Boehmeria.'] cxxxvi. URTICACE.E. (J. D. Hooker.) 579 



Var. rotundifolia, Wedd. I. c. 212; leaves broadly elliptic ovate or rounded 

 cuspidately caudate tail often long and broad tomenfcose pubescent hispid or smootb, 

 tpeth usually very large sometimes confined to the upper part. B. rotundifolia, Don 

 Prodr, 60. B. caudigera, Wedd. I. c. 199 ; Blume I. c. 219. Urtica caudigera, 

 Wall. Cat. 4585. U. blanda, Wall. mss. Himalaya, Khasia, the Concan, Ceylon. 

 Clarke (Jouru. Linn. Soc. Bot. xv. 125)- regards this as a very distinct species. 



Var. canescens, Wedd. 1. c. 213 ; leaves membranous hoary serrated to the base 

 green when dry. B. canescens, Wedd. 1. c. 200 ; Blume 1. c. 224. B. ternifolia, 

 Don Prodr. 59. Urtica macrostachya, var. canescens, Wall. Cat. 4582 D. Kurnaon, 

 Nepal (" Herb. Madr." in Wall. Herb, is probably an error). 



Var. cinerascens ; stem slender flaccid hoary and with long spreading hairs, 

 loaves membranous ovate toothed to the base, spikes short simple slender. Urtica 

 cinerascens, Wall. Cat. 4591. Nepal, Wallich. Duphla Hills, Booth. Probably 

 a shade-loving form passing into U. Ramiltoniana, but the teeth are larger. 



Var. longissima ; glabrous, leaves ovate or elliptic-oblong coarsely crenate- 

 toothed base acute rounded or subcordate, petiole 3-6 in., spikes 12-18 in. extremely 

 slender, fl. clusters very small .hispid, beak of fruit long, style short. Pulney Mts., 

 Wight (Kew Distrib. 2707). Nilghiris, Gardner. Ceylon, Walker. 



9. B. Hamiltoniana, Wedd. in Ann. Sc. Nat. Ser. 4, i.199; Monogr. 

 371 ; branches slender glabrous, leaves opposite membranous long-petioled 

 lanceolate or oblong-lanceolate finely acuminate crenulate or serrulate or 

 subentire, base acute or obtuse, petioles of opposite pairs usually very 

 unequal, spikes simple very slender, fl. clusters small, styles shorter than 

 or equalling the minute fruit. Kurz For. Fl. ii. 424; Clarice in Journ. 

 Linn. Soc. Bot. xv. 124. B. platyphylla, var. Hamiltoniana, Wedd. in DC. 

 Prodr. xvi. i. 213. Urtica Hamiltoniana, Watt. Cat. 4590 A, B ?

 HILLS. Pegu and Martaban, Kurz. 



Differs from the more flaccid green states of B. platyphylla in being more gla- 

 brous, the leaves subentire or with very small serratures. The axils of the basal 

 leaf-nerves are often 2-glandular. Hamilton's specimens are from Goalpara ( Assam), 

 and more hairy than the others with leaves 7 by 3 in. 



10. B. polystachya, Wedd. in Ann. Sc. Nat. Ser. 4, i. 200 ; Monogr. 

 370 ; DC. Prodr. xvi. i. 215 ; glabrous, branches stout, leaves large opposite 

 or alternate coriaceous flat broadly ovate ovate-cordate or orbicular acu- 

 minate or cuspidate rather coarsely crenate or toothed from above the base, 

 spikes panicled much shorter than the leaves, fruit sessile hispid, style 

 short. Clarke in Journ. Linn. Soc. Sot. xv. 125. Urtica polystachya, Wall.

TEMPEEATE HIMALAYA ; Kumaon, alt. 7000 ft., Duthie ; Nepal, Wallich ; 

 Sikkim, alt. 4-9000 ft., J. D. H., &c. ; Bhotan and Mishmi Hills, Griffith. KHASIA 

 MTS., alt. 4-5000 ft., Griffith, &c. Ava, Wallich. 



A robust shrub. Leaves 5-12 by 2|-6 in. ; petiole stout, 2-5 in. Spikes often 

 shorter than the petioles, erect even in fruit. Weddell in DC. Prodr. says of this 

 that he formerly saw it in Herb. Wall., and then thought it a form or subvar. of 

 platyphylla. ft is, however, a much more temperate plant, and with Clarke I think 

 it must be regarded as distinct. Wallich's Ava specimen is named. B. rtigulosa by 

 Weddell, but the leaves are strictly opposite. The specimen is not in flower. 



DOUBTFUL SPECIES. 



The following Indian specie* amongst others recklessly founded by Blume (Mus. 

 Bot. ii. 216, &c.), often on very imperfect materials, are no doubt, as Weddell thought 

 they probably are, varieties of B. platyphylla. 



B. HETEBOIDEA, Bl., East Indies, Heifer, has the perianth winged and achene 

 with a thickened margin.
