No, this was part of their very small herbal garden, just about 150 sq.ft.

How is it different from Sansevieria trifasciata Prain ?

I could only find the following differences from PROSEA:

Stemless, often xerophytic, perennial herbs with leaves in a rosette borne on a subterraneous rhizome. Leaves erect, flat or concave or terete, fleshy, fibrous, often variegated. Inflorescence a terminal, erect, branched raceme, with bisexual, often fragrant flowers fascicled in the axils of scarious bracts; pedicels articulate; perianth tubular with 6 narrow, equal, spreading or recurved lobes; stamens 6, inserted in the top of the perianth-tube, equalling the perianth or often much exserted, filaments filiform, anthers versatile; pistil with superior, sessile, broad-based, 3-locular ovary, (cells 1-ovuled), style long filiform, stigma slightly thickened. Fruit a 1-3 seeded berry.

• S. roxburghiana . Leaves 6-24 over the life cycle, those of juvenile plants and the outer ones of a tuft spreading, others usually ascending; blade stiff, linear-oblong, 20-60 cm × 1-2.5 cm, deeply concave channelled down the face, rounded or slightly keeled on the back, margins entire and with age becoming narrowly whitish, apex tapering to a soft point, green, with transverse darker green rather regular bars on both sides and with 6-11 longitudinal dark green lines on the undersurface and often 1-3 on the upper. Raceme spike-like, 30-75 cm long (peduncle included), lower part with 4-5 erect acuminate sheaths 1-2 cm long; flowers 3-5 in a cluster; pedicel up to 8 mm long, jointed near the middle; tube 6-7 mm long; lobes linear, 8-9 mm long, greenish tinged with purple; stamens about 7 mm long, anthers dorsifixed; ovary obovoid, 1.5 mm long, stigma simple, obscurely lobed. Berry globose, up to 6 mm in diameter.

• S. trifasciata . Rhizome sympodial, robust, yellowish-red. Leaves in each plant 2-6, much broader than thick, fleshy to rigidly coriaceous, dark green, with numerous very conspicuous, light or greyish-green, irregularly confined transverse bonds, in the normal form with a narrow dark green margin; large leaves linear-lanceolate, 40-175 cm × 2.5-9 cm, base channelled, margins entire, apex acute. Raceme erect, 40-75 cm long (peduncle included); flower-fascicles scattered or arranged group-wise; pedicel 6-8 mm long, articulated at about the middle; perianth 2.5-3 cm long, greenish-white, scented, divided just below the middle; lobes narrowly linear, broadening towards the greenish tip; stamens 7-8 mm long; style 15-18 mm long. Berry globose, 7-9 mm in diameter, orange, 1-2-seeded. Seed globular-ellipsoid, 6-7 mm × 5 mm, cream-brown.

Thanks Garg ji for raising query for validation.

My posted plant has linear leaves (and is fitting in the range: 20-60 cm × 1-2.5 cm).

The Sansevieria trifasciata Prain page shows leaves of trifasciata clearly broader leaves.

Since I am not familiar with these ornamental, I may be ignorant of other aspects of both species.

Will wait for comments.

Regards.

Dinesh
