LEPTODACTYLON. Hook, et Am. 



Calyx tubuloso-campanulatus, subaequalis, semiquinquefidus, lobis subulatis spinescentibus, sinubus membrana- 

 ceis. Corolla infundibuliformis, limbo patente, lobis obovatis obtusis. Stamina intra partem superiorem 

 tubi inserta, sequalia. Antherce oblongae. Stylus cum stigmatibus tubo corollas duplo brevior. Capsula 

 sublignosa apice dehiscens, loculis polyspermis, columna centrali crassiuscula. — Frutices humiles, ramo$is- 

 simi. Folia alterna prqfunde palmatisecta, laciniis subulatis rigidis spinescentibus ; alia axillaria, 

 Integra, fasciculata. Flores terminales, speciosi, Phlocem simulantes. 



1. L. Californicum ; foliis patentibus, floribus subcapitatis, corollas tubo calycem sub- 

 aequante, stigmatibus stylo duplo longioribus. (Tab. LXXX1X.) 



The corolla is large. Another species of this genus is Phlox Hoolteri, Dougl. in Hook. Flor. Bor. Am. 

 2. p. 73. t. 159, which maybe distinguished as follows: foliis erectis, floribus subsolitariis, corollae tubo 

 calycem superante, stigmatibus stylum sequantibus.

1. Myosotis flaccida. Dougl. in Hook. Flor. Bor. Am. 2. p. 82. 



Our specimens are more leafy and not so much advanced as those from Columbia ; but they appear to 

 be the same species. M. versicolor, of the Flor. Bor. Am., with small flowers, seems to be M. verna of 

 Nutt., and has its calyx oblique ; the larger-flowered specimens are perhaps referrible to M. Jlaccida. 



2. M. muricata; caule erecto stricto foliisque linearibus obtusis ubique piloso-hispidis, 

 racemis densis bi-trifidis terminalibus ebracteatis, calycibus hispidis, nucibus ovatis ob- 

 tusiusculis dense muriculatis. 



From six inches to a foot high, erect, straight, rather stout, throwing out numerous lateral leafy branches, 

 which, in our specimens, are short, from not being sufficiently developed. Flowers white ; limb flat ; seg- 

 ments as long as the tube. The hairs on the calyx and raceme are yellowish-white.

The flowers are white ; the limb flat and broad ; the segments about the length of the tube. The achenia 

 are wrinkled, but not always black, and not in the slightest degree hispid or muricated.
