1387. Heliotropium supinum (Lin.), stem her- 

 baceouSj decumbent: leaves oval obtuse, plicate, 

 margin obsolately crenate; incanous beneath, vil- 

 lous above: spikes sub-solitary: calyx 5-toothed, 

 closed, falling along with the enclosed fruit: fruit 

 1-3 pyrenons, 1-3-seeded. 



(?. Malaharicum^ stems ascending: leaves incano- 

 tomentose, hairy on both sides: calyx very hairy. 



A widely distributed plant, the Indian variety 

 extending from the foot of the Himalayas to Cape 

 Comorin, while the original species seems equally 

 widely distributed over the Southern States of 

 Europe and the Northern ones of Africa and Asia 

 Minor ; it is also noted as a Cape plant. 



1388. Heliotropium Coromandelianum (Retz), 

 stems herbaceous, erect or diffuse and with the 

 leaves adpressed, villous: leaves ob ovate oblong, 

 entire, mucronate: spikes ternate, conjugate, or soli- 

 tary, ebracticate: lobes of the calyx somewhat 

 unequal: corolla longer than the calyx: style 

 scarcely any: nuts sub-globose, hispid at the apex. 



A common plant, generally to be met with in 

 flower at all seasons, but in greatest perfection 

 during rainy weather. 



1389. Heliotropium scabrum (Retz), procum- 

 bent, diffuse, strigous: leaves alternate, somewhat 

 oblique, entire ; towards the ends of the branches 

 sub-opposite: flowers small, congested on the ends 

 of the branches, concealed among the leaves : 

 sepals sub-unequal, hairy: corolla scarcely exceed- 

 ing the calyx, sub-ventricose: anthers apiculate: 

 stigma dilated, shortly apiculate: nuts 4, roundish, 

 glabrous. 



Coimbatore, frequent, flowering during rainy 

 weather. 



This appears a very distinct species. The stems 

 are always spreading, hairy ; leaves small, sub-sessile, 

 ovate or sub-cordate, hairy on both sides, congest- 

 ed about the ends of the branches, where they 

 surround the small white almost sessile terminal 

 flowers: flowers small, several congested on the 

 apex of the branches, never racemose or spicate: 

 limb white, throat hairy, tube yellow, approaching 

 to orange colour. 



DeCandoUe asks whether H, hrevifoKumy Wall, is 

 H. scabrum, Retz; but gives neither the character 



Lehman seems to have taken up a form of this 

 species and described it as H. scabrum of Retz, 

 from which it is most distinct. 



1391. Heliotropium ltnifolium (LehmA suf- 

 fruticose, erect, sparingly ramous, glabrous, 4-sided 

 towards the apex: leaves linear acutish, entire, re- 

 volute on the margin, sparingly adpressed strigous 

 on both sides: racemes sub-spicate, solitary, short, 

 bractiolate: calyx very short, slightly hairy: lobes 

 of the corolla acutish, tube ventricose, pilose: nuts 

 glabrous or sometimes roughish. 



Flowers short pedicelled: corolla thrice as long 

 as the calyx, limb white, tube yellowish. The 

 difference between this and H. tenuty seems very 

 slight, I beheve, however, this is the true plant 

 from which the character of the species is taken. 



1392. Heliotropium Rottleri (Lehm.), shrub- 

 by, stems short, erect at first, afterwards dividing 

 into many divaricating somewhat horizontal branch- 

 es ; ramuli and leaves whitish strigous : leaves 

 sub-sessile, ovato-lanceolate acutish, revolute on 

 the margin: spikes lateral 1-2 inches long, cir- 

 cinate: flowers sub-sessile, secund, the under side 

 of the rachis bearing the bract : bracts ovate, 

 strigous, appressed : calyx 5-parted, lobes ovate, 

 acute a little shorter than the tube of the corolla: 

 corolla pilose externally, throat closed with hairs: 

 fruit strigous, globose: nuts 4, globose exteriorly. 



Coimbatore, frequent. In flower at all seasons. 



A very distinct but not easily described or repre- 

 sented species. The figure here given is very 

 characteristic of the more usual form, having a 

 number of branches rising direct from the root, 

 and after ascending an inch or two dividing and 

 spreading out horizontally, each, after giving off a 

 floriferous branch which becomes a raceme, length- 

 ening outwards. I have seen bushes covering sev- 

 eral square feet of surface. 



1393. Arnebia hispidissima (D. C), whole plant 

 most hispid, from rigid bristles intermixed with 

 pubescence : stem ramous from the base, erect : 

 leaves lanceolate somewhat blunt, the floral ones 

 narrower acute : spikes terminal, solitary, sub-se- 

 cund: lobes of ^the calyx sub-linear, (unequal in 

 my specimen, R. W.) about half the length of 



nor description of the latter to enable any one to ^^^^ .j^^^ ^^^^j^^ ^yj^^^ ^^^^jj^. ^^yj^ ^.^^^^ ^^^^ 



judge: thus in effect suppressing the older name 

 in favour of the newer, supposing* them to refer 

 to the sfi«ne plant, and in the event of their being 

 referable* to distinct plants suppressing this one 

 altogether because he happened not to know it! 

 I have introduced into the plate two forms, one 

 more, the other less luxuriant. 



1390. Heliotropium marifolioi (Retz), suflru- 

 ticulose, diffuse, ramuli, leaves and calyx adpressed- 

 strigous: leaves linear lanceolate acute, entire, re- 

 volute on the margin : racemes sub-spicate solitary, 

 flowers alternate, bractiate: bracts lanceolate decid- 



uous 



longer 



, -— c." than thp calyx, strigous: calyx 5- 



parted about the length of the tube of the 5-lobed 

 plaited corolla: stamens inserted on the throat: 

 anthers conate, apiculate: nuts globose, covered 



above with short rigid hairs. 



Coimbatore, not unfrequent, flowering during rainy 



weather at any season. 



rugous, somewhat 3-sided. Root slender, simple, 

 red: plant 4-6 inches high: bristles white: corolla 

 yellow: anthers inserted, either within the tube 

 or on the throat: nuts imperforate at the base. 

 D. C. prod. X. p. 94. 



Scind, common. J. E. Stocks, to whom I am 

 indebted for the specimen here represented. 



This specimen seems to agree in all essential 

 points with the character except the calyx, the 

 lobes of which are very unequal in size, occa- 

 sionally even more so than shown in the figure, 

 giving reason to suspect that this is a distinct 

 species. As however I have not a specimen nor 

 full description to which I can refer for informa- 

 tion, I do not feel justified, with my present im- 

 perfect knowledge, in giving this a new specific 

 designation, though, from the tendency said to 

 exist in this plant to variation in the position of 

 the stamens either within the tube or on the 

 throat, there is ground for suspecting that two
