 " a species of ^f^sculus, i,TO\ving near Cincinnati, Ohio, which resembles 

 JE. flava, but differs in the deep orange and yellow hue of its flowers, in its 

 glabrous irregularly serrate leaves, and more acute divisions of the calyx." 



X Uncertain species, probably forms icJiich have originated in gardens. 



G. ^-K. carnra (Willd.) : capsules ccliinatc ; stamens 7, longer than the 4-petalo(is

7. .K. (suh Pavia) Watsoniana (Sp-dch) : capsules echinate ; flowers octandrous 

 (dark red) ; claws of the lateral petals a little shorter liian the calyx ; stamens some- 

 what shorter than the lateral petals ; the anthers pubescent along the margin ; leaf- 

 lets 5-8, sessile, lanceolate, acuminate, glabrovis. Spach, I. c. p. 53. 



This species, according to Spach, is the JE. carnea, Watson, dendr. Brit. i. 121. 

 {JE. rubicunda, Lodd. bat. cab. t. r2-12.): the description seems to have been drawn 

 merely from Watson's figure. 



8. ^'E. hu7niJ-is (Lodd.) : capsules unarmed ; stem decumbent; leaflets 5, lanceolate, 

 petiolulate, unequally serrate, jiubescent bencatli ; calyx cylindrical-fiinncl-shaped 

 and pubescent, as well as the corolla; stamens included, a little longer than the ca- 

 lyx ; flowers blood-colored, in loose racemes. G. Don, sub Pavia. — " Lodd. ; Lindl.

2. UNGNODIA. Endl. atakta botanica, p. .. t. . 



We have not yet received the above-cited work of Endlicher, in the fifth fiisciculus 

 of which (according to Sir Wm. Hooker) this very remarkable genus is figured 

 and described. The plant was collected by the late Mr. Drummond in Texas, and 

 specimens were distributed witii his first Texan collection. It forms a large tree; 

 the leaves are alternate, and pinnately 5-foliolate : the flowers are small, in few-flow- 

 ered racemes, which appear to be axillary or clustered along the branches : the se- 

 pals are nearly distinct : petals 5 (rarely 6), similar, spreading, witli an obovate 

 slightly crenulate lamina, raised on a short and very thick woolly claw, which bears 

 at its summit a curious fimbriate crest: stamens 8-10, declined and much exserted, 

 a portion of them apparently somewliat coherent with a small unilateral appendage 

 orprojectiou of the torus, or with the base of the (effete 1) ovary. Fruit not seen. 



Order XLV. SAPINDACEiE. Jiiss. 



Flowers usually polygamous. Sepals 4-5, distinct or nearly so, im- 

 bricated in aestivation. Petals as many as the sepals and alternate 

 with them, or fewer by the abortion of one (sometimes entirely wanting), 

 inserted outside the hypogynous disk (or row of glands) which occupies 

 the bottom of the calyx ; the inside either naked or hairy, glandular 

 or furnished with a petaloid scale. Stamens 8 or 10, rarely fewer or 

 more numerous, inserted either on the disk, or between the glands and
