ON THE PLANTS COLLECTED BY DR. WALKER IN GREENLAND. 79 



have since then received Mr. Fendler's own specimen of the plant 

 with fully expanded flowers, and, although the fruit is as yet un- 

 known, the calyx and anthers are so different from those of any 

 others of the tribe, that I have no longer any hesitation in charac- 

 terizing it as a new genus, as follows : — 



Fissicalyx, gen. nov. Dalbergiearum. 



Calycis tubus turbinatus, limbus acuminatus integer v. apice minute 

 denticulatus per anthesin hinc fissus, spathaceus. Petala ad apicem 

 tubi cum slaminibus inserta. Vexillum angustum. Al;c eo vix breviores, 

 oblique oblongse. Carinas petala subsimilia, paullo minora, libera. 

 Stamina 10, monadelpha, vagina supra fissa. Antherae versatiles, apice 

 biporosoe. Ovarium breviter stipitatum, biovulatum. Stylus filifor- 

 mis apice minute stigmatoso. 



Species unica, F. Fendleri. Arbor. Folia impari-pinnata. Foliola(ll) 

 opposita, exstipellata, petiolulata, inferiora ovata, superiora oblonga 

 acuminata, 3-4-pollicaria, basi rotundata v. subcordata, glabra, mem 

 branacea. Panicula terminalis, molliter pubescens. Bractea: stipula 

 res ad basin ramorum parvae, sub floribus minuta;. Flores conferti 

 Pedicelli ad singulas bracteas solitarii v. gemini, vix lineam longi 

 Bvacteolse parvae, acuta;, persistentes. Calyx semipollicaris, pubescens 

 subfoliaceus, apice longe basi brevius attenuatus, summo apice mi 

 nute penicillatus. Petala aurantiaca, calycem paullo superantia 

 breviter uuguiculata. Vexillum basi complicatum, nee auriculatum 

 nee appendiculatum, erectum, lateribus reflexibus. Alae et petala 

 carinalia basi hinc rotundato-auriculata. 



Hab. In Venezuela, between Turmero and Maracai, at an elevation of 

 1 700 feet.— Fendler, no. 2223. The loose fruits distributed with the 

 specimens are evidently mismatched. They are those of a Guai- 

 acum. 



An Account of the Plants collected by Dr. Walker in Greenland 

 and Arctic America during the Expedition of Sir Francis 

 M'Clentock, E.N., in the Yacht 'Fox.' By J. D. Hooker, 

 Esq., M.D., F.R.S., F.L.S., &c. 



[Read June 21, I860.] 

 On the termination of Capt. M'Clintock's memorable voyage, 

 the plants collected by Dr. Walker, Surgeon and Naturalist to 

 the Expedition, were placed in my hands by that officer for deter- 

 mination, together with some accurate notes of the localities, 

 and of the temperature of the soil and air to which they are ex- 

 posed in their native habitats. Though containing no absolute
