BOTANY. 107 
MACRORHYNCHUS LESSINGII, Hook. Ф Arn. Bot. Beech. p. 361. Sea-beach at Monterey, Cali- 
fornia; April; Parry. The specimen is in too early a state for proper investigation, but it has 
a thick root, and very obtuse or rounded exterior scales of the involucre. Perhaps M. grandi- 
florus, Nutt. (which is known only in fruit) is a fully developed state of it.

LYGoDESMIA APHYLLA, DỌ., уат. TEXANA, Torr. & Gray, Fl. 2, p. 485. Common on plains 
from San Antonio, Texas, nearly to the Rio Grande, New Mexico. The stems bear long leaves 
towards the base.

Grande, and Cobre, New Mexico.

LOBELIACEJE. 
LOBELIA PECTINATA, Engelm. in Wisliz. Rep. p.108. L. fenestralis, Cav.? Sonora, Septem- 
ber; Thurber, Schott. (No. 420 and 1430, Wright.) The plant of Cavanilles is said to be 
perennial, while ours is certainly à TC 
LoBELIA BERLANDIERI, Alph. DC. Prodr. Т, р. 367. On the lower Rio Grande, Chihuahua, 
Neuvo Leon, etc. (No. 419 and 1429, Wright. No. 3177, Berlandier, 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. Wrighé'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, Micha. 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. amena. 
LosELIA LAXIFLORA, H. B. К. 3, p. 311. L. fissa, Roem. d: Schultes. Mabibi, Sonora; 
June; Thurber. About a foot anda 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 
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 CARDINALIS, 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; Bigelow. The 
flowers are sometimes smaller than in the northern plant ; in which state it seems to be hardly 
distinct from L. Texensis, Raf., except in the narrower flowers, and usually shorter sepals.
