more or less fascicled in the axils; stipules short, glandular-setiferous : 
inflorescence in terminal rather few-flowered dichotomous cymes; flowers 
subsessile or short pedicellate: calyx deeply 5-lobed with a single stipi- 
tate gland in each sinus; lobes linear-lanceolate, about 3 mm. long, folia- 
ceous: corolla about 3 times longer than the calyx; tube narrowly

§ 38. Macronovstonia. Erect shrubby pot with ovate leaves and 
rather large flowers. — Gray, Proc. Am. Acad. iv. 314. A section 
scarcely to be retained. 
Sig > & ouvardioides, Benth. & Hook. f. Shrub 8 to 4 feet high: 
- stems terete, granular-puberulent: leaves opposite or ternate, short-petio- 
o 
late, ovate or elliptic-lanceolate, acute or short-acuminate, entire, finely 
puberulent upon either surface, especially upon the midrib and veins : 
inflorescence in terminal compound minutely pubescent cymes: calyx 
deeply 4-parted ; divisions linear, 3 mm. long: corolla funnelform, about 
12 mm. long, glabrous, rather deeply 4-lobed ; tube with a few scattered 
hairs on the inside toward the base; lobes oblong, obtuse: anthers long- 
exserted: style included (probably dimorphous) ; ovules rather numer-. 
ous: seeds not seen. — Gen. ii. 60; Hemsl. Biol. Centr.-Am. Bot. ii. 30. 
Hedyotis (§ Anotis) bouvardioides, Seem. Bot. Herald, 296, t. 64. — N. W. 
Mexico,Seemann. A plant having much more in common with Bouvardia 
than with Houstonia, but without fruit or mature seeds it seems unwise to 
make the transfer. More complete . Seegeate however, may justify its 
_ removal to the former genus.
