This species is distinguished froiu ('ijandt vorkicca in the long flowering 

 raceme, sometimes more than twice the length of the petiole, while the racemes 

 of C. coriacca never exceed the petioles. The leaves instead of being coriaceous 

 are chartaeeous. Hillebrand misinterpreted Asa Gray's species, and unfortu- 

 nately nearly all other authors followed Hillebrand. 



Cyanea Hardyii Rock in Torrey Bot. CI. Bull. 44:236. 1917. 



(I'late 111.) 

 A small tree 5-7 m in height, with several straight ascending Iiranches bear- 

 ing large crowns of leaves at the apices; branchlets covered with leaf-scars; 

 leaves narrow, linear-oblong, chartaeeous. the margins crenulate to denticulate, 

 deiiticulations close in the upper portion, coarser and wider apart in the second 

 third, lacking at the base, midrib prominent underneath, the veins purplish, 

 closely reticulate, dark green above, light underneath, 20-30 cm long, 2.5-5 cm 

 wide, acuminate to acute at the apex gradually tapering into a margined petiole 

 '2.5-8 cm in length; racemes ver.y slender, axillary, in the axils of the leaves and 

 below the crown of leaves in the axils of the scars of fallen leaves, 20-25 cm long, 

 naked in the lower three fourths, minutely bracteate; the tiliform [ledicels bibrac- 

 teolate at the middle; flowers deep purplish black, the calyx turliinate, strongly 

 ribbed when dry, minuti ly toothed: corolla semi-curved, the dorsal slit extending 

 to the middle, glabrous, anthers and staminal column glabrous, the lower anthers

In certain respects C. TlanJi/i is intermediate between ('. Fintri( I and ('. cori- 

 acea. It differs mainly in its leaves, which are linear-oblong and acuminate, 

 tapering gradually into a margined petiole. It is further characterized by-its 

 habit and by its dark purplish black inflorescence. In C. Fauriei the leaves are 

 obovate-oblong. with longer petioles and abruptly cuneate at the base, the petioles 

 not being margined ; the inflorescence is pale lilac and more robust. 



The following species, given in their natural order, range into each other and 

 are consequently very closely related: C. coriacea, C. Faiirlfi, C. Hardi/i. C. 

 spailnilala, C. angusfifolia. C. comata and perhaps C Maiuiii and C. ohtusifoUa. 



The species was named in honor of Mr. Y. W. Hardy, Assistant Engineer in 

 the United States Hydrographic Survey. 



Ci/aiica Hnnhji has a later flowering period than C. Fauriri. The former 

 flowers in the winter months, while the latter is usually over flow-ering in 

 October. When the writer collected the last material of this species in October,
