Scrophularineai.] CALIFORNIA— SUPPLEMENT. 379 



4. O. eriardhus {Benth.) ; basi pubescens apice tomentosus ramosissimus, foliis apicc 

 multifidis laciniis lineari-setaceis divaricatis, calycibus tomentosis dentibus lanceolatis 

 acutissimis viridibus, corollae (luteae) tubo longe exserto tomentoso, antheris galea bievi- 

 oribus. Benth. I. c. 



The upper lip of the corolla is purple and subulate ; the lower exhibits the same structure we have ob- 

 served in O. gracilis, but it is wider, the lateral lobes being more divaricated. 



5. O. densiflorus {Benth.); glabriusculus ramosissimus, foliis apice trifidis laciniis 

 linearibus, spicis densis imbricatis (flavescentibus), laciniis calycinis lineari-subulatis 

 subcoloratis corollae pubescentis tubum aequantibus, staminibus galea brevioribus. Benth. 

 1. c. p. 13. — Castilleja ambigua. Hook, et Am. supra, p. 154. 



The lower lip of the corolla has three subulate processes or teeth at the apex ; it is 3-lobcd, the lobes 

 concave and slightly saccate, thus intermediate between the structure of Triphysa and the true Orthocarpi. 



6. O. purpurascens {Benth.); ramosissimus piloso-hirtus, foliis pinnato-multifidis laciniis 

 linearibus divaricatis, spicis densis imbricatis (purpurascentibus), laciniis calycinis brac- 

 tearumque lineari-spathulatis apice coloratis corollae pubescentis tubum aequantibus. 

 Benth. I. c. 



Lower lip sharply S-toothed at the apex, the lateral lobes slightly concave, the middle one saccate near the 

 apex. 



7. O. Tolmiei; puberulus, caule stricto (saspius e basi) ramoso, foliis lineari-acuminatis 

 integris, floribus breviter spicatis, bracteis divaricato-trifidis corollam superantibus laciniis 

 linearibus, dentibus calycinis lanceolatis acuminatis tubo membranaceo subduplo breviori- 

 bus viridibus, corolla (lutea) glabra, tubo longe exserto, labio superiore apice uncinato 

 inferiorem trilobum erectum adpressum paullo superante. 



Hab. Between Henry's and Smith's Rivers, Snake Country. Mr Tolmie. 



This is so closely allied to O. strictus that we at first proposed to unite it as a variety. The leaves, how- 

 ever, are always entire and narrower, the spikes shorter, the whole plant smaller and rather pubcru.ous than 

 'hispid, the calyx-lobes longer, and the upper lip of the corolla narrower and hooked at the apex, and slightly 

 longer than the lower. Like it, the flowers are yellow, the tube of the calyx membranaceous, and the lower 

 lip erect and close pressed to the upper, as in Melampyrum. 



8. O. lithospermoides {Benth.); erectus durus ramosus basi pubescens apice hispidus, 

 foliis trinerviis apice inferioribus integris superioribus 3-5-fidis laciniis lanceolatis, spicis 

 densis flavescentibus hispidis, dentibus calycinis lanceolato-linearibus flavescentibus his- 

 pidis tubo corollae glabriusculo brevioribus. Benth. I. c. 



The lower lip of the corolla has precisely the structure of that of O. erianthus. 



9. O.castillejoides {Benth.); humilis pilosiusculus, foliis oblongis superioribus cuneatis 

 breviter trifidis, floribus laxe spicatis, calycibus tubulosis dentibus brevibus viridibus, 

 corollas (purpurascentis) tubo breviter exserto. Benth. I. c. 



This we have not seen.
