 p. 99. This is assuredly only a variety of /. d.phylla. We 

 have met with them both growing in the same spot, and 

 passing into each other by insensible gradation*, 



(7) Lndurigia *pohjcarpi. Erect, much branched; leaves 

 narrow4anceolate, acute at each end, alternate, glabrous; flow* 

 ersapetalous? clos le, axillary and congregated; cap- 

 sules spherical, two-leaved. 



Description: Stem erect, 1 to 3 feet high, angled and very 

 branching, branches of irregular length and irregularly dispo- 

 sed. Leaves narrow-lanceolate and very acute, alternate, 

 sub-sessile, glabrous on both surfaces and scabrous on the mar- 

 gin; the lower ones 4 inches long by i inch wide, diminishing 

 upwards. Flowers apetalous? axillary and closely sessile, 

 generally solitary, but frequently collected in confused heads on 

 the main stem, or smaller branches; capsules spherical, slightly 

 angled, with two small, narrow, lanceolate, serrulate leaves 

 seated on it, near the base; leaves of the calyx shorter than 

 the capsule. 



Discovered by Mr. H. A. Griswold in the wetlands around 

 Louisville, where it occurs in greatabundance, flowering from 



to October. This species certainly bears considerable 



affinity to the L. mollis as described by Elliott, but it differs 

 from that in being altogether destitute of the characteristic 

 villosity, and in having an angled stem. We have therefore 

 given it a name from the profusion of its capsules — a greater 

 profusion by far than is borne by any other species within our 

 knowledge. 



(8) Pontederia. cordata, var, ^allnflora. Our friend and fel- 

 low-labourer, Mr. Griswold, pointed out this variety to us in a 

 pond near Louisville. It there occurred in company with the 

 common blue or purple flowered species, from which it seems 

 to differ only in the colour of its flowms, which is a pure white, 

 with a slight tinge of pink. 



(9) Pinus variabilis, Rhus typhinum, Rosa gemeHa, Sfc. These 

 species have not been met with by ourselves, within the limits of 

 this state: they are introduced into this Catalogue on the au-
