 Leaves oblonir, sessile, pubescent, nearly entire, the radical ones spathulate ; 



stem erect, simple, pubescent; raceme spicate. Pastures and roadsides. 

 Plant slender I5 — 2 feet high, pubescent or nearly smooth. Stem somewhat 

 grooved, few-leaved, ending in a long, wand-like raceme. Flowers numerous, 

 on short pedicels, crowded, each axillary to a linear-lanceolate bract. Corolla

7. L. Ka'lmia. 



Smooth; stem simple, slender, erect; radical leaves spathulate, stnn leaves 

 linear-lanceolate, obtuse, remotely denticulate ; raceme lax, few-flowered, 

 leafy ; floioers pedicelled. A small and delicate species, inhabiting the rocky 

 banks of streams. Stem 6 — 12 inches high, commonly simple. Leaves 

 mostly linear, sessile, an inch long and 1 — 2 lines wide, upper ones entire, 

 lower wilii minute teeth. Flowers remote, alternate, on axillary pedicels 

 which are but little shorter than the leaf-like bracts. Corolla pale blue, the 3 

 lower segments obovate. Aug. Kalm's Lobelia. 



L. SPLENDENS and FULGENS, natives of Mexico, both with scarlet flowers, 

 are two other brilliant ornaments of this genus. They are occasionally 

 cultivated, as well as L. cardinalis. They require copious supplies of water, 

 in sanded bog-earth.

,S"(a.— Inserted with the corolla upon the calyx, equal in number to, and alternate with, its 



Anth. — Distinct, 2-cel!ed. Pollen spherical. 



Ot^a.— Adherent to the calyx, 2 or more-celled. Style covered with collecting hairs. 



Pr. — Capsule crowned with the remains ol the calyx, loculicidal. Seeds many. 



Herbs with a milky juice. Leaves alternate, exslipnlate. Flowers mostly blue, showy. 

 It is a small order, chiefly abounding in the northern temperate zone and in South Al'riea. 

 Of its 300 species, according to Alphonse DeCandolle, only 19 inhabit the torrid zone. 

 The campanulticea; are interesting cliiefly for their beauty, being destitute of any inip>!r- 

 lant known properties. They are represented among us by a single genus.

 Calyx mostly S-cleft ; corolla campanulate, S-lobed, closed 

 at base by 5 stameniforous valves; stigma 3 — 5-clcft; capsule 

 3 — 5-celled, opening by lateral pores. 



A Latin diminutive, from c«77i;>«n«, a bell ; a term singularly applicable to 

 the elegant form of the flowers. The divisions of the siigi7ia, as well as the 

 cells of the capsule are very generally 3. Seeds numerous and small. 



1. C. rotundifo'lia. 



Strm weak, slender ; radical leaves reniform-cordate ; cauline ones linear, 

 entire; flowers few, nodding. An exceedingly delicate plant, with blue, 

 bell-shaped flowers. On damp rocks and rocky streams. Stem a foot or 

 more high, smooth. The root leaves decay on the opening of the floweis, so 

 that only those of the stem are then visible. These are rather aumerous,
