TuELYPODiUM SAGITTATUM, Endl. {Pochypodium, Nutt.) Leaves 



' THELYPODIUM, Endl. (See note to Streptanfhua, on page 19.) Sepals elongated, equal at base, 

 often colored. Petals long, liueai, or with a plane lamina, unguioulate. Anthers linear. Siliqne sessile or 

 with a very short thick stipe, linear, suhterete or somewhat compressed, torulose, not greatly elongated ; 

 valves convex, subcarinately 1-nerved ; style rather short ; stigma nearly entire. Seeds in one row, 

 oblong, somewhat compressed, immarginate or scarcely margined ; cotyledons more or less incumbent. — 

 Annual or perennial, With spioately facemed bractless white or rose-colored flowers ; silique 1-2^' long. 

 The genus includes the following species : 



* Leaves entire. 



T. INTEGRIFOLIUM, Endl. (See above.) 



T. LiNEAEn'OLiUM, Gray. {Streptantlins, Gray. Plant. Fendl, p. 7.) Leaves linear, the lowermost 

 lanceolate, narrowed at base ; flower showy. New Mexico. 



T. SAGITTATUM, Eudl. See above. 



T. NuTTALLn. See p. 26. 



** Radical leaves, at least, toothed or pinnatifid. 



T. BRACHYCAKPUM, Torr. See p. 26. 



T. LACINIATUM, Endl. See p. 26. 



T. LONGIFOLIUM. (Streptantlius, Benth., Plant. Sartw., p. 10, and probably S. mlcranthus, Gray, 

 Plant'. Fendl. p. 7.) Lower leaves rough-hirsute ; pod sub-pendulous. New Mexico. 



T. PINNATIFIDUM. (lodanthus Twsperidoides, Torr. & Gr.) Glabrous, leaves all toothed, lowermost 

 lyrate-pinnatifid ; racemes loose, panicled. From the Alleghanies to Illinois and Arkansas. 



T. FJCAVESCENS. (Streptantlius, Torr., Pao. B. U. Surv. 4. 65; not of Hooker.) Pilose; upper 

 leaves sessile and entire ; pods hirsute, erect.— Whipple's plant in Herb. Torr. has a nearly terete pod, 

 witli oblong flattened seeds, the radicle oblique at base. Dr. Gray, in his MSS. notes upon Douglas's 

 plant in Herb. Kew., but for its leaves not auricnlate at base, would consider it a depauperate, small- 

 flowered form of S. heteropnyllus, Nutt., which, however, has flattened pods and small flat orbicular 

 slightly margined seeds and is a true Streptanthvs. California.
