beneath. Flowers in dense whorls or contracted cymes (fascicles) at 

 nearly every node. Ultimate cymiiles mostly of one perfect flower 

 and -i barren flowers or bi'acts enclosed between a pair of son] e what 

 unequal oblong-obovate or oblanceolate hairy and densely white- 

 •ciliate bracts •2-'3" long with sub-sqiiarrose awned tips. Calyx -15" 

 with 5 narrowly subulate acuminate segments. Corolla "25", tubular 

 part only •1--15". Capsule shortly beaked. Seeds minutely hispid 

 -or glochidiate, 06" diam.

 Fl., Fr. c.s. 



Leaves npto 3"5" in some Bombay specimens, in ours always smaller, sec. n. 4-5. 

 Sometimes several fascicles in an axillary vertical series with the inner shortly 

 peduncled and sometimes fascicles also in interrupted spikes on short axillary 

 branches. Outer lateral bracts shorter than the cymule bracts. Barren bracts or 

 flowers usually "22", oblanceolate with scarious margins, hairy, and with straisht 

 sub-aristate tips. Corolla white (always?). The proper bracts and bracteoles, 

 unless a pair of the barren bracts represent the latter, appear to be absent in this 

 species. 



31. ANDROGRAPHIS, Wall. 



Herbs or small undershrubs with entire leaves and small flowers, 

 usually erect on the branches of a spreading lax or very dense panicle 

 ■or on axillary racemes, rarely racemes subcapitate or reduced to a 

 single flower. Bracts small, and bracteoles minute or 0. Sepals 

 -equal, narrow. Corolla 2-lipped, white or pink or spotted, or lower 

 lip purple, usually pubescent ; upper lip sub-entire or deeply 2-lobed, 

 lower 3-lobed. Stamens 2 (rarely 4 in A. elongata), filaments ciliate 

 or setulose, rarely glabrous, anthers exserted with 2 oblong parallel, 

 muticous subeqxial cells bearded at the base. Ovary thinly hairy, 

 •stigma minutely 2-fld. Ovules 3-9 in each cell. Capsvile compressed 

 transversely to the septum. Seeds 6-18, bony, oblong or suljquadrate, 

 not compressed, rugose-pitted, glabrous. Retinacula sometimes 

 ■dilated at the tijDS. 



The anterior lip of the corolla is usually perfectly erect in flower, the posterior 

 spreading ! In exceptional cases 4 iDerfect stamens may be found on the same 

 plant with 2-staminate flowers. 



A. Erect symmetrical herbs. Posterior lip of corolla entire or sub- 



entire, tube half as long as flower or more, or only little 



Flowers all pedicelled. Leaves glabroiis narrow acute . . 1. panlcnlata. 

 Flowers sessile. Leaves hairy, oblong, obtuse . . . .2. echioides. 



B. Straggling, unsymmetrical. Posterior lip of corolla deeply 



2-lobed, tube one-third or less length of flower : — 

 Nearly glabrous. Flowers shortly pedicelled . . . .3. elo)igata. 



1. A. paniculata, iVees. Kalmeg, K., 8., H.; Chiretta, Beng.; Bhui- 

 nimo. Or. 

 An erect herb 1-3 ft, high with square stems glabrous below, glandular 

 hairy above, linear-lanceolate or lanceolate glabrous leaves l"o-2'5" 

 long, and distinctly pedicelled white or pale-purple flowers, spotted 

 purple, solitary and erect on the slender spreading sometimes compound 

 branches of a large pyramidal panicle, of which the lower branches 

 are from the axils of ordinary foliage leaves. Pedicles •l-'^4" slender 

 glandular-pubescent. Sepals "I-'IS", subulate-linear, glandular.
