BOTANY.

Macrorhynchus LessingiIj HooJc. & Am. Bot. Beech. j>. 361. Sea-beach at Monterey, Cali- 

 fornia ; April ; Parry. The specimen is in too early a state for prox)er investigation, but it has 

 a thick root, and very obtuse or rounded exterior scales of the involucre. Perhaps M. grandi- 

 florusj Nutt. (which is known only in fruit) is a fully developed state of it.

LOBELIACE^. 



Lobelia pectinata, Engelm, in Wisliz, Rep. p. 108. L. fenestralis, CavJ Sonora, Septem- 

 ber ; Thurher^ Schott. (No. 420 and 1430, Wright.) The plant of Cavanilles is said to be 

 perennial, while ours is certainly annual. 



Lobelia Berlanpieri, Alph. DG. Prodr. 7^ p. 367. On the lower Rio Grande, Chihuahua, 

 Neuvo Leon, etc. (No. 419 and 1429, Wright. No. 317Y, Berlandiery Matamoras.) Annual, 

 smooth. Stem erect, or sometimes apparently prostrate, more or less branching, mostly naked 



above. Lowest leaves broadly ovate or obovate^ tapering at the base into a petiole ; upper ones 

 sessile, ovate and oblong-lanceolate, irregularly and acutely toothed. Flowers in lax racemes 

 terminating the branches ; the pedicels 2-4 lines long and twice the length of the linear bracts. 

 Calyx about two thirds as long as the tube of the corolla, the segments subulate and denticulate. 

 Corolla blue, 3-4 lines long ; upper segments oblong-lanceolate ; lower ones much narrower ; 

 the tube about as long as the stamina. Wright's 419 and 1429, differ in being more leafy above, 

 and in the shorter pedicels. We suspect they are all forms of L. Cliffortiana. 



Lobelia puberula, Michx. Fl. 2, p. 152. Near Victoria, Texas. This is the same as No. 42 

 of Drummond's 3d Texan collection, which Alph. DC, refers to L. amcena» 



Lobelia laxiflora, H. B. K. 3, p. 311. L. fissa, Roem. & SchuUes. Mabibi, Sonera- 



June ; Thurher. About a foot and a half high. Leaves 3-5 inches long, lanceolate, acute at 



each end ; the lower ones remotely and obscurely denticulate ; the upper minutely and sharply 



serrulate. Raceme few-flowered. Pedicels an inch or more in length. Flowers nearly as 



P large as in L. cardinalis. Segments of the calyx triangular-lanceolate, scarcely longer than 



the hemispherical tube. Corolla dull red; the tube three times as long as the calyx. Stamineal 

 column considerably exserted.^ 



Lobelia cardi:n'alis, L. Sp. p. 1320. L. Texensis, Raf. Leon Spring, Devil's river and 

 Head of the Nueces, western Texas ; also on the Mimbres^ Neuvo Mexico ; Bigehia. The 

 flowers are sometimes smaller than in the northern plant ; in which state it seems to be hardly 

 distizict from L. Texensis, Ra/., except in the narrower flowers, and usually shorter sepals.
