4. O. erianthus {^Benth.) ; basi pubescens apice tomentosus ramosissimus, foliis apice 
multifidis laciniis lineari-setaceis divaricatis, calycibus tomentosis dentibus lanceolatis 
acutissitnis viridibus, corollas (luteae) tubo longe exserto totnentoso, antheris galea brevi- 
oribus. Benth. 1. 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 corollas pubescentis tubum aequantibus, staminibus galea brevioribus. Benth. 
1. c. p. 13. — Castilleja ambigua. Hook, et Arn, supra, p. 154. 
The lower lip of the corolla has three subulate processes or teeth at the apex ; it is 3-lobed, 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 corollse pubescentis tubum tequantibus. 
Benth. 1. c. 
Lower lip sharply 3-toothed at the apex, the lateral lobes slightly concave, the middle one saccate near the 
apex. 
7. O. Tolmiei; puberulus, caule stricto (saepius 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. Eetween 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 puberulous 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 flow'ers 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. 1. 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, 1. c. 
This we have not seen.
