1. Delphinium bicornutum, Hemsley, Diag. Pl. Nov. pars alt. p. 17. 
Foliis palmatim 5-partitis, segmentis latiusculis 3—5-lobatis, floribus circiter pollicaribus, calcari 
calycino basi distincte bicornuto fere recto sepalis longiore, calcaribus petalinis calcari calycino 
eequilongis basi tantum tubulosis, petalis lateralibus basi appendiculatis, carpellis 3 immaturis 
pubescentibus. 
Herba 2-3-pedalis, caulibus subsimplicibus crassiusculis, glabris, levibus. Folia (radicalia mihi 
ignota) caulina inferiora longe petiolata, palmatim 5-partita ; segmentis latiusculis, 1-14-poll. 
longis, 3-5-lobatis, subtus sparse puberulis, petiolo usque 6-pollicari. Pedunculi pauciflori, 
bracteis linearibus. Flores pollicares, puberuli, pedicellati, pedicellis puberulis bibracteolatis, 
bracteolis subulatis; sepala oblonga, acuta vel obtusa, calcari fere recto basi distincte bicornuto 
deorsum spectante; petalorum superiorum laminis angustis obliquis, apice rotundatis breviter 
bifidis, calcaribus calcari calycino equilongis basi tantum tubulosis; petala lateralia ungui- 
culata, alte bifida valde barbata, ungue basi appendice squamiformi ornato ; stamina leviter 
puberula. Carpella 3, immatura, puberula. 
Soutn Mexico, Oaxaca (Ghiesbreght). Hb. Kew. 
Characterized by the distinctly bifid, relatively long calyx-spur, the rather long basal 
appendage of the lateral petals, the short tubular portion of the spurs of the upper 
petals, &c. & 
2. Delphinium latisepalum, Hemsley, Diag. Pl. Nov. pars alt. p. 17. 
Foliis palmatim 5-partitis, segmentis latiusculis semel vel bis lobatis, bracteis linearibus, floribus 
subvillosis circiter pollicaribus, calcari calycino basi integro leviter curvato sursum spectante 
sepalis eequali vel breviore, calcaribus petalinis calcari calycino equilongis basi tantum tubu- 
losis, petalis lateralibus exappendiculatis, carpellis 3 immaturis pubescentibus. 
Herba sesquipedalis, plus minusve pubescens vel villosa, caulibus subsimplicibus. Folia palmatim 
5-partita, 14-3 poll. diametro; radicalia segmentis latiusculis, 3-5-lobatis, petiolo 2-3-pollicari ; 
caulina segmentis linearibus integris. Pedunculi pauciflori, pedicellis gracilibus. Flores 
villosi, circiter pollicares ; sepala late oblongo-elliptica, rotundata, calcari basi integro leviter 
curvato sursum spectante sepalis quali vel breviore; petalorum superiorum laminis angustis vix 
obliquis, apice brevissime bifidis, calcaribus calcari calycino eequilongis basi tantum tubulosis ; 
petala lateralia anguste unguiculata, basi exappendiculata, alte bifida, utrinque valde barbata ; 
stamina glabra. Carpella 3, immatura, cano-pubescentia. 
Sourn Mexico, Cordillera of Oaxaca, 8000 to 8500 feet (Galeotti, 4547). Hb. Kew. 
This differs from the other Mexican species described here in its relatively short up- 
turned calyx-spur, broad sepals, &c. 
3. Delphinium leptophyllum, Hemsley, Diag. Pl. Nov. pars alt. p. 18. 
Foliis alte palmatim 5-partitis, segmentis angustis alte trisectis, lobis ultimis linearibus, floribus
