Bound, p. 114, excl. syn. P. cyananth.) Spithamgeus ad sesquipedalem ; 

 foliis radicalibus spathulatis, caulinis lanceolatis oblongis ovato-lanceo- 

 latis vel prgesertim superioribus subcordatis rigidis lajte glaucis ; thyrso 

 eloncato floribundo ; sepalis aut ovatis aut lanceolatis corolla 6-10 lin. 

 lonf^a ; capsula acutissime acuminata. — Saskatchawan and interior of 

 Oregon, along the mountains and elevated plains to Chihuahua. (No. 

 576, Fendler; 245 and 463, Wislizenus ; 1473, Wright ; 258, Parry, 

 a form nearly similar to P. secundijiorus, Benth. ; 264, Parry, and 

 390, Hall and Harbour, passing to P. ccBruleus.) Lindley, in pub- 

 lishing P. acuminatiis, describes the sterile filament as slightly hairy 

 and hooked at the point, but figures the tip dilated. So I find the tip 

 dilated and more or less yellow-bearded in the only flowering specimens 

 I have from the interior of Oregon, collected by Mr. Spalding. Ben- 

 tham's character, "filamento sterili filiformi glabro," which has been 

 misleading, I have verified only in Hall and Harbour's no. 385, 

 which in other respects is just P. secundijiorus. There is no question 

 about the propriety of reducing all these synonymes to P. acuminatus. 



^_ H_ Grandijlori ; corollis sesquipollicaribus speciosissimis; foliis cau- 

 linis prEEsertim superioribus rotundatis amplexicaulibus vel connato- 

 perfoliatis ; sepalis baud acuminatis ; filamento sterili apice adunco 

 leviter dilatato : cymiulis 2 - 5-floris absque pedunculo communi. 



16. P. GRANDIFLORUS, Nutt. {P. Bradburii,V\\vii[\.) Tripedalis ; 

 foliis omnibus distinctis ; pedicellis abbreviatis ; corolla subito inflata 

 C£esio-ca3rulea ; filamento sterili apice vix barbulato. — Wisconsin and 

 Iowa to Kansas. A very handsome species in cultivation, and the 

 earliest to flower. It is singular that it has not yet been figured. I 

 have never observed the sterile filament bearing a small two-lobed an- 

 ther, as Nees records in Prince Neu-Wied's Travels; on the contrary, 

 in the plants now for many years cultivated in the Cambridge Bo- 

 tanic Garden, this filament is absolutely wanting in about one blos- 

 som out of twenty. 



17. P. MuRRAYANUS, Hook. Bot. Mag. t. 3472. Bi - tripedalis ; foliis 

 superioribus floralibusque in laminam orbiculatam connatis ; pedicellis 

 gracilibus ; corolla sursum modice sensim ampliata l^te rubra ; fila- 

 mento sterili glaberrimo. — E. Texas (coll. IT. 292, Drummond ; 282, 

 Lindheimer, &c.) and Arkansas. In Mr. Durand's herbarium is a 

 specimen of P. Murrayanus from T. J. Hale of Wisconsin, said to 

 have been found at Dubuque, Iowa (where Dr. Hor collects P. grandi- 

 jiorus) ; but I suspect there is some mistake about it.
