rosacea. 499 



A diminutive species, with short branching caudexes, crowned with 

 a very dense rosulate cluster of leaves, each half an inch or an inch long, 

 including the petiole, which is winged for nearly its whole length by 

 the adnate and scarious, brownish, glabrous stipules. Leaflets 7 or 8 

 pairs, crowded, very small, about a line in length, ovate or oblong, com- 

 monly two-lobed or two-toothed, sometimes three-toothed, otherwise entire, 

 rather coriaceous in texture, the convex upper surface bullate, reticu- 

 lately veiny under a lens, glabrous and somewhat shining ; the lower 

 surface concave, whitened with a very minute close-pressed pubescence, 

 and with stouter hairs on the veins and midrib ; the latter somewhat 

 projecting into a bearded point. Scape slender, 4 to 6 inches high, 

 minutely pubescent, leafless, beset with a few subulate bracts, which 

 are chiefly opposite : from most of them in the collection the flowers 

 and fruit have wholly fallen ; but one or two, in an effete state, show 

 the inflorescence to be a small, cylindncal spike, not more than half 

 an inch in length. Flowers minute, crowded, subtended by subulate 

 or linear bracts. Calyx-lobes 4 or 5, oblong, glabrous ; the ovoid tube 

 covered with slender bristles (as in Eaacodna), which are minutely 

 relrorsely barbed at the apex, otherwise smooth. The flowers are pro- 

 bably hermaphrodite : at least, in a spent flower, the remains of two 

 filaments were detected, and also a sessile, dilated and depressed, fim- 

 briate stigma. Anthers not seen. Mature fruit unknown. 



Incomplete as the specimens are, they suffice to show that this is a 

 new and. peculiar species of Accena. The leaflets are not larger than 

 the leaves of many a Jungermannia, which, indeed, they considerably 

 resemble, except in their rigidity.
