* * Nutlets all four or all but one scarious-winged at the margins, attached for their 
whole length: spikes bractless. 
8. K. pterocarya Gray. Slender, loosely branching, hirsute: leaves linear, or 
lowest spatulate, often hispid: inflorescence at first cymose-glomerate, usually de- 
veloping a pair of short spikes: calyx-lobes erect: corolla very small: nutlets rough 
on the rounded back, one commonly wingless and rounded on the sides, the others 
with lateral angles extended into a broad radiately striate wing with toothed or 
crenulate margins. (Eritrichium plerocaryum Torr,)—Western borders of Texas. 
« * * * Nutlets acutely triangular, wingless, attached for most of their length to a subu- 
late qynobase. 
9, K.JamesiiGray. Rather stout, branched froma woody base, canescently silky- 
tomentose, becoming strigose-hirsute or even hispid in age: leaves oblanceolate or 
upper-linear: spikes panicled or crowded, bracteate: corolla with prominent crests 
at throat: fruiting calyx neatly closing over the depressed-globular fruit, which 
consists of 4 closely-fitting very smooth and shining nutlets (which are almost exact 
quarters of asphere), (Hritrichium Jamesii Torr. )—Plains and sandy shores, western 
borders of Texas. 
8. MYOSOTIS L. (FoRGET-ME-NOT, SCORPION-GRASS. ) 
Low and mostly soft-hairy herbs, with entire leaves, small flowers in 
naked racemes, salverform corolla with tube about as long as the 5- 
toothed or 5-cleft calyx and throat with 5 small and blunt arching ap- 
pendages opposite the rounded lobes, included stamens on very short 
filaments, and smooth compressed nutlets fixed at base. 
1. M. verna Nutt. Bristly-hirsute, branched from base, erect: leaves obtuse, 
linear-oblong, or lower spatulate-oblong: racemes leafy at hase: corolla very small, 
white: pedicels in fruit erect and appressed at the base, rather shorter than the 
deeply 5-cleft unequal very hispid calyx.—-Dry ground, extending from the Atlantic 
region into Texas, where also occurs var. MACROSPERMA Chapm., which is taller, 
with more spreading pedicels, larger flowers, and larger nutlets. 
9. LITHOSPERMUM Tourn. (GROMWELL, PUCCOON.) 
Herbs, with thickish and commonly red roots, sessile leaves, solitary 
(as if axillary) or spiked and leaty-bracted flowers, funnelform or 
salverform corolla with throat (in ours) with more or less evident ap- 
pendages, almost sessile included anthers, and ovate smooth or rough- 
ened mostly bony or stony nutlets fixed by the base. 
* Nullets brownish and uneven, coarsely pitted (at length shining) : corolla white or whitish, 
litile longer than calyx. 
1. L. Matamorense DC. Hirsute or hispid: stems much branched from base, 
diffusely spreading, slender: leaves oblong, very obtuse: pedicels very short: corolla 
4 mm. long.—Plains and river-banks of southern Texas, 
** Nutlets white, smooth and shining: corolla large, salverform or nearly 8o, yellow, 
somewhat pubescent, the tube much exceeding the calyx. 
+ Corolla-tube half to twice longer than calyx, with appendages little if at all projecting: 
lobes entire. 
2. L.-multiflorum Torr. Minutely strigose-hispid: leaves linear or linear-lance- 
olate: flowers numerous, short-pediceled, the latter spicate: corolla light yellow, 
narrow, 10 to 12 mm. long, with very short rounded lobes and tube fully twice the 
length of the calyx, sparingly bearded at base inside.— Western Texas,
