704 LXX. UMBELLIFER^. (C. B. Clarke.) [Pleurospermum. 



serrated somewhat closely and regularly. Bracts 5-8, 1-lf in., narrowly-lanceolate, 

 entire, white-margined; rays 10-20, 1-4 in.; pedicels in fruit ^-~| in., often exceeding 

 the bracteoles. Kidges of the carpels thin, narrowly winged, lateral rather the 

 broadest. The fruit is dorsally compressed ; Klotzsch's figure must have been 

 taken from very immature fruit, and does not show correctly the shape of the carpel 

 in horizontal section at any period. 



7. P. dentatum, Benth. in Gen. PL i. 915 ; leaves 2-pinnate pinnae -2 in. 

 ovate, bracteoles 5-8 in. lanceolate entire or minutely denticulate near the 

 apex, fruit \ in. ellipsoid. Ligusticum dentatum, Wall. Cat. 547. Hymenolsena 

 dentata, DC. Prodr. iv. 245. 



From KUMAON toSiKKiM, alt. 9000-13,000 ft., Wallich, &c. 



Stem 2-4 ft. Segments of the pinna % in., oblong or ovate, serrate. Bracts 

 3-0, 1 in., lanceolate, white-margined; rays 5-15, 1-3 in.; bracteoles usually un- 

 dulate on the margin, crenulate or denticulate, or quite entire ; pedicels in fruit 

 usually shorter than the bracteoles. Carpels elliptic, dorsally compressed ; ridges 

 thin, narrowly alate, lateral broadest; dorsal furrows 1-vittate, lateral 2-vittate ; 

 commissure plane, 4-vittate ; calyx-teeth ; style-bases not prominent. Seed very 

 obscurely concave on the inner face, or plane. Cnidium cuneatum, Ledeb. Fl. Alt. i. 

 331 ( Aulacospermum, Ic. FL Boss. iv. 7, t. 312) appears the same, but the authentic 

 example is in young flower only. It is said to differ by the upper branches and leaves 

 being opposite and whorled : but this is occasionally seen in many species of Pleu- 

 rospermum. P. dentatum, in the absence of fruit, is very difficult to distinguish from 

 P. angelicoides ; but the leaves and leaflets are generally smaller, the bracteoles lan- 

 ceolate (rather than narrow-lanceolate) and slightly crenulate or serrulate. In de- 

 fining the area of the species ; all Sir J. D. Broker's examples distributed as P. ange- 

 licoides have been referred to P. dentatum ; though the leaflets are large, the fruit 

 is small, and the bracteoles distinctly serrulate. 



VAR. erosa, DC. 1. c. ; bracts 4-5, leaflets more irregularly incise-serrate. 

 Mixed with the type as DC. states. There appear two states of the bracts, and 

 two very differently cut leaves ; the latter may indicate a different species as DC. 

 suggests, but the typical P. dentatum has sometimes many bracts. 



8. P. pumilum, Benth. in Gen. PL i. 915 ; leaves pinnate pinnas -1 in. 

 ovate lobed or subpinnatifid, bracts 1-2 small linear or 0, bracteoles 3-7 | in. 

 linear entire obscurely white-margined. Ligusticum pumilum, Wall. Cat. 550. 

 Hymenolsena pumila, DC. Prodr. iv. 245. 



NIPAL; Wallich. SIKKIM; Islumbo, alt 11,000 ft., C. B. Clarke. 



The specimens are without fruit. The species is very near P. dentatum, and differs 

 only in the subobsolete bracts and very narrow bracteoles. The Sikkim example 

 must have been at least 3 feet high, so that the name pumilum is not well applied to 

 the species. 



9. P. stylosum, C. B. Clarke^ leaves 2-pinnate pinnae 1-3 in. often 

 pinnatifid, bracteoles 6-10 lanceolate entire or incise-serrate at the apex, fruit 

 in. subglobose transversely plicate-rugose. 



KASHMIR; Falconer. LAHTJL; alt. 11,000-12,000 ft., Eev. H. Jaeschke. 



Stem 2-4 ft. Segments of the secondary pinnae -1 in., pinuatifid or serrate. 

 Bracts 4-6, 1-3 in., lobed or pinnatifid at the apex; rays 10-35, 1^-3 in. ; bracteoles 

 white-margined, entire, incised or lobed in the same umbel. Fruit slightly longer 

 than broad ; epicarp of very lax tissue (as in P. Govanianum) the transverse folds 

 occupying the whole back except the ridges ; style-bases prominent even on the ripe 

 fruit ; calyx-teeth obsolete ; ridges subequal, hardly winged. 



10. P. stellatum, Benth. in Gen. PL i. 915 ; leaves 1-2-pinnate pinnae 

 \ in. serrate or pinnatifid with small narrowly lanceolate lobes, bracteoles 5-8
