M. commutata, Schultes. It has 

 also been received under the name of M. uliginbsa, Schrad. 



Lingulate-\ea.ved Mouse-ear. PI. 1 . foot ? 



51 M. RAMOSISSIMA (Rochel, Lehm. asper. p. HI.) 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. Q. H. Native country unknown. Flow- 

 ers very small, blue. 



Much-branched Mouse-ear. PI. 5 to | foot. 



Cult. Some of the species of this genus are very delicate and 

 beautiful when in blossom, as M. palustris, the Forget-me-not, 

 M. rupestris, M. repens, 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. EX ARRHE'N A (tt,ex, without; and atfnv, arrhen, 

 a male ; in reference to the exserted stamens.) R. Br. prod. p. 

 495. Lehm. asper. 76. 



LIN. SYST. Pent&ndria 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 Myosbtis, and differs 

 principally from that genus in the exserted stamens. Leaves 

 decurrent. Racemes conjugate or solitary, bractless. Flowers 

 white, sweet-scented. 



1 E. SUAVE'OLENS (R. Br. 1. c.) O ? H. Native of Van 

 Diemen's Land. Lehm. asper. 1. c. Myosotis suaveolens, 

 Poir. suppl. 4. p. 44. 



Sweet-scenled-fiowereA Exarrhena. PL 



Cult. For culture and propagation see Myosotis above. 



XXIX. BOTHRIOSPE'RMUM (from /3o0piov, bothrion, a 

 small pit, and airtpiia., sperma, a seed ; in reference to a deep 

 pit on the inner side of each carpel.) Bunge, in mem. acad. 

 petersb. 2. p. 121. 



LIN. SYST. Pentandria, Monogynia. Calyx 5-parted, perma- 

 nent at length, a little widened or increased. Corolla salver- 



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 Myosbtis, Exarrhena and 

 Borago. Habit of Myosotis. 



1 B. CHINE'NSE (Bunge, 1. c.) $ . 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 Myosotis. All parts of the plant are more 

 robust than most species of Myosotis. 



China Bothriospermum. PI. 1 foot ? 



Cult. For culture and propagation see Myosotis above. 



SUBTRIBE II. CYNOGLO'SSEjE. Nuts fixed to the central 

 column, not perforated at the base. 



XXX. ECHINOSPE'RMUM (from tx lt ">e> echinos, a hedge- 

 hog, and (TTrepjua, sperma, a seed ; in allusion to the seeds or 

 nuts being echinated.) Swartz, ex Lehm. asper. p. 113. Blum,

LIN. SYST. Pentandria, Monogynia. Calyx 5-parted. Corolla 

 salver-shaped, or funnel-shaped ; throat furnished with short 

 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-branchad, erect plants. Leaves decurrent. Racemes brac- 

 teate, terminal. Flowers small, blue. " The Linnean species 

 of Myosotis, with echinated fruit, constitute a distinct genus, 

 nearly allied to Cynoglossum, 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. 



1 . Fruit drooping, or deflexed. Racemes almost bractless.
