tifully propagated by parting the roots in October when the 

 stalks begin to decay. They love a moist soil, and should 

 be allowed room ; for if they are too near other plants, they 

 will be robbed of their nourishment.

Ruellia; a genus of the class Didynamia, order Angio- 

 spermia. GENERIC CHARACTER. Calix: perianth one- 

 leafed, five-parted, permanent; segments linear, acute, 

 straight, permanent. Corolla: one-petalled, irregular, with 

 a patulous inclined neck; border five-cleft, spreading, blunt, 

 with the two upper segments more reflexed. Stamina : fila- 

 menta four, placed where the tube widens, approximating 

 by pairs; antherse scarcely longer than the tube. Pistil: 

 germen roundish; style filiform, the length of the stamina; 

 stigma bifid, acute, the lower segments rolled in. Pericarp: 

 capsule round, acuminate both ways, two-celled, two-valved, 

 opening elastically by the claws; partition contrary. Seeds: 

 a few, roundish, compressed. Observe. In some species 

 there is the rudimentum of a fifth stamen. ESSENTIAL 

 CHARACTER. Calix: five-parted. Corolla: subcampanu- 

 late. Stamina: approximating by pairs. Capsule: opening 

 by elastic teeth. The species are, 



1. Ruellia Blechum; Hairy-leaved Thick-spiked Ruellia. 

 Leaves ovate, serrate-toothed, somewhat hirsute; spikes ovate; 

 inner braetes in pairs; flowers three together, sessile; seeds 

 black. This annual plant is common in pastures and bushy 

 places in Jamaica. Like most of the other species, it is pro- 

 pagated by seeds, which must be sown early in the spring 

 in pots filled with light rich earth, and plunged into a mod-c- 

 rate hot-bed ; and when the plants come up, they must be 

 ' transplanted each into a separate small pot filled with rich 

 earth, and plunged into a hot-bed of tanners' bark, where 



they must be shaded from the sun until they have taken new 

 root; after which time they must have free air admitted to 

 them every day in warm weather, and be constantly watered 

 three or four times a week during the summer. If they suc- 

 ceed well, the eighth and eleventh species will produce flowers 

 in the following July, and perfect their seeds in August : 

 but the roots will continue, provided they are plunged into 

 the bark-bed in the stove, and kept in a moderate tempera- 

 ture of heat. If the seeds be peimitted to scatter, as their 

 pods discharge them with a violent spring into the neighbour- 

 ing pots, the plants will come up without care, and may be 

 transplanted into pots filled with fresh loamy earth, and 

 plunged into the tan-bed. 



2. Huellia Blechioides ; Smooth Thick-spiked Ruellia. 

 Leaves oblong, somewhat toothed, smooth ; spikes ovate ; 

 flowers longer than the braetes ; stems prostrate, dichoto- 

 mous, even, slightly four-cornered. Browne says, that this 

 plant is pretty frequent in most dry and shady places, among 

 the lower hills of Jamaica; that it thrives best in a gravelly 

 soil, but seldom rises above two feet and a half in height. 

 See the preceding species. 



3. Ruellia Angustifolia ; Narrow-leaved Ruellia. Leaves 

 linear-lanceolate ; spikes oblong ; braetes ovate, hirsute. 

 Native of the West Indies. 



4. Ruellia Strepens ; Whorl-flowered Ruellia. Leaves 

 petioled ; peduncles three-flowered, short; root fibrous, per- 

 ennial; stems about a foot high. It acquired the epithet 

 Strepens from the crashing sound which the leaves make 

 when handled, on account of their very dry nature. Flowers 

 axillary, two or three from the same point, sitting very close 

 to the stalk, small, of a pale purple colour and very fuga- 

 cious, opening early, and gone by ten or eleven in the fore- 

 noon. They appear in July and August. Native of Vir- 

 ginia and Carolina. It is not a plant of long continuance, 

 seldom lasting longer than two years ; but if treated as 

 directed under the first species, it will ripen seeds in the 

 second year, and may then be easily propagated. 



5. Ruellia Macrophylla; Long-leaved Ruellia. Leaves 

 ovate, lanceolate, acuminate, quite entire; peduncles axil- 

 lary, elongated, two-flowered ; stem four-cornered, pubes- 

 cent, seemingly herbaceous. Native of Santa Martha. 



6. Ruellia Patula; Spreading Ruellia. Shrubby, villose, 

 viscid: leaves ovate, quite entire; flowers axillary, aggregate. 

 The whole plant is very fetid, and somewhat villose, as also 

 is the calix. Corolla dirty flesh-colour ; it emerges from the 

 calix in the evening, is fully expanded next morning, and falls 

 before the return of night. Native of the East Indies. 



7. Ruellia Pallida; Pale-leaved Ruellia. Leaves petioled, 

 ovate, wave-crenate, rugged at the edge ; flowers axillary, 

 solitary, sessile, large and violet- coloured. Native of the 

 West Indies. See the first species. 



8. Ruellia Clandestina; Covert-flowered Ruellia. Leaves 

 petioled; peduncles three-flowered, long, subdivided, naked; 

 root perennial, composed of many fleshy fibres. -Native of 

 Barbadoes, where it is called Snap-dragon, from the bursting 

 of the seed-vessels. It flowers here in July and August. 

 See the first species. 



9. Ruellia Paniculata; Panicled Ruellia. Leaves almost 

 entire; peduncles dichotomous, divaricate, pauicled ; root 

 perennial; stems four or five feet high, much diffused; flowers 

 at the divisions of the stem, small, purple, of short duration. 

 The whole herb is somewhat clammy with glands, and has 

 an odour approaching to that of camphor. Dr. Patrick 

 Browne says, it is common about Spanish Town in Jamaica, 

 and iu many other parts of the low lands, where it generally 

 blows in the months of December atid January, making a
