 For fear that this purely artificial key may not be found 

 to apply with all garden plants, which are so mucli more 

 liable to variation, there is given below a key based on 

 more technical characters, derived from Gray's Synoii- 

 tical Flora: 



BOTANIST'S KEY. 



1. Section Euphacelia. Ovules 4, a pair to each 

 placenta; seeds generally fewer, with reticulate or pit- 

 ted testa: corolla-tube with 10 laminate appendages in 

 pairs at the base of the stamens.

12. Orcuttiana 



1. hdmiliB, Gray. Annual, unbranched or branched 

 from the base, 2-6 in. high, pubescent or inflorescence 

 often hirsute: Ivs. spatulate oblong or oblanceolate, 

 generally obtuse, the lower rarely with 1-2 ascending

1732. Phacelia viscida 



lolies : spikes loosely paniculate or solitary : corolla 

 indif^o-bhie. rather deeply lobed, surpassing the usually 

 lim-nr o;ilyx-lobes; filaments moderately exserted, gla- 

 lirous or sparingly bearded above. Calif, to Wash. — This 

 pn-tty little plant seems to be unknown to the trade, but 

 it is to be hoped it will not so remain. 



2. glanduldsa, Nutt. (Futbca glanduldsa. Hook.). 

 Viscid-pubescent and glandular, softly if at all hirsute, 

 9-12 in. or more high: Ivs. irregularly and interruptedly 

 2-pinniitifid, or below divided; the numerous lobes ob- 

 long, small, somewhat incised, obtuse: calyx -lobes 

 oblong or spatulate: corolla about 2 lines long, bluish, 

 purplish or white, with lobes shorter than the tube; 

 stamens and 2-cleft style moderately or conspicuously 

 exscrtiMl : seeds with the minute reticulations even.

oval, iiicisely pinnatifid or irregularly lobed, the lower 

 lines niiistly" petiolate and the upper confluent; calyx- 

 liilies linear or somewhat spatulate; corolla blue, 3 lines 

 long, the lobes as long as the tube; stamens more or 

 less exserted : seeds reticulate scabrous, the fine sharp 

 meshes being, as it were, toothed at the junctions. Tex.
