Baluchistan. 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 

 fl., 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 V. 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— 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 with its wings, the 2 

 outer reflexed. Nut with 6 broad wings in 

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

 Aurlieri. Jaub. et Spach, Northern Baluchistan 

 (Aitchison) Western Asia, supposed to be dis- 

 tinguished by narrow linear 1., probably is not 

 distinct. 



Rumex hastatua, Don : Collett Simla Fl. 428

 of the North West Himalaya, mostly on dry 

 elopes 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-lj in. long. pet. 

 ,'i. Imii"; as i.i- lunger t ban blade. Fruiting sepals 

 orbicular, pink, prominently net-veined.

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 <> 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. Fr. capsular or baccate, 

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



Oil cells in the parenchyma of leaves and miter hark an- common iii must species. 



The w i 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 

 oi w I often appear bifurcated by the formation of broad second, med. rays. The
