CALIFORNIA.— SUPPLEMENT. 



[Hydrophyllea. 



This is a very remarkable species, having bright yellow flowers. The seeds are deeply wrinkled on the 

 back. It differs from Eutoca by the persistent but marcescent corolla ; and from Emmenanthe by its habit 

 and absence of scales to the corolla.

 funde 5-partiti laciniis anguste linearibus hispidis tubo corollas infundibuliformis (pur- 

 purea;) duplo brevioribus, ovario multiovulato — var. (3. perpusilla; caule subnullo pauci-

This beautiful species will probably yet be separated from Eutoca, to which it bears no external resem- 

 blance ; but we have placed it here as agreeing almost entirely with Bentham's character of the genus. 



PHACELIA. Juss. Benth. I. c. 



Corolla decidua. Ovarium ovoideo-globosum, piloso-hispidum. Placenta lineares, ssepius dorso parietibus 

 ovarii adnatse, 2-ovulatae. Capsula dissepimentis subcompletis pseudo-bilocularis. — Herbas annum vel 

 perennes, erectce vel diffuses. Flores racemosi, densi, sessiles vel laxi pedunculati, cymis unilateralibus

Mr Bentham adduces the following synonyms to this species : — Heliotropium pinnatum, Vahl. — Hydro- 

 phyllum Magellanicum, Lam. ; H. Aldea, Rcem. et Schult. — Aldea pinnata, Ruiz et Pav. ; A. circinnata, 

 Willd. — Phacelia Peruviana, Spreng. ; P. Californica, Cham. ; P. heterophylla, Pursh ; P.rudis, Dougl. 



2. P. ciliata {Benth.); scabro-pubescens, foliis pinnatisectis, segmentis oblongis obtusis 

 subpinnatifidis, calycis laciniis ovatis submembranaceis reticulatis margine ciliatis, stamini- 

 bus corollam subaequantibus. Benth. 1. c. p. 280. 



3. P. ramosissima [Dougl.) ; scabro-pubescens vel hispida, foliis pinnatisectis, segmentis 

 ovatis obtusis subpinnatifidis, calycis laciniis oblongis viridibus hispidis fructiferis spa- 

 thulatis, staminibus exsertis. Benth. I. c. p. 280. 



We have an allied species, or perhaps a mere variety, from Dr Gillies, under the name of P. Brunoniana, 

 collected on El Cerro del Diamante and Andes of Mendoza, and it only differs by being more covered with 

 glutinous hairs, and having a nearly simple stem. 



4. P. tanacetifolia (Benth.); scabro-pubescens vel hispida, foliis bipinnatifidis, segmentis 

 oblongis dentato-pinnatifidis, calycis laciniis oblongo-linearibus hispidis, staminibus 

 exsertis. Benth. 1. c. Lindl. in Bot. Reg. t. 1696. 



A closely allied species has been sent us by Mr Darwin, who found it at Bahia Blanca, on the coast of 

 Patagonia (No. 202), but the hairs on its stem are all glutinous.
