321. AspiDiUM . A fern of more delicate text- 

 ure than the preceding number, not well in fruit. 



3. Ihree Neio Species. 



HoRKELiA Kelloggii. Stems stout, ascending or nearly 

 prostrate, a foot long or more, from a thick ligneous, very 

 branching caudex : leaves of 5 — 7 pairs of obovate, coarsely 

 and rather deeply toothed leaflets: calyx-tube cupuliform, a 

 line deep and 2 J lines broad; segments lanceolate, about 

 3 lines long, fully equalled by the oblong bracteoles : petals 

 3 lines long, spatulate-oblong, clear white: the subulate 

 filaments also white, the 5 opposite the petals perceptibly 

 shorter than the other 5. — H. (Jalifoniica, var. sericea, Gray, 

 Proc. Am. Acad. vi. 529; Bot. Cal. i. 181. 



Most distinct from H. Califormca in habit as well as in 

 the color of the flowers and the very dissimilar proportions 

 of tube and limb of the calyx. In that species the tube is 

 not barely campanulate (much farther from cupuliform), it 

 is even somewhat urceolate, and nearly equal to the limb 

 itself in length. The peculiar pubescence of the present 

 plant is a good character, and the only one heretofore men- 

 tioned by authors. The species is apparently very local, 

 being now confined, in so far as I can discover, to two or 

 three town lots, which still remain unoccupied, in the west- 

 ern part of Alameda, hence it is destined to an early extinc- 

 tion, unless some new locality can be discovered for it. The 

 lots in which it is now growing are of a sand}^ soil and form 

 part of a bluff little elevated above the beach. H. Cali- 

 formca is a common plant of the wooded hills on both sides 

 of the Bay of San Francisco. The plant was originally dis- 

 covered by the late Dr. Albert Kellogg, and may appropri- 

 ately be dedicated to him who has so lately passed from 

 among us. 



HoRKELiA Parryi. Caesj^itose, the slender stems 6 — 10 

 inches high: herbage green, and with a sparse soft pubes- 

 cence and some glands about the inflorescence: leaflets
