Var. 8. apiculata : corolla somewhat granulate, ovary and 1-seeded capsule conic, apiculate ; otherwise very 
similar to the last. — On the Colorado, Bigelow! in February. 
Var. €. ? squamigera : flowers 2-2J lines long, on pedicels shorter than the flower, or even the calyx, in rather 
crowded subglobose clusters; lobes of calyx lanceolate, acuminate, as long as the open, funnel-shaped tube of the 
corolla ; lacmise lanceolate, as long as the tube* at last spreading ; anthers oblong-linear, cordate at base, on very short 
filaments ; scales spatulate, fringed, shorter than the tube, incurved ; styles as long as the very acute ovarium • capsule 
apiculate, 1-seeded, lower half enveloped by the tube of the corolla. - The more densely clustered flowers the 
presence of scales and the acute ovarium would seem to specifically distinguish this form, but the last mentioned variety 
appears to unite it with the common form ; perhaps it ought to be classed with the next species. — Saline soil on the

This fine and large-flowered species resembles different forms of G. corymbosa and G. odontolepis so much, that I felt 
considerably inclined to unite all of them as varieties of one and the same species ; but then the dehiscence or non- 
dehiscence of the capsule would have to be considered as a character of not even specific importance; there are how¬ 
ever, also other differences, so that these species must be viewed as representing different types under a similar external 
lorm. Flowers 2-3 lines long, on very short pedicels or almost sessile, paniculate-glomerate, at last forming large and 
ra her dense clusters ; cylindrical tube of corolla longer than the deeply divided calyx ; lobes fleshy, ovate-lanceolate, 
acutish, imbricate; lacmise ovate, acute, more or less crenulate, shorter than the tube, erect or patulous; anthers oblono- 
or ovate, cordate usually longer than the filaments, or even subsessile ; scales scarcely reaching above the middle of the 
tube, spatulate-oblong, deeply fnnged; styles slender, much longer than the 2-pointed ovaiy, at first scarcely exsert • 
capsule oval 1-2-seeded, its upper part capped by the withered corolla ; seeds 0.7-0.9 line in diameter, rough, oval or 
subglobose, oblique or almost hooked, with a very small oblong hilum.

absolutely identical with those from the salt marshes of the coast; the only difference I can discover consists in the 
flower being a little larger, the filaments longer and the anthers shorter. 
^ BREVIAT A: lobes of calyx more membranaceous, less deeply divided, scarcely imbricate, rather longer 
than the short funnel-shaped tube of the corolla ; lacinise as long as tube ; styles as long as the conic ovary, shorter than

or almost sessile, in small compact clusters ; lobes of calyx and corolla broadly triangular, acute, the latter 
often somewhat crenulate ; scales usually small, ovate or spatulate, attached to the middle of the tube and scarcely 
reaching to the throat; styles capillary, usually much shorter than the conic ovary; stigmas rather small but very 
distinctly capitate, so that it is difficult to understand how Choisy could place this species among those with filiform 
stigmas ; even his own figure, though not quite correct, does not bear him out. - Capsule oval, 1-seeded, enveloped in 
the corolla, with top naked ; seed 0.6 line long, compressed obovate, rostrate, rough, with a very small hilum reduced 
to almost a point. This is Choisy’s original plant, from Coquimbo ; all the other specimens cited above belong to 
Var. /3. latiflora : flowers rather larger, 1^1 J lines long, petals spreading, scales often larger, styles longer; fruit 
not seen. Some of Pceppig’s plants approach the original specimens by their small flowers and crenulate lacinise. 
* * Flowers pedicelled, disposed in rather loose paniculate cymes, which often at last become crowded ; withered 
corolla usually enveloping the capsule or covering its top, in the three last species investing only its base,
