 Stalks 3-4 inches high, the lower part scaly.' Leaves 4-5, about an inch 

 long and half an inch or more wide. Flowers nearly i' of an inch long-, 

 deep rose-color ; the pedicels 5-6 lines in length. Wings obovate, attenuate 

 at the base, as long as the corolla. Lateral petals obi. ng, concave, united to 

 the keel the greater part of their length : crest conspicuous, compound. An- 

 thers bilabiare, imperfectly 2-celled. Style long, a little curved, slightly en- 

 larging upward ; the orifice irregularly 4-toothed, without hairs. — In the struc- 

 ture of the flowers this species strongfy resembles P. Chamaebuxusof Europe. 



J Species of ichich the flowers and fruit are not sufficiently described. 



23. P. Nutkana (Moe. ic. ined.) : racemes loose, 4-5-flowered ; wings or- 

 bicular; capsule emarginate ; stem somewhat shrubby at the base; leaves 

 oval, petioled, acuminate at each end. DC. prodr. 1. p. 330. 



Nootka, North-west America. DC. — There is not improbably some mis- 

 take about the habitat of this plant, as no species of the genus has been 

 found by other observers on the Pacific coast of N. America. 



24. P. attenuata (Hook.): racemes loose, attenuated at the apex ; pedicels 

 as long as the flowers ; wings ovate, acute, concave, scarcely longer than 

 the bearded keel; stem slender, elongated, angular, branched ; leaves linear, 

 opposite, rarely quaternate; upper ones alternate. Jlook. in jour. bot. 1. p.

Jacksonville, Louisiana, Drvmmond. — (Tj Stems very slender, erect, about 

 a foot and a half high. Flowers greenish. — Habit of P. ambigua and P. 

 ganguinea, but very diH"erent in size, and in the flowers and racemes. Hook. 

 — We are unacquainted with this plant. The two species which it is said 

 .by Hooker to resemble are very unlike each other.

Sepals 5, or rarely 4, more or less irregular, much spreading, colored, 

 deciduous, in aestivation imbricated in a triple series; the two outer 

 ones anterior and posterior ; the two intermediate ones lateral and 

 alternate with the exterior pair ; and tiie innermost usually smaller, 

 situated either to the right or left of the posterior exterior sepal, some- 

 timcK wanting. Petals 5, or rarely 4, hypogynous, smaller than the 

 sepals ; the three superior with long and slender claws (the lamina 

 sometin>es abortive), severally alternating with the two (outer and 

 inner) posterior and the lateral sepals ; the claws sometimes united 

 into a slender column, which alternates with the two posterior sepals 

 when both are present, or is placed opposite to the exterior sepal when 

 the other is abortive ; the two lower petals (scales, abortive stamens ? 

 Kunth) opposite the lateral sepals (in K. cistoidea, ex Hook. 4' Arn. and 

 in K. lanceolata !), or alternating with these and the anterior sepal 

 (ex A. St. Hil.), sessile, fleshy, much smaller than the others and remote 

 from them. Stamens 4, hypogynous, naore or less unequal, declined ;
