at a time in the region where it grows, 

 it is naturally well adapted to survive 

 a long: continued drouth; it is one of 

 the most curious productions of the 

 plant world, forming a tree often over 

 SO or 40 feet high, resembling a great 

 carrot with its roots in the air. Dr. 

 Albert Kellogg named it Idria Colam- 

 naria; later it was recognized us be- 

 longing to the genus Fouquiera 

 Genus OROUTTIA Vnsey. 



"Panicle somewhat spicate, with short, 

 airnple, alternate, sessile spikelets, suim.- 

 v^hat distant below, and crowiLd toy/aid 

 the summit: spikelets many-il'd, com- 

 pressed: empty and* fl'ng glumes mvu-h 

 alike, with many prominent straight 

 nerves, strongly toothed or lobed at the 



; x; palet equalling its glume, i.a/ruw, 

 u-in, green on the strongly angled keels: 

 anthers 3, styles 2, nl and sty.es project- 

 ing beyond the apex." Vasey, bot gaz 18: 



OBCUTTZA CALIFORNICA Vase y. 



"Plant dwarf, 2-4 inches high, annual; 

 growing in small clusters of l^-2b or more 

 culms from one root; culms variable in 

 lergth in the same cluster, generally pro- 

 ducing some small flowering branches 

 from the lower joints; leaves 2 or 3. the 

 sheaths open and inflated, striate; ligule 

 obsolete; blade rather rigid, about 1 inch 

 long, acuminate; leaves and sheaths 

 sparsely pubescent; panicle about 1 inch 

 long, simple, usually of 4-6 al:. ornate ses- 

 sile spikelets, the lower 2 or 3 rather dis- 

 tant, the upper ones crowded; spikeleis 

 5-10 flowered, empty glumes sparsely pu- 

 bescent, broad, about 2 lines Ions, seari- 

 ous-margined, mostly 3 lobed. the 2 out^r 

 lobes longer, the lobes each 3-nerved;

 spikelets are clustered together at the 

 apex of the culm, with only 1 pair of 

 empty glumes for all. A dwarf grass 

 collected near Quintln, by C. R, Orcuu, 

 an ardent yctmg natvra'ist, for whom the 

 genus is named." Vasey, Torr cl b -i3:21
