4 DARLl.NGTOM.V CALIFORMCA. 



Bentliaiu ; and a Calitbniiaii plant, on inijierfect specimens of which, I had recently 

 indicated a genus under this name, proves to be only a species of Styrax.* The 

 following are the characters of the new genus : — 



DARLINGTONIA, -Nov. Gen. 



Calyx ebracteolatus, 5-sepalus ; sepalis distinctis subpetaloideis. Corolla 5-sepala; 

 petalis latissime unguiculatis ; lamina ovata ungue multo minore. Stamina 12-15, 

 uniserialia ; filanientis brevibus subulatis ; antheris oblongo-linearibus ; loculis inaj- 

 qualibus. Ovarium turbinatum, 5-locuIare, 5-lobatum ; apice dilatatum concavum. 

 Stylus brcvis, columnaris, 5-fklus ; laciniis linearibus, divergentibus, apice intus 

 stigmatosis. Ovula plurima anatropa, placentas dilatatas obtegens. Capsula . . . 

 — Herba perennis, Californica, uliginosa, foliis Sarraceniae ; lamina profunde 

 biloba ; lobis divergentibus : scapis unifloris, bracteatis ; bracteis infimis distan- 

 tibus, supremis approximatis imbricatis : flore nutante purpureo. 



* Having recently obtained good flowering specimens of this plant, the following 

 description of it is appended : — 



Styrax Californicum (?;. sp.) : foliis ovatis utrinque obtusis subcoriaceis iutegerrimis 

 ramulisque glabriusculis vel subtus minute stellato-tomentosis ; racemis terminalibus 2-4- 

 floris ; pedicellis flore multo brevioribus incrassatis cum calyce brevissime 6-dentato sub- 

 tomentosis ; corollis sexpartitis ; filamentis ad medium usque monadelphis. 



Hab. — Upper Sacramento : Col. Fremont. Near the upper crossing of the Sacramento, 

 about lat. 40° 30' : Dr. G. W. Hulse. Foot-hills of the Yuba Eiver : Dr. Stillman. Flowers 

 in March and April. 



An upright branching shrub, seldom attaining a height of more than six feet. The leaves 

 vary from an inch to two and a half inches in length, and are more or less broadly ovate in 

 outline. The under surface is paler, and either nearly glabrous or clothed with a close 

 stellate pubescence ; on the upper side they are usually quite smooth. The racemes are 

 pj'oduced at the extremity of short leafy branches, and are mostly about three-flowered ; 

 occasionally the flowers are solitary. The pedicels are from three to six lines long, and are 

 thickened upward. The campanulate calyx is furnished with six very short subulate teeth. 

 Corolla about three fourths of an inch long, nearly white, or slightly cream-color ; constantly 

 6-parted, with oblong-lauceolate rather obtuse segments. Stamens 10-14 ; the filaments 

 monadelphous to near the middle. Ovary 3-celled, with several ovules in each cell ; but the 

 dissepiments soon separate from the walls. Style slender, longer than the stamens ; stigma 

 minutely 3-cleft, Immature fruit one-celled, with a single seed. 



Of the numerous American species of Styrax only two have been found on the west side 

 of the Continent, as far north as Mexico. This is the most northern species of the genus 

 found in any part of the world. It has a strong resemblance to S. officinale of Southern 

 Europe, from which it is chiefly distinguished by its fewer-flowered racemes, thickened 

 pedicels, and longer stamineal tube. There is a well-marked, unpublished species (S. PLATIXI- 

 FOLIUM, Enrjehn. ined., gathered on the Guadaloupe, north of New Braunfels, Texas, by Mr. 

 Lindheimer), the corolla of which is more commonly 6-parted. Its dilated and subcordate 

 leaves are glabrous and shining on both sides.
