326 VEGETATION OF BRITISH BALUCHISTAN. 
Cynanchum pefrense, Hemsley & Lace, n. sp. 
Species humilis habitu foliis cymis pedunculisque C. Jacque- 
montit simillima sed plus minusve canescens, coronæ lobi colum- 
nam superantes, crassi, obtusissimi, lateris retroflexis, intus obtuse 
ligulati. Folliculi ignoti.—Cynanchum humile, Aztech. in Journ. 
Linn. Soc., Bot. xviii. p. 79, non Falconer. 
Baluehistan: not uncommon on rocks in Upper Baluchistan 
(Stocks, 920) ; in stony places, Shamack, Kurrum Valley (Aitchi- 
son, 44), Pil Hill (J. H. Lace, 3825). 
This and C. Jaequemontii, Decne., are so alike, except in the 
corona, that there is nothing appreciable to put in a description. 
Perhaps the follicles may afford some more tangible character. 
In the meantime we have followed Sir Joseph Hooker in 
separating them. 
Arnebia ($ Macrotomia) inconspicua, Hemsley 4 Lace, n. sp. 
-Herba perennis undique longe patenteque setoso-aculeata, 
simul strigillosa, subscaposa (depauperata ?), 4-6 poll. alta. Folia 
radicalia rigida, lineari-oblonga, 1—2 poll. longa, acuta, costa sub- 
tus elevata marginibusque precipue setosa ; caulina pauca similia, 
angustiora. Flores cerulei, dense congesti, 7-8 liueas longi; 
calycis segmenta angustissima, longissime setosa, corollam fere 
æquantia; corolla intus nuda, extus, precipue supra medium, 
dense setulosa (vel lobis hirsutis simul vere setosis), angusta, 
tubo sursum parum dilatato dein subite globoso-inflato, lobis 
parvis oblongis vix patentibus ; stamina inclusa, fauce tubi affixa ; 
ovarium glabrum, stylo brevi bifido, stigmatibus obscure bilo- 
batis. Nucul@ mature non vise sed juniores læves et glabræ. 
Zarghun at 9500 feet. Also from Zahru (Stocks, 866, in 
part), and from Cabul, collected by General Collett. 
Possibly a depauperate state of Macrotomia cyanochroa, Boiss., 
but the small, very bristly flowers, and apparently naked nutlets, 
point to specific difference. "There is also the one plant collected 
by Stocks, and confused with another species, which is exactly 
like ours, and all that could be found in the Kew Herbarium, 
except the two small pieces collected by General Collett near 
Cabul. 
Scutellaria petiolata, Hemsley & Lace, n. sp. 
Suffrutex minute puberulus vel hispidulus, caule brevi incras- 
sato lignoso ramulos floriferos multos gracillimos 6—12-pollicares
