Fiasera tubulosa sp. nov. 



Plant a biennial or short-lived perennial, in our specimens aliout 

 GO cm. high ; stem stout, terete, glabrous, glaucous, about 6 mm. 

 thick at the base ; radical leaves in a dense rosette, linear-oblan- 

 ceolate, obtuse, mucronate, reaching 1 cm. in width and 9 cm. 

 in length, usually conduplicate and the apex recurved, thick, 

 minutely scabro-puberulent, glaucou-s in appearance, its margin 

 white, cartilaginous, entire ; stem leaves similar, becoming 

 smaller above, in whorls of 5 or 6 ; inflorescence a narrow 

 spicate panicle 80 to 40 cm. long, interrupted below, its branches 

 reaching 5 cm. in length, yiostl}" shorter, erect; pedicels 2 to 20 

 mm. long, erect; sepals 4, linear-subulate, 6 to 8 mm. long, often 

 spinulose-denticulate toward the base ; petals 4, white, ol)long- 

 obovate, acuminate, 9 to 11 mm. long, slightly gibbous at the 

 l)ase; gland on the face of the petal none, but represented by 

 a tube of the same texture, and half as long, as the corolla, in- 

 serted over the gibbosity at the base of the i^etal, S})lit about 

 half way to the base in a direction tangential to the axis of the 

 flower, the posterior lobe slightly larger and both lacerate-fim- 

 briate ; stamens 4, filaments about as long as the sejjals, anthers 

 oval, 2 mm. long ; ovary compressed, oblong-lanceolate, taper- 

 ing into 2 subulate appressed styles, the whole equalling the 

 stamens ; placenta at the edges of the ovary, not intruded ; 

 ovules 6 to 10, ol:)long, very thin and flat ; stigmas recurved- 

 spreading, flat, hardly broader than the style ; capsule very 

 flat; valves obovate-oblong, with callous thickened margins and 

 1 median nerve continued into the stiff subulate persistent style, 

 the whole 12 to 14 nnn. long; seed single, lamelliform, oblong, 

 minutely cellular-muriculate, about 5 to 7 mm. long. 



This plant differs from all other species of the genus in the 

 api)arent al)sence of the petaline gland and in the presence of the 

 tuljular nectary described above. The leaves are very similar to 

 those of F. albomarginata, while the form of the inflorescence re- 

 seml)les that of F. nitida and F. albicaulis.
