in diameter, with strap-shaped ray florets 

 hearing a pistil only, and tuhular disc florets 

 having hoth stamens and pistil. The 

 pappus is made up of three unequal scales. 

 The flowers are yellow. [A. A. B.] 



CALLIOPSIS. A genus of plants he- 

 longing to the composite order, distin- 

 guished from their allies hy the invo- 

 lucre or covering which surrounds the 

 heads of the flowers being formed of two 

 rows of scales, the outer short and spread- 

 ing, the inner larger erect and united at 

 the base. The receptacle or part support- 

 ing the flowers is flat, having on it narrow 

 scales which fall early and are shorter 

 than the flowers. The fruit is truncated, 

 incurved, destitute of appendages. The 

 name is from two Greek words which 

 together signify ' beautiful eye, aspect, or 

 appearance,' in allusion to the general 

 elegance of the species or the eye-like spot 

 on the flowers. The genus comprehends 

 a number of interesting herbaceous plants, 

 natives of North America, several of which 

 were, and indeed still are, referred by some 

 authorities to the genus Coreopsis. They 

 are usually free from hairs, the leaves 

 opposite, more or less divided ; the flowers 

 at the circumference of the heads yellow, 

 with a dark purple or rose-coloured spot at 

 the base, those in the centre yellow or 

 purple. The elegance of the flowers, so 

 marked in these plants, renders them de- 

 sirable in flower-beds. The more hardy 

 species, whether annual or perennial, are 

 generally of easy cultivation. C. rosea has 

 been long known, and may be specially 

 alluded to as an example of the genus; 

 having the stem smooth, leaves opposite, 

 long and narrow, the heads of flowers 

 small on short stalks. [G. D.] 



CALLIPELTIS. An annual erect much- 

 branched slender herb belonging to the 

 order Bnbiacece. The flowers grow in 

 whorls of six, and are whitish four-parted 

 and bell-shaped. The fruit, which is one- 

 seeded by abortion, is partially enveloped 

 by a large hollow membranous bract. The 

 leaves and leaf-like stipules form whorls 

 of four. C. CHCiiUaria, the only species, a 

 native of the Levant, is an unimportant 

 plant growing from six to twelve inches 

 high. [C. A. J.] 



CALLTPHYSA. A genus of Polj/gona- 

 cece, differing from Callhionum only by 

 having the nut not winged at the angles 

 but rounded, and covered with bristles, and 

 expanded at the apex Into a bladder-like 

 envelope to the nut. [J. T. S.] 



CALLIPRORA. A genus of liliaceous 

 plants, found in California, and consisting 

 of dwarf bulbous herbs with small radical 

 linear-ensiform leaves, and bearing the 

 flowers in umbels at the top of a scape. 

 The perianth is bell-shaped, six-parted, 

 with equal-spreading segments ; it is fur- 

 nished with six stamens, all perfect, with 

 petaloid bilobed filaments, the alternate 

 ones shorter, and the anthers sessile be- 

 tween the lobes ; and it has a stalked three- 



celled ovary containing many ovules, and 

 surmounted by a three-lobed stigma. C. 

 Ivied, the only species, is a dwarf plant, 

 producing umbels of yellow star-shaped 

 flowers resembling those of an Omitho- 

 galum. [T. M.] 



CALLIPSYCHB. A genus of AmarvlU- 

 dacea?, founded on a Mexican species allied 

 to Eucrosia, and named C. eucrosioides. 

 The plant has roundish bulbs, furnished 

 with a few green tessellated and pitted 

 leaves, a foot long and four inches wide, 

 and produces at a different season, before 

 the leaves are developed, a glaucous scape 

 upwards of two feet high, bearing an um- 

 bel of declinate flowers, which are stalked. 

 The perianth consists of a short green 

 tube, full of honey, and an erect regular 

 limb nearly an inch long of bright red 

 segments, the sepaline of which are boat- 

 shaped, and the petaline obtuse. The six 

 stamens are pale green, and with the style 

 are about four times as long as the perianth. 

 The filaments are free, inserted in the 

 mouth of the tube, and are tuberculate 

 at the base. In our gardens the leaves die 

 away in the autumn, and the flower-scapes 

 appear in spring before they are again 

 developed. [T. M.] 



. CALLTPTERIS. A genus of polypodia- 

 ceous ferns of the group Aspleniece. They 

 belong to the diplazioid series, having the 

 sori more or less abundantly and constantly 

 placed in pairs back to back on the same 

 vein ; and are specially distinguished in 

 the typal group by having the veins joined 

 together in a connivent manner, that is, 

 the main veins that spring out from the 

 midrib are parallel, and the venules which 

 branch out from them set off at an angle 

 and meet the opposite ones in the centre, 

 and so form a series of acute angles one 

 above the other. In one group the 

 junction of the veins is less regular and 

 frequent. The species, ten or twelve in 

 number, are almost all found in the east- 

 ern tropics, but one or two occur in the W. 

 Indies and S. America. They are gene- 

 rally large growing plants with coarse 

 pinnated or twice or thrice-pmnatedfronds, 

 the rachis sometimes proliferous. [T. MJ 



CALLIRHOE. A genus of beautiful 

 North American mallow-worts, comprising 

 several perennial herbaceous species, some- 

 times known by the name of Nuttallia, 

 which, however, belongs to a genus of 

 Rosacea?. They are very nearly allied to 

 Malva itself, from which they differ in 

 certain slight technical peculiarities of the 

 fruit ; and also in some of the species, by 

 wanting the involucel or whorl of bracts 

 which, is found exterior to the calyx in 

 many of the genera of this order. * The 

 involucel, when present, consists of from 

 one to three bnicts, which are sometimes 

 remote from the flowers. The calyx is 

 five-cleft ; the corolla five-petaled. the pe- 

 tals truncately wedge-shaped, and often 

 eroscly-toothed at the tip. The filaments 

 of the stamens are united into a columnar 

 tube which bears a tuft of many stamens
