Bakiclii&tan. Dry and arid districts of 

 North Western India on both sides of the 

 Indus, north as far as Lahore, and east to 

 Bikanir. Abundant and often gregarious. 

 The young shoots come out Febr.-March, soon 

 afterwards the shrub is covered with pinkish 

 fi.j filling the air with a strong pleasant odour. 

 Fr. June. The fl. are swept up and eaten, 

 cooked. I adhere to the view" of my old Forest 

 Flora, p. 372, that C. comosum is not distinct. 

 Accordingly this species has a wide distribu- 

 tion outside India from Algeria to Afghanis- 

 tan. 



Pteropyrum Olivieri, Jaub. et Spach, Sind, 

 Baluchistan, Persia. A rigid much branched 

 shrub, 1. fascicled, thick, glaucous, from spathu- 

 late to linear, nerveless, J-| in. long. Fl. small, 

 in many-fid. clusters, sepals 5, in fruit not 

 much enlarged, the inner erect and appressed 

 to the nut, alternating wdth its wings, the 2 

 outer reflexed. Nut wdth 6 broad wings in 

 two tiers, thos3 of the lower tier larger. P. 

 Aucheri, Jaub. et Spach, Northern Baluchistan 

 (Aitchison) Western Asia, supposed to be dis- 

 tinguished by narrow linear 1., probably is not 

 distinct. 



Rumex hastatus, Don ; Collefct Simla Fl. 428 

 fig. 136. Vern. Khatimhal, Haz. Outer ranges 

 of the North West Himalaya, mostly on dry 

 slopes ascending to 8,000 ft. Afghanistan. An 

 undershrub with a stout woody rootstalk, 

 sometimes a shrub, branches numerous, slender. 

 L. triangular or hastately 3-lobed, the lobes 

 narrow, almost linear, blade J-IJ in. long. pet. 

 as long as or longer than blade. Fruiting sepals 

 orbicular, pink, prominently net-veined.

Oeder LXXXVIII. ARISTOLOCHIACE^. Gen. PI. iii. 121. 



Herbs or shrubs, often climbing, 1. alternate, entire or 3--5-lobed, stipules 0. 

 Fl. bisexual, often large. Perianth superior, regular or zygomorphic, 3-lobed 

 or tubular. Stamens 6 or more, free, or anthers sessile in a ring on the stylar 

 column, cells parallel, opening by dorsal slits. Ovary inferior, 4:-6-celled, 

 placentas parietal, ovules numerous, style columnar. 'Ft. capsular or baccate, 

 seeds numerous, embryo minute in a copious, fleshy albumen. 



Oil cells in the parenchyma of leaves and outer bark are common in most species. 

 The wood is very porous, the structure is usually normal with broad medullary rays 

 and large vessels, the wood fibres have bordered pits. The radial wedge-shaped masses 

 of wood often appear bifurcated by the formation of broad second, med. rays. The 

 wood of Braga7it%a is peculiar, cf . Gamble Ind. Timbers, ed. ii. 553 ; Masters in Journ. 

 Linn. Soc. xiv. 487.

Engler u. Prantl iii. 1. 272); 



Slirubs or underslii^ubs, 1. entire, 3 or 5 basal nerves, tertiary nerves and 

 reticulate veins conspicuous beneath. Perianth shortly campanulate, 3-lobed. 

 Stamens 6-12, 1-seriate, filaments short, connective thick. Ovary elongate,
