Echinopsis continued. 



shagginess which distinguishes the original species. Native 

 country unknown. (B. R. 1831, under name of Xchinocactut 

 Eyrietii glaucus. 



E. formosa (beautiful). Stem sub-globular or elongated, pale 

 green. Ribs obtuse, vertical, rounded, about sixteen in number ; 

 areolse distant, oval, greyish, rather woolly ; spines needle-like, 

 rigid ; two to four interior ones long, brown ; eight to sixteen

FIG. 698. ECHINOPSIS PENTLANDI LONGISPINUS. 



E. multiplex (multiplied).* fl. 6in. to Sin. long, and almost as 

 much across when fully expanded ; tube long, clavate, thickly 

 clothed at the base with short tufts of dense white hairs, while 

 the rest of the tube is beset with longer and dark-coloured 

 ones ; petals numerous ; outer ones narrow-lanceolate, gradually

becoming shorter and broader, so that the minuu ones an 

 almost ovate and acuminate, all of a delicate rose-colour, deeper 

 towards the apex ; anthers yellow, rounded. Plant marked with 

 about thirteen deep furrows and as many ridges, which are 

 prominent, acute, somewhat sinuated at the keel, and there beset 

 with thickly downy oval areohe , spines ten to twelve, the central 

 one longer and stronger than the rest, especially in the upper 

 areolse, where they are represented of a uniform deep tawny 

 colour, while those on the sides are more regular in size, and 

 variegated with dark brown and white. A. bin. South Brazil 

 (according to Pfeiffer). A very desirable plant, on account of the 

 delicacy and richness of colour of the petals. SY.N. Ceretu multi- 

 plex. (B. M. 5789.) 



E. oxygonos (sharp-angled), fl. proceeding from the furrows 

 about the foot of the stem, nearly 1ft long, reversed cone-shaped ; 

 tube somewhat curved, externally covered with bract* ; the lower 

 are small red, increasing in size, and at last terminating in the 

 petals, which are broad, lance-shaped, and of a roue-colour. 

 Plant nearly of a globular form, of a bluish-green colour. Ribs 

 fourteen, rising from a broad base, and running into an acute 

 edge ; the furrows are somewhat sharp spines, about fourteen, of 

 various sizes, the outer generally larger, the inner smaller, al! of 

 a brown colour, cone-like, not flat, the younger surrounded by a 

 tomentum which is more or less wanting in the older. Brazil. 

 (B. R. 1711, under name of Echinocacttu oxygonui.) 



E. Pentlandl (Pentland's). fl. bright rose-carmine. Summer. 

 Plant globular or sub-globular, with twelve or thirteen (rarely 

 with a larger number) acute, spiral, notched ribs, rather 

 glaucous-green ; areolie more or less crowded, woolly, furnished 

 with generally nearly equal spines. Peru, 1841 



E. P. longlapinus (long-spined). fl. crimson. Stem snb- 

 globular ; spines very long, dark brown. See Fig. 688. 



E. P. Sobeeiii (Scheer's). fl., petals yellow below, bright rose 

 above. Stem nearly globular ; spines long. See Fig. 699. 



ECHINOSFERMT7M (from echinos, a hedgehog, 

 and sperma, a seed ; referring to the prickly bur). SYNB. 

 Lappuln and Rochelia. OBD. Boraginece. A genus con- 

 taining about fifty species of annual, biennial, or peren- 

 nial, hispid or pu-bescent herbs, very few of which are 

 in cultivation. Flowers blue or whitish, usually small, 

 racemose or spicate. Leaves alternate, often narrow. 

 The species are most abundant in the temperate regions 

 of the Northern hemisphere. For culture, see Myosotia. 

 E. diffusum (diffuse), fl., corolla bright blue ; racemes commonly 

 loose and spreading, fr. a globose bur. I. oblong-lanceolate, 

 or the lowest spathulate, narrowed at base into long 

 wing-margined petioles ; the upper sessile, from oblong- 

 lanceolate to ovate or cordate, passing in to small bracts.

E. Lappula (Little Bur). This species has all the 

 ranee and the small flowers of a Myosotis, * 

 very rough triangular nuts. South Enr 



appearance and the small flowers of a Myosotis, but 

 with very rough triangular nuts. South Europe. 

 Annual. It has been occasionally found in isolated 



\ 



localities hi England, where it, no doubt, was acci- 

 dentally introduced. 



K. marglnatmn macranthum (large - flowered, 

 margined).* fl- pale blue, Myosotis-like ; racemes 

 many-flowered. 1. lanceolate, rough. Stems erect. 

 Russia. Biennial. (R, 0. 1119.) 



E. nervosnm (nerved). A synonym of R. di/tuwm. 



E. vlrginlcum (Virginian), fl., corolla slightly sur- 

 passing the calyx, pale blue or whit*, fr. globular, 

 armed all over with short prickles. 1.. radical ones 

 round, ovate or cordate, slender, petioled ; cauline 

 ones ovate-oblong to oblong-lanceolate, acuminate at 

 both ends ; uppermost passing into lanceolate bracts. 

 Stem 2ft to 4ft high, erect, with long and widelv 

 spreading branches. Canada to Louisiana. Annual.

ECHITES (from ech.it, a viper; referring 

 probably either to its deleterious quality or 

 its twining habit). OBD. Apocynaceoc. A genus 

 of about thirty-five species of handsome stove 

 evergreen twining shrubs, all natives of tropical 

 America. Flowers sub-corymbose; corolla sal- 

 ver-shaped, having a naked throat and tube, 

 with unequal segments; peduncles interpetiolar, 

 many-flowered. Leaves opposite; interpetiolar 

 cilia glandular. For culture, tee Dipladenia.
