spring, the fields and road-sides with their beautiful blossoms : 
for the same reason a hyacinth was called ayaWiQ. 
1. A. arvensis L. ( scarlet P. or Poor Man's Weather-glass') ; 
stems ascending or subprocumbent branched, leaves opposite or 
ternate ovate sessile dotted beneath, peduncles longer than the 
leaves, calyx nearly as long as the rotate corolla. — a. margin 
of the corolla crenate piloso-glandulose. E. B. t. 529. — (3. 
crerulea; margins of the corolla toothed scarcely at all glandu- 
lose. A. cterulea Schreb. : E. B. t. 1823. 
Corn-fields, frequent. — /3. rare in similar situations, and principally 
in England. ©. 5 — 11. — Flowers generally bright scarlet, some- 
times blue, sometimes flesh-coloured ; and Mr. Dillwyn Llewellyn has 
found, at Penllegare, S. Wales, specimens with the flowers pure white, 
and a small, well-defined, bright purplish-pink eye in the oentre of 
every corolla. The Rev. Professor Henslow has proved, by cultiva- 
tion from seed, that A. cwrulea and A. arvensis are varieties of the 
same species : on the other hand, Mr. Borrer is of opinion that our 
two varieties are distinct species, but that each varies with the same 
tints of colour. 
2. A. tenella L'. (Bog P.) ; stem creeping filiform, leaves 
opposite ovate or roundish stalked, peduncles longer than the 
leaves, calyx four times shorter than the broadly and widely 
funnel-shaped corolla. E. B. t. 530. 
Wet mossy bogs, frequent in England, more rare in Scotland. 
y. 7,8. — A beautiful little plant, as are all of this genus, Si — 4 
inches long. Leaves small. Flowers large in proportion to the size 
of the plant, on rather long footstalks. Cor. rose-colour. Filaments 
slightly connected at the base. 
8. Centunculus Linn. Chaffweed. 
Cal. 4-partite. Cor. with a globose inflated tube; limb spread- 
ing, 4-partite. Stum. 4, short, beardless. Caps, bursting all 
round transversely. (Leaves alternate. Flowers sessile.) — 
Name, it appears, anciently given to the pimpernel , a genus 
allied to this ; and derived, according to Thcis, from cento , a 
patchwork , from the way in which it covers the ground. 
1. C. minimus L. (small C., or Bastard Pimpernel) ; leaves 
ovate mucronate sessile. E. B. t. 531. 
Moist sandy or gravelly places about London, in Kent, Bedfordshire! 
Norfolk, Suffolk, Hampshire, the south of Ireland, and Lowlands 
of Scotland, but not frequent ; probably, however, often overlooked 
on account of its small size. ©. 6, 7. — Plant 1 — 2 inches high, 
more or less branched. Leaves alternate, ovate, glabrous. Flowers 
extremely minute, sessile, axillary, solitary. Cor. pale rose-colour, 
withering. Perhaps the only species of the genus, C. lanceolatus of 
N. America being scarcely distinct.
