5. C. integerrimus ; glaber, ratnis subangulatis parce resinoso-viscosis, foliis 3-costatis 

 submembranaceis oblongo-ellipticis obtusis integerrimis subtus pallidioribus, paniculis 

 elongatis multifloris, floribus glomeratis albis. 



A very distinct species, with quite entire leaves, and very long narrow panicles of white flowers. Except 

 on the very youngest leaves or branches, there is no appearance of pubescence on the plant. Ovary without 

 projecting lobes. 



6. C. cuneatus ; ramulis teretibus pubescentibus, foliis penninerviis oppositis fascicu- 

 latis coriaceis oblongo-cuneiformibus integerrimis obtusis v. emarginatis supra glabris 

 subtus in areolis cano-pubescentibus, glomerulis densifloris brevibus subumbellatis, (flori- 

 bus albis) ovario grosse 3-tuberculato. — a. rufescens ; ramulis pubescenti-ferrugineis. — 

 Rhamnus? cuneatus. Hook. Fl. Bor. Am. I. p. 124. — Ceanothus macrocarpus. Nutt. in 



Torr. et Gr. Fl. 1. p. 267 (3. cinerascens ; ramulis cinereo-puberulis. — C. cuneatus. Nutt. 



in Torr. et Gr. Fl. 1. p. 267. 



We agree with Messrs Torrey and Gray in thinking that C. macrocarpus, Nutt. (which is certainly our 

 original Rhamnus f cuneatus), and the C. cuneatus, Nutt., constitute in reality but one species, differing as 

 they do almost exclusively in the colour of the pubescence. Both have the same balsamic odour. The authors 

 just mentioned are likewise disposed to consider the C. verrucosus of Nutt., in Torr. et Gr. 1. c.,as another 

 var. of C. cuneatus. 



7. C. rigidus ; ramulis teretibus pubescenti-tomentosis, foliis penninerviis oppositis 

 orbiculari-cuneatis retusis coriaceis grosse spinoso-dentatis supra glabris subtus in areolis 

 subincanis, glomerulis multifloris brevibus subumbellatis (floribus creruleis). — Nutt. in 

 Torr. et Gr. Fl. I. p. 268. 



8. C. dentatus ; fulvo-sericeo-pilosus, ramis teretibus, foliis alternis penninerviis fascicu- 

 latis coriaceis oblongo-cuneiformibus marginibus revolutis grosse glanduloso-dentatis 

 supra sparse subtus dense pubescenti-sericeis, pedunculis elongatis, paniculis oblongis 

 densifloris (floribus albis). — Torr. et Gr. Fl. \.p. 268. 



9. C. papillosus ; ramis teretibus hirto-tomentosis hie illic resinoso-verrucosis, foliis 

 densis oblongis coriaceis alternis penninerviis junioribus stipulaceis supra margineque 

 glanduloso-papillosis pubescentibus subtus tomentosis, pedunculis subaggregatis ad apices 

 ramulorum, floribus (caeruleis) capitatis deciduo-bracteatis, ovario lobulis tribus elongatis 

 erectis.— Torr. et Gr. Fl. 1. p. 268. Hook. Ic. PI. 3. t. 272. 



This species has a fragrant and somewhat resinous smell. 



Ord. XVII. LEGUMINOSM. Juss. 

 1. Thermopsis macrophylla ,• caule angulato, petiolis calycibus ovariisque hirsutissimis, 

 foliis trifoliolatis, foliolis obovato-ellipticis utrinque acutis supra glabris subtus pubes- 

 centibus, stipulis maximis (biuncialibus) ovatis acutis. 



Leaflets 4 inches long. Calyx angled, deeply 2-lipped ; upper lip ovate bidentate, lower 3-partite, the 

 segments laneeolato-subulate. Stamens 10, free. Ovary linear, densely sericeo-villous, on a short glabrous 

 stipes. A very fine and distinct species, with apparently white, but probably, when recent, yellowish flowers. 

 Leaves much longer than in any hitherto known species.
