Oarkia (Onagraceae) — known as godetia or farewell-to-spring — 

 have shown that several "species" that have long been recognized 

 are in fact each composed of more than one species. As a result 

 of these studies, a number of new species have been described in 

 recent years. There are a few species of other genera in California 

 which have been collected for the first time in recent years. 

 Most of these have come from the North Coast Ranges or Kla- 

 math mountains, but recently a species of Limnanthes (meadow 

 foam, Limnanthaceae) was described from a series of conspicuous 

 populations just north of San Francisco Bay and in a fairly 

 densely populated area. Even more remarkable, a distinctive, 

 previously uncollected new species of the mariposa-lily genus 

 Calochortus (C. tiburonensis, Plate 2B) was recently discovered 

 on a hilltop on Tiburon peninsula, Marin County, where the 

 small population of the plant grows in full sight of the millions 

 of residents of the San Francisco Bay area! No one had collected 

 specimens of this plant until very recently, although there is 

 reason to believe the species has occurred in this heavily popu- 

 lated region for thousands of years. 



In many manuals that cover the California flora, the binomial 

 may be followed by a surname or an abbreviation of the surname 

 of the person who named the species. Examples are Astragalus 

 nutans Jones (for Marcus E. Jones) and Angelica tomentosa 

 Wats, (for Sereno Watson). Although these surnames are techni- 

 cally a part of the plant name, they are not a part of the binom- 

 ial and are not used in verbal communication, although in 

 botanical writing they are often used.
