* Perennial. 



1. Ziziphora CLINOPODIOIDES M. Bieb. ; shrubby, branching from 

 the base, leaves glabrous or pubescent, ovate oblong or lanceolate, floral 

 similar smaller shorter than the flowers, whorls capitulate, calyx nar- 

 rowly cylindric, teeth very short linear lanceolate blunt upper rather 

 longer, corolla tube shortly exserted, anthers-cells equal. — Ziziphora 

 clinopodioides M. Bieb., Flor. Taur.-Oauc, i, 17 ; Benth., DG. -Prodr. 

 xii, 364 ; Boiss., Flor. Orient., iv, 585. 



Rootstock stout woody, stems or branches usually numerous 6 — 15 

 cm. high, often fastigiafce, leaves 0'5 — 0'75cm. long - 25 — 0"35 cm, wide, 

 capitula 15 cm. long 2 cm. across, calyx 8 mm. long 2 mm. wide, corolla 

 11 mm. long. 



The typical form of this variable plant does not occur within Indian 

 limits, the following varieties are reported : — 



a. Var. Benthami ; calyx pilose with white spreading hairs. — ■ 

 Ziziphora clinopodioides var. canescens Boiss., Flor. Orient., iv, 585 

 (1879) [not Z. clinopodioides var. canescens Benth., Lab. Qen. et Sp. 321 

 (1833) and DO. Prodr. xii, 3fa5 (1848)]. — Z. canescens Benth., Lab. Gen. 

 et Sp. 621 (1833) and DG. Prodr. xii, 365 (1848) ; Aitch. Sp Hemsl., 

 Trans. Linn. Soc, n. s. iii, 96 (1888). 



N. W. Himalaya ; Gilgit, Giles. Distrib. Soongaria, North Per- 

 sia, Kurdistan, Armenia. 



After close examination it seems impossible to deal with this plant 

 otherwise than as M. Boissier has dealt with it. As regards floral struc- 

 ture it in no way differs from typical Z. clinopodioides. M. Boissier's 

 varietal name is, however, preoccupied ; it was employed by Mr. 

 Bentham 46 years previously to designate precisely the plant termed by 

 M. Boissier, loc. cit., Z. clinopodioides var. serpyllacea. 



/?. Var. rigida; calyx hirsute with adpressed hairs or almost 

 glabrous. — Ziziphora clinopodioides VAR. rigida Boiss., Flor. Orient., iv, 

 586 (1879). 



Panjab frontier ; Beluchistan, assigned districts, Lace. Distrib. 

 Beluchistan, Afghanistan, Persia, Armenia. Leaves usually much 

 smaller and stems more rigid than in the other varieties. 



* * Annual. 



2. Ziziphora tenuior Linn. ; hei'baceous, simple or branching 

 from the base, leaves distinctly nerved scabrid ciliate narrowly lanceo- 

 late acute, floral similar longer than the flowers, whorls axillary along 

 the stem in lax or dense oblong spikes, calyx narrowly cylindric, teeth 

 very short triangular-ovate blunt, corolla tube shortly exserted, lower 

 anther-cell small empty. — Ziziphora temiior Linn., Sp. PI. 21; Benth., 

 Lab. Gen. et Sp. 322 and DG. Prodr. xii, 366 ; Boiss , Flor. Orient, iv,
