Species novae generis Aconiti. 
(Originaldiagnosen.) 
18. Aconitum gracilentum Greene, nov. spec. 
Radices fusiformes 2—4, fasciculatae, subcarnosae, 2—3 cm longae, 
nigricantes; caulis unicus tenuis erectus strictus simplex glaber pur- 
purascens, 4—6 dm altus, supra medium laxe racemosus; folia parva, 
4-6 cm longa, profunde 5-partita, segmentis cuneatis, incisis; flores 
pauci (4— 6), vix mediocres, longissime pedunculati, caeruleo-purpurei; 
Sepala anteriora oblongo-linearia, obtusiuscula, sepalo posteriore galeato, 
sacco brevi obtuso, rostro subulato-lineari longo fere horizontali; folliculi 
breves oblongi sparsim hirsuti. 
A slender species, inhabiting mountain bogs in eastern Oregon, at 
altitudes of 6—7000 feet, a habitat most unlike that of the real A. Colum- 
bianum with which this has been confused. The present plant has been 
distributed by Mr. W. C. Cusick, under his no. 1798. The flowers are 
sometimes yellowish and merely tinged with purple. The specimens 
described are in my own herbarium. 
19. Aconitum Leibergii Greene, nov. spec. 
Radices binae, tenuiter fusiformes, 2-4 cm longae, sublignosae 
potius quam carnosae; caulis unicus erectus simplex teres gracilis, 
3—5 dm altus, inferne pilis brevibus arcte recurvis sparsim obsitus; 
folia parva, 2.5—4 cm diametentia, profunde 5-partita, segmentis late 
cuneiformibus 3—5-lobis, praecipue superiora sparsim et brevissime 
pubescentia; racemus simplex laxiusculus, 4—8-florus; flores pro planta 
magni, atrocyanei; sepala anteriora oblongo-linearia, sepalo posteriore 
valde elato et quasi in calear longuisculum obtusum incurvum producto, 
rostro subulato magno horizontaliter extenso; folliculi turgescentes glabri. 
A most elegant species known only as collected in the Klamath
