22 BOTANY. 
pinnitifidis, lobis utrinque 5-8 obovatis obtusis integris vel 1-2-dentatis, petiolis basi nudis ; 
ramis simplicibus 8—12 floris pedicillis brevibus calycis lacemis spathulatis, corolle tuba infun- 
dibuliformis calyce subduplo longiore; limbo patulo placentis 8-ovulatis. Yampai valley; 
March 26. This was collected by Colonel Frémont in his journey to California in 1843~ 44, 
probably in the interior of that State, or in Western New Mexico. It is nearly allied to the 
Jast species, but differs in the much larger flowers, the corolla of which is purple, with the 
lower part of the tube yellow and much exceeding the calyx. The appendages of the tube are 
also dilated in the middle. The seeds are strongly corrugated transversely. 
PHACELIA (COREANTHUS) ARETIOIDES, Hook. & Arn. Bot. Beech., p. 314; Hook. Ic. t. 355.  Al- 
luvial bottoms of the Little Colorado; May 9. Camp 88. The specimens are in the earliest 
flowering state, corresponding with the var. PpeRPUSILLA, Hook. & Arn. I. c.

March 25. Eucrypta, Nuttall, Pl. Gamb., p. 158, seems io be hardly distinct from this genus, 
but it has fewer seeds.

grosse tridentatis, basi longe liniari cuneatis margine pinnato-setosis inherdium utrinque uni- 
dentatis dentibus apice setiferis ; capitulis paucifloris ; corolla tuba calyce longiore ; staminibus 
exsertis ; ovarii loculis 8-10 ovulibis. Rocky hill-sides, Camp 67; April 3. This well-marked 
species (which is nearly related to N. Schottii) was first collected by Colonel Frémont in 1844, 
near the Rio Virgen, towards the great Californian desert, and again in 1848. 
GILIA DACTYLOPHYLLUM, (n. sp.?) Mouth of Diamond river; April 3. The specimens are 
scarcely sufficient for description. A slender plant, about 3 inches high. Corolla twice as 
long as the calyx, white ; ovules about 7 in each cell.
